Your card limit gets checked on every transaction. There doesn't seem to be a technical reason why information flow back to me should be limited in any way. If the extra layer fails to work the transaction fails to pass.

The merchant can choose the level of verification - in some cases, like copying the card with an imprinter [1] or running phone transactions (yes, that is possible - it's called MOTO [2]), it's obviously impossible to check card limits. Downside of CNP transactions is, the merchant is fully liable for anything from fraud over chargebacks to exceeding limits. And then you got card-present transactions but the network connectivity is down for whatever reasons... been a while since I messed with that, but at least for German cards you could configure the terminal to store the account details for later submission when connectivity was restored.

- ErneX 2y agoI remember being charged after a while when paying for bus/metro tickets in some places, I think those machines process transactions by batches or something.
