Online transaction - Money taken out late
Debit Cards have a certain processing delay, "lag time", before the transaction from the vendor completes with your bank. In the US it's typically 3 business days but I have seen even a 15 day lag from Panera Bread. I guess in the UK, payment processors have similar processing delays. A business is not obliged to run its payment processing in realtime, as that's very expensive. Whatever be the lag time, your bank is supposed to cover the payment you promised through your card. Now if you don't have agreements in place (for example, overdraft) with your bank, they will likely have to turn down payments that exceed your available balance. Here is the raw deal: In the end, the responsibility to ensure that your available balance is enough is upon you (and whether you have agreements in place to handle such situations) So what happened is very much legal, a business is not obliged to run its payment processing in realtime and no ethics are at stake. To ensure such things do not happen to me, I used to use a sub-account from which my debit card used to get paid. I have since moved to credit cards as the hassle of not overdrawing was too much (and overdraft fees from banks in the US are disastrous, especially for people who actually need such a facility)
