• 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.
