Figure 3-1 - Connecting to a USB Host or USB Charger. Left: Countertop Models. Right: Kiosk Models

To connect DynaFlex II products to a USB host or charger using the USB-C port, follow these steps (for reference see Figure 3-1 and About DynaFlex II Components):

1. For best results, use the cable that is included with the device or another cable from Table 1-2 – DynaFlex II Accessories on page 7. These cables are designed specifically for DynaFlex II products and include ferrite shielding at both ends of the cable to reduce emissions and interference. If the solution design requires an alternate cable, contact MagTek for assistance with ferrite selection and placement, and with connector overmold design.

2. Connect the USB-C end of the cable to DynaFlex II or DynaFlex II PED.

3. If you plan to route the cable out the back of the device, route the cable through the cable management clip to change its direction. Even if you are not routing out the back, you may use the cable clip for strain relief, to help stabilize the mechanical connection when cardholders or operators move the device or the cable.

4. Route the cable in the desired direction (e.g., out the back, left, right, down into the countertop, or into the mounting compartment of a kiosk).

5. Connect the other end of the USB cable to the charger or to the host’s USB port.

6. As soon as the device starts receiving power through USB, it automatically powers on.

7. If the specific device serial number you are connecting has not been connected to the host before, the device shows Welcome on the display, and the Windows system tray on the host reports it is Setting up a device (see Figure 3-2 - Setting Up a Device), When installation is complete (approximately 30 seconds later depending on the host), Windows reports Device is ready,(see Figure 3-3 - Device is Ready) and the device shows in Windows Device Manager under Human Interface Devices as two devices HID-compliant vendor-defined device with VID 0801 and PID 2020 and USB Input Device.

Figure 3-2 - Setting Up a Device

Figure 3-3 - Device is Ready

1. After successfully connecting to the host operating system via USB, devices with a touchscreen display a Welcome screen or a customizable graphic.

2. The operating system may put the device into USB Suspend mode. See section 4.6.6 About USB Suspend.

The DynaFlex II product line offers versatile mounting solutions, including:

• Integrated Slip-Resistant Adhesive Strips: The underside of the device features three adhesive mounting strips (see Figure 3-4) that provide secure attachment to any clean, non-porous surface. These strips come with a protective film that must be removed before installing onto a surface.

Figure 3-4 - Adhesive Mounting Strip and Protective Film

• Lanyard Mount Point: The integrated mount point allows the device to be hung or carried, making it easy to store and handle, particularly in grab-and-go payment environments (see Figure 3-5).

Figure 3-5 - Lanyard Mount Point

• Charging Station Compatibility (Non-Kiosk Models): Non-kiosk versions of the device can be placed in an optional charging station. This station can be used in conjunction with the lanyard mount point for quick access and easy drop-in charging between handheld uses.

Figure 3-6 - Charging Station Compatibility

• Custom Mounting Options: DynaFlex II devices can be attached to custom mounting brackets or housed within an enclosure, enabling integration into larger system designs.

1. Verify that the protective film has been removed from the adhesive mounting strips located on the underside of the device (see Figure 3-4).

2. Mount DynaFlex II devices onto a smooth, flat, and non-porous surface by pressing the device firmly using the adhesive mounting strips (see Figure 3-7).

Figure 3-7 - Mounting DynaFlex onto a Nonporous Surface

1. Do not mount the device on rough, dirty, or uneven surfaces.

2. To uninstall the device, twist it to disengage the mounting feet from the mounting surface.

For instructions on using the optional charging station, refer to How to Mount the Charging Station.

If your installation requires custom mounting brackets, contact your MagTek representative for design advice and assistance from MagTek’s Engineering team.

This section provides information and guidelines for designing the mechanical aspects of a solution that incorporates DynaFlex II Kiosk models. MagTek strongly recommends vetting and testing solution designs before finalizing and deploying them to make sure the design meets all requirements (e.g., functional, legal, security, certification, safety, and so on).

