Re: Payment terminals
I was wondering that myself, why does the PoS computer even need to know the credit card number? Surely you just send the price to the card terminal, and receive back a message either telling you that the customer's card paid up, or that it didn't (or was cancelled, declined etc.)?
This way not only is your PoS terminal not at risk of CC numbers being leaked, but you don't have to worry about PCI compliance for your PoS software, which is a massive advantage.
