  • Page 4 The VTAP50 equipment is intended for use by suitably qualified integrators, who will integrate the VTAP50 OEM module (PCB) into their own hardware, without any changes or modifications to the VTAP50 OEM module device. (An optional enclosure can be supplied.) Components mounted on the VTAP50 PCB are not user-serviceable.

  • Page 7: Using This Guide

    VTAP50 unit, when a new release is available. The firmware on a VTAP50 functions in exactly the same way as that used on a VTAP100, so you can refer to generic VTAP Configuration Guides.

  • Page 8: How The Vtap50 Works

    VTAP100, so you can refer to generic VTAP Configuration Guides. By default the VTAP50 is fully upgradable in the field. However, the VTAP50 can be locked in software or hardware, before deploying the unit, so that operation is no longer easily changed.

  • Page 9: Default Operation

    These steps demonstrate that the hardware can detect and interact with an OriginPass demo mobile NFC pass, which is ready to work with the default configuration of your VTAP50. 1. Obtain an OriginPass from Dot Origin by visiting https://originpass.com/VTAP/ and add it to Google or Apple Wallet.
  • Page 10 VTAP Application Note which explains more about ECC key pairs and how to generate your own keys.) This first time, you will need to connect the VTAP50 to your PC, using a USB cable. (If needed, you can make changes remotely in future over a virtual COM port or serial port, see VTAP Serial Integration Guide.)
  • Page 11 (There is a VTAP Application Note on Multiple Passes which explains more.) Put each parameter on a new line. Order of parameters does not matter to the VTAP50, but could help other people who need to edit the file. Start any comment lines in the config.txt file, that the VTAP50 should ignore, with a semicolon.
  • Page 12 Note: If an ST#KeySlot parameter is omitted, or set to 0, then authentication will be omitted and decryption will not be performed. In this case, Google Smart Tap data will be received and sent on by the VTAP50, only if the pass does not require authentication by the terminal.

    VTAP MOBILE WALLET READERS 2.3 Check status in BOOT.TXT If you navigate to the VTAP50 in the computer's file system. It will appear as an attached mass storage device and list the files contained, including the BOOT.TXT file. Inspecting BOOT.TXT will give you essential information about your VTAP50 set up, at time of last reboot, which might be helpful when troubleshooting.

    VTAP MOBILE WALLET READERS 3   Mechanical installation The VTAP50 unit for OEM integration comprises a PCB with an integral antenna around the perimeter of the board. Figure 3-1 VTAP50 components - v1 or v2 Hardware WARNING: Observe all Safety instructions when installing the VTAP50 PCB.

  • Page 16: Mounting Points

    The PCB has 2.7mm diameter mounting holes for fixing the unit. Use 2-4 small nuts and bolts to mount the board securely. Figure 3-2 VTAP50 PCB mounting holes - v1 or v2 Hardware The user’s smartphone should be able to tap within 10mm of the antenna on the PCB. The antenna position should be clearly marked and easily accessed, so that users can position their smartphone appropriately.
