TECHNIQUES FOR SECURE CREDIT CARD TRANSACTIONS

摘要

A consumer registers a credit card at a point-of-sale device for additional security. The point-of-sale device does not require the additional security for processing credit card transactions. Subsequently, when the consumer presents the credit card at the point-of-sale device for a particular credit card transaction, the additional security is provided by the consumer and verified before the credit card and the particular credit card transaction is permitted to be sent to a card processor associated with the credit card.