When designing the mechanical portions of a solution that incorporates DynaFlex II Kiosk models, consider the following:

• Review About DynaFlex II Components for an overall introduction to the device’s physical features and what they are called.

• Review Appendix A Technical Specifications.

• Review the information below about overall device dimensions and mounting hole locations and use.

• Determine device orientation. The device supports all four orientations.

Overall dimensions of the device are shown in Figure 3-8 and Figure 3-9. On request, MagTek can provide a 3D model of the device’s envelope to assist with the mechanical portion of solution design. MagTek strongly recommends building and testing prototypes with actual devices before finalizing the solution design.

Figure 3-8 – DynaFlex II Kiosk Models Overall Dimensions

The screw hole placement on the bottom of DynaFlex II Kiosk models is detailed in Figure 3-9. The holes are designed to accommodate screw size M4 x 0.7mm and a maximum screw depth of 0.315 inches (8mm). The recommended torque range for installing the screws is 20 to 22 in-lbs. (2.3 to 2.5 N-m).

Figure 3-9 – DynaFlex II Kiosk Models Mounting Hole Locations

When designing an enclosure or mounting bracket, make sure there is adequate clearance for cardholders to swipe, insert, and tap. If the solution design includes metal objects anywhere near the device, including metal enclosures, ensure that at all points the metal is no further forward than 15mm below the top face of the device. Proximity to metal can adversely affect the device’s performance.

Figure 3-10 - Unobstructed View of Card Insertion Slot, Swipe Path and Contactless Landing Zone

As a security measure, the device must be installed such that cardholders have a full, unobstructed view of the housing around the card insertion slot opening (“entry zone”) and MSR swipe path prior to insertion or swipe (see Figure 3-10). This is to allow cardholders to easily detect suspicious objects in or around the swipe path and card slot entry, such as bugs / skimmers / tapping mechanisms, and their wires or antennas. Be sure to select an installation height and mounting angle that meet this requirement.

To mount the optional charging station to a countertop using the four adhesive mounting strips on the underside of the charging station (see Figure 3-12), follow these steps:

1. Determine where the charging station will be placed.

2. Remove the adhesive strip protective film, ensure the mounting surface is a clean, smooth, and flat surface. It is important to avoid rough, dirty, or uneven surfaces.

3. Consider the cable length, cardholder and operator ergonomics, and access for cleaning, maintenance, and repair.

4. If the charging station will be used for charging in handheld operations, unobstructed connection and disconnection of the device from the charging station is also a consideration.

Figure 3-11 - Charging Station Dimensions

Figure 3-12 - Charging Station Mounting Surfaces and Screw Holes

To mount the charging station to a countertop, table, or flat surface using the screw holes on the underside of the charging station (see Figure 3-12), follow these steps:

1. Determine where the charging station will be installed.

   1. Mark the location of the screw holes by placing the device over the area where it is to be installed (see Figure 3-13).

   2. Once the appropriate measurements have been taken and marked, drill the screw holes into the installation surface. Using (2) M4 x 0.7mm thread pitch (not included) screws, screw up through the drilled holes in the mounting surface, see Figure 3-14.

2. Connect the charging station to a USB port or to a USB charger with a minimum of 1A current capability. For the best results, use the cable that is included with the device. It includes shielding at both ends of the cable to reduce interference.

(2.3 to 2.5 N-m).

When mounting DynaProx, make sure gasket is seated properly to ensure IP65 rating, see Figure 4-9.

The suggested panel cutouts for the USB and RS-232 connectors are shown in Figure 4-10 with a DynaProx shown for reference. The dimensions for the suggested panel cutouts are shown in Figure 4-11.

When designing the enclosure or mounting bracket, make sure there is adequate clearance for cardholders to tap or users to present a bar code. If the solution design includes mounting to metal surfaces, there will typically not be any impact to performance or card reading range. If the design of the enclosure includes mounting the DynaProx such that the top surface is flush with adjacent metal on the same plane, the range of the contactless reader may be reduced. By keeping the card reading plane a few millimeters above any adjacent metal surfaces or providing a few millimeters of gap between the reader and adjacent metal will assure acceptable card reading performance. Proximity to metal can reduce the device’s reading range.

