Security measures for credit card

摘要

A method for generating a code on card related transactions such as credit card transactions includes loading multi-factor authentication software onto the card itself. The software is read by a card transaction terminal such as an ATM or a similar payment station which generates a time and/or date specific code which is verified with a code generated on a remote CPU running similar or identical multi-factor authentication software. The two codes need not be identical, but should be similar to a sufficient tolerance to ensure that there is no security breach. Once the code is verified the transaction may proceed as it would normally.
