'"Cards" in the java-card-OS are cryptographically "personalized" by the payment network (VISA, AMEX, MasterCard) with per-device keys and the device personal account number (DPAN)--the tokenized device only credit card.'
Is this 'tokenized device only credit card' the same concept as the Point-of-Sale seeing a unique CC # (generated) for the transaction? (What I believe is one of the selling points for Apple Pay). Are there other products that do this?