DynaFlex II is a secure card reader authenticator engineered for attended, unattended, and mobile payment environments. The reader features a magnetic stripe reader, EMV chip reader for both contact and contactless cards, an optional barcode reader, and support for NFC-enabled mobile wallets such as Samsung Pay®, Google Pay®, Apple Pay®, and Apple VAS. DynaFlex II communicates with host devices via USB or wireless local area network (WLAN) on pin entry devices (PED). DynaFlex II products are compatible with iOS, Android, and Windows operating systems.

In this document, DynaFlex II products are referred to as the device or inclusively as DynaFlex II products. They are designed to be connected to a host, which is a piece of general-purpose electronic equipment which sends commands and data to, and receives data from, the device. Host types include PC and Mac computers/laptops, tablets, and smartphones. The host must have software installed that communicates with the device and is capable of processing transactions. During a transaction, the host and its software interact with the operator, such as a customer service representative, while the device interacts with the cardholder (even if the cardholder is using a virtual representation of the card account, such as a smartphone).

Throughout this document:

• DynaFlex II Product Family refers to all devices in the DynaFlex II family, including all DynaFlex II models and DynaFlex II PED models.

The operator initiates a transaction from the host, and the cardholder interacts with the device. Transaction types may include retail transactions, new accounts, teller window applications, checking, savings, mortgages, and any other type of transaction where there is interaction between the cardholder and the operator.

For each transaction type, the host software directs the cardholder. The transaction flow on the device may differ depending on what the host software specifies and what the cardholder does. Section 7.9 Card Reading provides examples of the cardholder experience for each type of payment. If the device cannot read payment data, the host software may require the cardholder to repeat the action or require the host to reject the transaction.

All DynaFlex II Go devices have a single physical button, see Figure 6-1 - Power Button. Pressing and holding this button can activate extra functions. To active a specific function, press and hold the button until a specific number of beeps are heard. Table 6-1 - Button Functions contains functions that can be activated. Beep counts that are not listed are not supported.

Barcode symbology refers to the way in which data is encoded in a barcode. It uses either spaced lines, dots, or squares. When read, these symbols are decoded and converted to data. The table below lists all of the supported symbologies and which are enabled by default.

Custom host software uses the same underlying device command set for all DynaFlex II Go product connection types. This section provides high-level information about communicating with the device via the various physical connection types in various software development frameworks, and provides pointers to available SDKs, which include sample code. Product documentation and SDKs are available for download by searching for the product name on and navigating to the tab.

MagTek provides convenient SDKs and corresponding documentation for many programming languages and operating systems. The API libraries included in the SDKs wrap the details of the connection in an interface that conceptually parallels the device’s internal operation, freeing software developers to focus on the business logic, without having to deal with the complexities of platform APIs for connecting to the various available connection types, communicating using the various available protocols, and parsing the various available data formats. Information about using MagTek wrapper APIs is available in separate documentation, including:

• D998200380 MagTek Universal SDK Programmer’s Manual (Microsoft .NET)

The device always encrypts account data from the MSR using 112-bit TDEA, 128-bit AES, or 256-bit AES algorithms with X9.24 DUKPT key management. This device does not support any mechanisms such as whitelists or SRED disable that would allow the data to be sent out unencrypted. The programmers need to follow the guidance provided in [3]. Use of the device with key-management systems not described in this policy will invalidate the PCI PTS POI v6.2 approval of the device.

The device includes the following cryptographic algorithms:

• AES-128/256

• TDEA-128

The device does not have an on-screen configuration interface. However, it does have settings the host can change using commands. These settings are documented as Properties in D998200597 DynaFlex II Go Programmer’s Manual (COMMANDS).

