New High-Tech Credit And Debit Card With More Security

Saturday, September 18, 2010 - 6:41 AM
From the Technology Review:
A programmable credit card can display useful information, offer added security features, and even act as several different cards by rewriting its own magnetic strip.

This could be handy for those who carry multiple reward checking debit cards. Not only will it cut down the number of cards that you carry, but it will also reduce the risk of loss if you lose your wallet.

The weakness for this type of smart cards is the "single point of failure."  If the card is lost and in the hand of "expert", who can decipher the code, it will be "multiple cards" at risk.
