Driver card not recording?

You didn’t put it in slot 2 did you by mistake

I’m pretty certain that would flash up a driving without card error.

This does indeed flash up card error. In defence of the driver I have tried my driver card every way up in both slots. On all occasions it is obvious the card is not where it should be.
All our cards are downloaded weekly, its only when i have downloaded the head data that the analysis software identified the unaccounted miles.

It looks like an open and shut case of driving deliberately without a card in, but I just want to eliminate any possibility of a card fault, which is the only remaining possible alternative, before proceeding with the driver.

It’s sad that your now put in a position now of what to do with driver , but it’s your O licence you’ve got to protect
I do hope for both parties it a faulty card
