Can't remember which one but credit cards were offline for a time with something and places that still had the carbon paper roller things stashed away took them out and used them. They should keep those things around.

    Serious privacy issues around copying cards. That means the store has to retain a physical copy of the full embossed card number.

    There were boxes full of them in the backroom.

    Do people still have embossed credit cards? All mine are flat now.

    That's against the rules for PCI compliance

    Under no circumstances should you copy a card

    Shop I worked for in 2005… I think … ran cards when the connection was down and took card impressions, and I think the transactions were all auto submitted when the connection came back up.

    national chain. I think it stored the transactions for transmission, and in-case it didn't go through we also had the imprints as proof of having the card at the time of transaction. I assume it processed them as a different option instead of instant approval, and probably has different liability implications if the transaction is later denied. Being a big company, was probably fine.

    Not sure how much good that'll be... A lot of banks are giving out cards where the numbers are only printed, I haven't had one with raised numbers in years.
