I have blank NFC cards I would like to use for geotab along with employee ID cards. I'm not sure how to write the driver ID to the card. Does anyone have any examples. I have the NFC reader installed and the following added under the vehicles for custom parameters  &lt;Parameter Description='NFC use Generic Card Serial Number' Offset='179' Bytes='01' IsEnabled='true'/&gt;

Ok, I think I figured it out. I didn't need to write anything to the NFC card. Each card has it's own unique serial number. In this case the number on the card I was using was 04:78:A5:E2:A2:71:81 I had to convert the Hexadecimal to a decimal. I used this website https://www.rapidtables.com/convert/number/hex-to-decimal.html and entered the hex number. It converted the hex number to 1258553774076289. I put this new number as my driver ID and it works. I now get assigned to a vehicle when I badge in.  The disadvantage to having the &lt;Parameter Description='NFC use Generic Card Serial Number' Offset='179' Bytes='01' IsEnabled='true'/&gt; on the vehicle is you can swipe any NFC and it will turn off the beep notification since the reader will now read any generic nfc and not just the geotab. It will list the driver an unknown driver if the serial number is not assigned as a driver.

Thanks, I used the program NFC Tools. I wrote a text with the ID but I'm sure that wasn't correct.
