I read elsewhere that some debit/credit cards store transactions details on them. So I got out my phone and downloaded some free card reader software, and I discovered that two of my cards did in fact store transaction details that could be read contactlessly. One was my TransferWise card, and the other was my Starling Bank card.
The details revealed are just date/time and amount (not the retailer), but they could be read by contactlessly or by a card terminal and so I wondered if there is some reason for storing the details on the card?
I have mentioned this a couple of times in another forum, but nobody came forward with a reason why it might be decided to store transaction details on the card. I haven’t been able to find any information about this online either (maybe I’ve looked in the wrong place) and Starling Bank haven’t got back to me on this yet when I asked them.
