Answer / keval bhatt
Point-of-sale terminals that use magnetic-stripe cards and
PIN codes have a fatal flaw: a malicious merchant can modify
his card reader to capture and store all the information on
the card as well as the PIN code in order to post additional
(fake) transactions in the future. The next generation of
point-of-sale terminals will use cards with a complete CPU,
keyboard, and tiny display on the card. Devise a protocol
for this system that malicious merchants cannot break.
