Jewel-Osco, a Midwest supermarket, introduced a biometric payment system. After signing up and associating your fingerprint with your credit card, you can buy groceries just by pushing your finger on a reader at checkout and entering your "search number."

According to their FAQ, this information is secure, they don't actually take your fingerprints (just "data points...which cannot be turned into a fingerprint), and all the information is stored off-site at a Pay-By-Touch facility, a privately held company.

What do you think? Is this more, or less, secure than current systems of payment and authentication?
