Exactly like that most likely, I am old enough to remember those machines where credit cards left their mark on the receipt, that is why their numbers are higher than the card. Here, https://en.m.wikipedia.org/wiki/Credit_card_imprinter
We did sailing charters growing up and had one of these on the boat, I was in charge of it and the sound & feel of the CH-CHUNK is seared into my memories like nothing else. We never got any declines, but I always wondered how that reconciliation process actually worked out.
If you mean chargebacks: I believe imprinters had card issuer liability for the longest time, at least as long as the transaction was under the (network-defined) "floor limit".
So if these were relatively low value transactions, the bank would simply not have any standing to decline payment.
