CMU Students Show Fingerprints May Be Way to Buy

In the age of the Google Wallet and PayPal, the use of fingerprints as a payment method doesn’t seem implausible. And the idea wasn’t for Umang Patel and three other Carnegie Mellon University students who recently launched their own biometrics-based pay system as an alternative to plastic credit.
With PayTango, a swipe of the finger links users’ personal information to their credit or debit card in less than 15 seconds, making for a quick and easy-to-use system.
