For Driver Identification: Choose an appropriate location to mount the NFC reader using the provided dash mount, or the optional window mount SPR-NFCBRKTV2ASY.

NOTE: Ensure the installation does not interfere with the safe operation of the vehicle, and check that you have sufficient cable length before mounting.

The NFC Reader includes a mounting bracket that is to be screwed in place (screws provided). The provided tape is used to position and hold the bracket prior to permanent mounting with screws.

The optional window mount bracket (SPR-NFCBRKTV2ASY) is provided with dual-lock tape. Before mounting, clean the window with an alcohol wipe and a dry cloth.

NOTE: The provided tape is NOT a permanent mounting solution. Screws must be used to complete the installation.

For Keyless: We recommend separately purchasing SPR-NFCBRKTV2ASY to front-mount IOX-NFCREADERA to a vehicle windshield.

Determine the best location to mount the SPR-NFCBRKTV2ASY.

Typically, the lower corner or bottom of the windshield is a favorable location. The mounted IOX-NFCREADERA should not obstruct the driver's view, and the cable should be positioned so the cable run can be easily concealed behind the A-pillar covering, and routed to the GO device, without adding stress or pressure on the bond to glass. Avoid high angle radius bends to the cable.

Ensure the placement of the SPR-NFCBRKTV2ASY, or IOX-NFCREADERA cable, will not interfere with airbag deployment.

Prepare the windshield mounting location by cleaning the area with an alcohol wipe and then wipe clean with a clean, dry cloth.

Secure the dual lock tape on the SPR-NFCBRKTV2ASY, and then with the IOX-NFCREADERA securely seated in the bracket, firmly seat the IOX-NRCREADERA and SPR-NFCBRKTV2ASY to the windshield and hold for 30 seconds.

Use cable ties to complete the installation by routing and securing the cable, and connecting the IOX-NFCREADERA to the GO device.


Once you connect the IOX-NFCREADERA to the GO device, plug in the GO device and start the vehicle. The GO device enters debug mode.

Secure the IOX-NFCREADERA/GO device connection with a cable tie, and then secure the GO device to the vehicle with two cable ties. Ensure the GO device cannot vibrate or move, and that the serial number is visible and facing away from where it is mounted.


To test the NFC Reader installation, touch a valid NFC Tag (listed above) to the reader.

For Driver Identification, the green LED on the reader flashes twice and the GO device emits a single beep when the tag is read. Repeat this step for each additional tag.

If a Driver ID Relay is installed and the feature is active in MyGeotab, you must swipe a valid ID tag to activate the relay. Failure to activate the relay, prior to use, causes the GO device to beep continuously and the electrical connection, driven by the relay, remains inactive until a valid key tag is swiped on the reader.

For Keyless, the LED will flash green, then flash continuously.

    Termination shunt

    The IOX comes with a termination shunt installed in the expansion port. If you plan to install more than one IOX in a daisy chain, you must remove the shunt from each device in the line, with the exception of the last IOX connected. The shunt must remain in the last IOX and secured with a zip tie.

    The shunt in the last IOX device ensures the GO device detects and configures the IOX as effectively as possible.

    NOTE: Failing to install the shunt in the last IOX could affect IOX communication. It is recommended that you secure the shunt using a zip tie if not already done.


    The IOX-NFCREADERA cannot be used in conjunction with the IOX-HID (Discontinued)

    Using NFC: Driver Identification

    Driver ID authlist

    To create an authlist of authorized drivers for a particular GO device, apply the following custom parameter to the GO device through MyGeotab:

    <Parameter Description="Enable Authorized Driver List" Offset="164" Bytes="8" IsEnabled="true"/>

    Once the parameter is applied, the IOX-NFCREADERA only accepts driver key tags assigned to an authorized driver. You can add and remove drivers to/from the authlist through the Geotab API ( See the DriverAuthListContent object for more details.

    The authlist mode is disabled when the custom parameter is removed from the GO device.