Initial Inspection

After receiving the device, the customer should visually inspect the product as follows:

About Reading Cards

The steps for starting a transaction and reading a contactless payment device are different depending on the device’s configuration and on the design of the host software. Host software developers should see section 9 Developing Custom Software for implementation references. The solution developer should provide solution-specific instructions for operators to follow. A transaction generally follows this essential flow:

• An advanced operator has already made sure DynaFlex II Go is configured properly and is connected to the host (see section 4.3 Connecting DynaFlex II Go to a Host). When the device is connected to the host and powered via the USB-C connector or internal rechargeable battery, the host software may keep a connection open to the device.

• The operator makes sure DynaFlex II Go is receiving power either from the USB connection, or from the internal rechargeable battery, and is awake and powered on (see section 7.8.3)

• The operator uses the host software’s user interface (for example, a point of sale) to finalize a transaction amount, then initiates a transaction. In solutions that are designed to respond to cardholder input events that occur when the device is idle, such as unprompted tapping of a card or electronic payment device, the host software may respond to those inputs by notifying the host. The host software may trigger other operations without being initiated by an operator (for example, the host software may immediately start a transaction, or alert the cardholder or operator to take action).

• The host communicates with the device, and reports to the operator when the device is ready.

• The operator guides and assists the cardholder in presenting payment.

• The cardholder interacts with the device to present payment. The following sections provide additional details about presenting each of the available payment methods.

• The host monitors the progress of the transaction, and when necessary, and should report issues to the operator, who may need to relay the messages to the cardholder.

• The device reports the success or failure of the transaction to the cardholder and to the host.

To tap a contactless card or smartphone, follow these steps:

• Check LED status:

  • The device shows the transaction status using the LEDs. LED1 lights solid and all other LEDs are off, per EMV standards, to indicate it is ready for a tap.

  • All devices report detailed transaction status to the host, and host software may report that information to operators so they can guide cardholders through the transaction (for example, “please tap your card now”).

• If the cardholder is using an electronic payment device, such as a smartphone, make sure the payment device has NFC turned On and has a payment app configured to process transactions. For details, see the documentation provided by the smartphone manufacturer and payment app publisher.

Figure - Tapping a Contactless Card / Smartphone

Figure – Contactless Read LED Sequence – Read Complete (Connected via Bluetooth® LE)

To scan a barcode, follow these steps:

• Make sure you are using a DynaFlex II Go model that includes a barcode reader, indicated by QR Code markings on the face of the device surrounding the barcode reader lens (see section 1.1 Key Features and Components).

• If the barcode being scanned is not on a self-illuminated source such as a smartphone, make sure there is enough ambient light for the camera to read the barcode. In low light conditions, the barcode reader will only be able to read self-illuminated sources.

• In some solutions, the operator may have to perform an operation in the host software to enable the barcode reader, or to start a transaction with the barcode reader enabled.

DynaFlex II Go products support Apple Value Added Services (Apple VAS) protocol.

Contactless transactions using the Apple VAS protocol permits the device reader to perform the following supported operations:

The device reads both Apple VAS data and EMV payment data from a tapped smartphone or reads EMV payment data from a tapped card. When device sends ARQC to the host to conclude the transaction, it includes EMV payment data in container FC and includes VAS data, if available, in container FE

The device reads only Apple VAS data from a tapped smartphone and does not read data from a tapped card. If the tapped smartphone does not support VAS, the device does not detect or read from the smartphone. When the device sends ARQC to conclude the transaction, it includes VAS data in container FE and does not include EMV payment data in container FC.

The device reads only Apple VAS data from a tapped smartphone or reads EMV payment data from a tapped card. When the device sends ARQC to conclude the transaction, it only includes either EMV payment data in container FC for cards, or includes VAS data in container for smartphones.

The device operates the same as EMV mode (01). It reads only EMV payment data from a tapped smartphone or a tapped card. When the device sends ARQC to conclude the transaction, it includes EMV payment data in container FC and does not include VAS data in container FE. Note: THIS MODE MAY NOT BE NEEDED.

