Now, pay using your fingerprints instead of debit or credit cards

An average user carries dozens of credit or debit cards with him or her. However, if a new system called PayTango gets accepted, you will just need your fingers to pay for any transaction. Designed to replace credit card terminals at retail stores, the startup founded by four Carnegie Mellon University students, and backed by YC Combinator, PayTango links cards to your fingerprints.

Here is how it works. A customer simply places his index and middle finger on the biometric scanner on the PayTango terminal which is linked to a merchant's point of sales system. If the user is registered in PayTango, the system recognizes the fingerprint, and completes the transaction. PayTango says that any card with a magnetic stripe can be registered.
