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.

My friends and I used to call those machines ker-chunkers. 😂

Knuckle-buster was the industry term, and they were already obsolete 20 years ago...

I've heard it mentioned as a "fly swatter" in my mother's tongue.

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

[–] HubertManne@moist.catsweat.com 3 points 4 months ago (1 children)

good point. I think embossing went away about when wireless became ubiquitous with it. So they would need to be doing that again.

My card is embossed. Then again it's also from a community credit union in southeast Michigan. Lol.

That's against the rules for PCI compliance

Under no circumstances should you copy a card

[–] HubertManne@moist.catsweat.com 1 points 4 months ago (1 children)

are they not allowed now. The thing im thinking about was definately post 2000 but maybe not 20teens

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.

[–] HubertManne@moist.catsweat.com 1 points 4 months ago (1 children)

did they do something special. most places I have been to when the network is down it just does not work.

[–] Truck_kun@beehaw.org 1 points 4 months ago

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.

[–] fine_sandy_bottom@discuss.tchncs.de 1 points 4 months ago (1 children)

You could just write down the numbers.

[–] Malfeasant@lemm.ee 1 points 4 months ago

You could, but then we wouldn't be talking about a carbon paper roller thingy...
