The following documents may be used to provide additional details about the device and this security policy:

• MagTek iDynamo 5 Gen III Installation and Operation Manual PN: D998200614

• MagTek iDynamo 5 Gen III SRED, Device Inspection Manual PN: D998200620

Initial Inspection

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

• Inspect the label found on the back of the device (see section 2.3.1 Hardware Identification) and make sure the label is not missing, obscured, or modified.

• Check the PCI Hardware Identifier on the device label and make sure it matches the Hardware # listed for the device on the PCI website for Approved Devices. Go to the PCI compliance web page and search for MagTek, and find the product name, iDynamo 5 Gen III. Compare the Hardware ID and Firmware ID: https://www.pcisecuritystandards.org/assessors_and_solutions/pin_transaction_devices

• Check the Device serial number (SN) and make sure it matches with labels on shipping materials and documentation.

• Visually inspect the device, per [2], which is included in the package with each device. See section 4.1 Periodic Inspection for more information regarding visual inspection of the device.

• Follow the steps in Firmware Identification to view the PCI firmware versions installed on the device. Make sure this matches one of the Firmware # values listed on the PCI web site for iDynamo 5 Gen III.

Connect the device to a host via USB-C for control and power. iDynamo 5 Gen III products are designed to provide flexible mounting options such as:

• External clip

• Embedded lanyard

See the device installation and operation manual for more information on how to handle and operate the device, [1].

The specified environmental conditions to operate and store the device are:

• Operating temperature range: 32°F to 95°F (0°C to 35°C) 5-90% RH with no condensation.

• Storage temperature range: -4°F to 113°F (-20°C to 45°C) 10-90% RH with no condensation.

• Power Supply: DC 5.0 V/1.0A

Any temperature or operating voltage outside the values listed above will trigger environmental security protections, resulting in a tamper condition. The device will need to be returned to the factory for inspection before this condition can be cleared.

iDynamo 5 Gen III products support a USB-C interface using the USB-HID protocol. Transactions, configuration, firmware updates, and key injection can all be performed using this interface type. Use of any method not listed in this security policy will invalidate the device’s PCI PTS approval.

iDynamo 5 Gen III products ship from the factory fully secure. The devices have no configuration settings that require modification by the user to meet PCI security requirements.

Periodic Inspection

The merchant or acquirer should inspect the appearance of secure card reader on a daily basis:

• Inspect the appearance of secure card reader to make sure it is the right product.

• Inspect whether the Swipe Path has an additional card reader or other inserted bugs, See Figure 4-1, below.

• Inspect whether the product appearance has been changed.

• Check if the firmware version is correct.

• After connecting the device to a USB-C power supply, it will power on, the LED indicator should illuminate green and remain powered on to indicate the device is in an idle state, ready for a transaction. Powering on the secure card reader will test hardware security and authenticity, and the integrity of the installed firmware.

MSR Swipe Path: The swipe path is smooth. The only moving part is the spring-mounted read head that depresses into the device as the card’s magnetic stripe makes contact with the read head.

Figure 4-1 - Card Swipe Path Example

MagTek strongly recommends performing security inspections on a regular schedule. Additional information can be found in [2]. If any problems are detected, stop using the device, set it aside in a secure location, and contact the manufacturer or your acquirer for further advice.

iDynamo 5 Gen III performs self-tests at power-up and after reset. The device automatically resets and performs self-tests every 24 hours at the configured time of day. No manual intervention by the operator is required. Self-tests include:

• Checking the integrity and authenticity of the firmware and cryptographic keys.

• Checking security mechanisms for signs of tampering.

The secure card reader has no functionality that gives access to security-sensitive services based on roles. Such services are managed through dedicated tools, using cryptographic authentication.

iDynamo 5 Gen III products ship from the factory fully secure. The devices have no security related default values (e.g., passwords/authentication codes/certificates) that require modification by the user to meet PCI security requirements.

If the device senses a physical or environmental attack, it erases all sensitive keys and will have limited functionality. While powered on, the SCR indicates it is in a tampered state by illuminating its only LED solid red, as seen in Figure 4-2 Tamper Response. If this occurs:

• Remove the device from service immediately.

• Store it securely for a possible forensics investigation.

• Contact the manufacturer for assistance. The device will likely need to be returned to the manufacturer for diagnosis and servicing.

Figure 4-2 Tamper Response

iDynamo 5 Gen III products support file-based updates of the device’s core firmware (main firmware) and authorized commands for updating sensitive configuration. For optimal device security, MagTek recommends the latest versions of firmware should always be installed.

Firmware updates are provided as files that have been signed by MagTek. The firmware files can be loaded locally through the USB-C interface by using update tools available from the MagTek web site. The device verifies each update is newer than the installed version, and cryptographically authenticates the file with RSA-2048 and SHA-256. If version checking or authentication fails, the device erases the update file and reports an error to the host.

Before iDynamo 5 Gen III products are permanently removed from service, all the keys and sensitive data must be erased. One way to accomplish this is by temporarily removing the back cover, which forces a tamper response.

If removal from service is only temporary, no action is required. All sensitive data will continue to be protected by the device’s physical and logical protection mechanisms.

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

iDynamo 5 Gen III devices include a USB-C interface for Power and Communications, and a magnetic stripe reader (MSR). It is designed for attended and unattended environments.

iDynamo 5 Gen III can be used as a desktop or handheld device. It is approved as a secure card reader (SCR) under PCI PTS POI v6.2 requirements.

Usage in any other environment will invalidate PCI approval.

To find important product identification information, look for the printed product label on the back face of the device as shown in Figure 2-7 below.

Figure 2-7 – iDynamo 5 Gen III Device Label Location

The product label includes the following elements of device identification information, shown by the numbered callouts in Figure 2-8.

• Product Name

• PCI Hardware Identifier (“HW”)

Figure 2-8 -iDynamo 5 Gen III Device Label

The label also contains other supporting information about the device.

The hardware version of the device is 10PCI50U0xAx . All iDynamo 5 Gen III hardware configurations are listed in Table 2-1 below. The device utilizes one interface type, USB-C. Use of any interface otherthan USB-C will invalidate PCI approval.

The most recent firmware versions for iDynamo 5 Gen III products are 1000009547-AAx-PCI for the secure bootloader, and 1000009535-AAx-PCI for the main firmware. The lowercase x in firmware versions indicates minor non-security related changes, see Table 2-3 and Table 2-4.

All device identification information, including firmware versions and PCI Hardware ID, is accessible by connecting iDynamo 5 Gen III to a host device via USB-C using the latest software provided by MagTek, as seen in Figure 2-9 - Device Information Screen.

The host user can retrieve device information at any time using Command 0x0000 Get Property as described in [3].
