What is a "virtual visa card"? - dpb
It's a service that generates a set of Card number + expiration date + cvv2 for each transaction. The merchant operates with that set as with any other. The service responds as expected as long as there is no change of merchant or transaction id and a transaction limit value is note reached. One gets one new set for each transaction.
