biometric payment? never heard of it before...

I think it works by replacing a Credit Card with your fingerprint or anything unique to you.

So you would just press your finger against a machine to pay for something instead of having to use a credit card.
That's what i THINK anyway...

Biometric payment is a point of sale (POS) technology that uses biometric authentication to identify the user and authorize the deduction of funds from a bank account. Fingerprint payment, based on fingerscanning, is the most common biometric payment method. Often, the system uses two-factor authentication, in which the finger scan takes the place of the card swipe and the user types in a PIN (personal ID number) as usual. Here's an example of how one fingerprint payment system works:

• The shopper registers for a biometric program at a store kiosk by presenting valid identification and bank account information.
• The shopper scans his index finger using the kiosk's fingerscan reader.
• The store's fingerscan reader encrypts multiple point-to-point measurements of the fingerprint and stores the customer's biometric data and banking information in a centralized database.
• The shopper now has the option of selecting biometric payment at the point of sale register. If he chooses biometric payment, he scans his finger at the checkout register with the store's electronic reader and enters his personal identification number.
• The electronic reader compares the data from the new scan to the encrypted data in the database and either approves or declines the transaction. If approved, the funds are electronically transferred from the shopper's account to the merchant.
