3 results about "Smart card security" patented technology

The security of a smart card system consists of the front-end enforcement, front-end and back-end verification, back-end audit and system fraud damage control. Security is addressed at the system level. Technically Mifare cards can be emulated. However if the system security design is correct, fraud is only possible with a collaborating cardholder or merchant. It is improbable that a merchant would accept a payment with the cardholder carrying a big emulator to pay for the transaction.
