FORT WORTH, Texas -- The future is here, we've seen it in the movies. And now, that futuristic technology has made it all the way to your local grocery store.

No longer will you have to take the time write out a check, or even swipe a card. In fact, you can leave your wallet at home, using only your fingerprint to pay for your groceries.

Kroger calls it "Secure Touch And Pay," a way to purchase your groceries using only your index finger.

About 10,000 people regularly use this finger imaging program.

Using your driver's license, it just takes a few minutes to sign up, and then all it takes is a touch of your finger.

Customers who enroll choose a type of payment they want to use, a credit or debit card, or their checking account. They have their index finger scanned, and use it from that point forward as the fingerprint is associated with your banking preference.

Kroger is now testing the program in three stores in College Station, Texas to see how well this technology works and if it's cost effective for the company.

Some people have expressed a concern about big brother or infringing on law enforcement's use of the fingerprint identification. But Gary Huddleston with Kroger says that the program is voluntary, and they use the index finger, not the thumb for a print. "Its no connection to law enforcement. No connection with the government," Huddleston said.

"I think it's really neat. And I will probably get there at some point. I'm just not ready to use it yet," shopper Kris Clark said.

Kroger started the program last summer, but won't discuss how much the technology costs. The company says that early indiciations are the program will cut time it takes to pay for your purchases in half.
