I need to be able to capture credit card details over the phone and store securely in an Access database. The requirement is to then create an extract file containing credit card details, amount and to be sent to a bank. If the same customer calls again weeks later, there is a need to be able to re-use the same credit card. Any suggestions for how best to do this? Can it be done within Access only or do I need to consider some external service to which I should interface?