For details, see D998200597 DynaFlex II Go Programmer’s Manual (COMMANDS).

1.1.1 How to Tap Contactless NFC Tags / MIFARE Classic / MIFARE DESFire /MIFARE Plus Cards and Send Pass-through Commands

DynaFlex II Go is compatible with near field communication (NFC) technology such as MIFARE Classic/MIFARE DESFire /MIFARE Plus contactless IC products (smart cards).

To tap an NFC Contactless IC product and send pass-through commands, follow these steps:

• Check LED status:

  • Per EMV standards, the device indicates transaction status through its LED indicators, located on the front face of the device. When ready for a tap, LED 1 is steadily illuminated while all other LEDs remain unlit.

  • All devices communicate transaction details to the host. The host software will relay this information to operators, allowing them to direct cardholders during the transaction, such as prompting "please tap your card now".

A Barcode symbology refers to the way in which data is encoded in a barcode. It uses either spaced lines, dots or squares. When read, these symbols are decoded and converted to data. The table below lists all of the supported symbologies and which are enabled by default.

Barcode Reader Supported Symbologies

The guidelines in the following sections are intended to help project planners and system administrators plan for the physical and logical requirements of deploying and using DynaFlex II Go products. The most effective way to ensure smooth deployment of a solution is to consider these factors before receiving the device.

Logistical Planning

• Determine what type of host DynaFlex II Go will connect to. For a list of supported device types and operating systems, see Table - Available Models and Options. When planning, be sure to include any additional support or devices required by the host and DynaFlex II Go, such as physical locations, mounting, power connections, and charging cradles.

• Determine what connection the host will use to communicate with the device. The available connections are USB-C for power and control and Bluetooth® Low Energy (LE) for wireless connectivity (see Table - Available Models and Options).

• Determine what software will be installed on the host and how it will be configured. Software can include the operating system, transaction processing software, security software, and so on. If teams other than the software development team will be involved in preliminary device testing, MagTek recommends the solution development team provide a smoke test harness early in the development process to allow basic testing (for example, communication adapter testing). In addition, be sure to plan for any additional support required by the software, such as software licenses and network connections. Information about software is provided in section 4.2 About Host Software.

• Determine how the device will be physically presented to the cardholder. If the device is mounted, make sure there is adequate clearance for cardholders to swipe, insert, and tap. If the solution design includes metal objects anywhere near the device, including metal enclosures, make sure that at all points the metal is no closer than 15mm from the MSR swipe path or card insertion slot. Proximity to metal can adversely affect the device’s performance.

• Determine how the device should be configured and specify that configuration when ordering the device. A full list of configurable options is documented in D998200597 DynaFlex II Go Programmer’s Manual (COMMANDS).

• Select and configure a secure workstation that advanced operators will use to configure and/or update the device. The workstation must be configured as follows:

  • Available USB port.

  • A secure means of obtaining files, either via the network (such as SFTP) or via removable media, such as USB flash drives. This is required for installing software tools, copying firmware files, etc. If you are using Magensa Services, make sure the secure workstation has an internet connection and has all the required Magensa Remote Services software components installed.

• Determine the final set of tools advanced operators will use to configure, test, and update the device. This documentation uses the 1000007406 DynaFlex, DynaProx Test Utility as an example for configuring the device; it can be used for initial pre-deployment testing and development, and as sample code showing how to communicate with the device, but the full solution may call for customized, solution-specific software for configuring the device and updating firmware.

• Determine how to inspect devices upon arrival, upon installation, and periodically during live usage, to ensure malicious individuals have not tampered with them. Details about inspection are provided in section 4.1 About Inspection.

• Develop procedures for maintaining the device(s). Detailed guidance is provided in section 8 Maintenance.

• Determine how to train operators. For example, training may include information extracted from section 5 Configuration, section 6 Operation, and section 8 Maintenance.

• Review the device’s PCI Security Policy, posted to the PCI web site under Approved PIN Transaction Security (PTS) Devices, for additional information about using the device securely.
