No, they don't need the card at all. Proof of purchase will suffice, and they can actually find the exact purchase using the client's phone number or email. And even if there is no proof of purchase, they can send pictures of the bag to the repair center and they can assess the bag.Thanks for the reply, AJ! Does that mean the card serial number would tally with the data chip? Yet it isn’t that important after all if I send a bag in for service or repair since the data chip will be able to tell all the information? I’m just worried that I may send in a bag with a wrong card!
