### Product Type <a href="#ref72489950" id="ref72489950"></a>

All DynaFlex II Go products include USB communications, a magnetic stripe reader (MSR), a contact chip card reader (ICCR), a contactless card reader (CTLS), and may also be purchased with an embedded barcode reader (BCR) and Bluetooth LE connectivity.

DynaFlex II Go models can be used as desktop or handheld devices.  They are approved as a secure card reader (SCR) under PCI PTS POI v6.2 requirements.

Usage in any other environment will invalidate the approval.

#### 1.1.1     Firmware Identification <a href="#ref20818897" id="ref20818897"></a>

The most recent firmware versions for DynaFlex II Go products are 1000009446-AA0-PCI for the secure bootloader (Boot1 FW), 1000009421-AC0-PCI and 1000009714-AC0-PCI for the core firmware (Main FW), and 1000009327-AA0-PCI for the Bluetooth LE Firmware Version. The X in firmware versions indicates minor non-security related changes.  The secure bootloader firmware version also covers the initial bootloader (Boot0) permanently programmed into the device.  Any changes to either Boot0 or Boot1 will result in a change to the Boot1 FW version that is visible to the user, reported by the device, and listed on the PCI Approved Devices website.

All device identification information, including firmware versions and PCI Hardware ID, is accessible by connecting DynaFlex II Go to a host device via USB or Bluetooth LE, using the latest software provided by MagTek, as seen in Figure 2‑6 - Device Information Screen.

The host user can also can retrieve device information at any time using Command 0xD101 Get Property as described in DynaFlex II Go Programmer’s Manual (COMMANDS).
