just don't call it "finger printing"
Picture this: You've spent the afternoon filling up a shopping cart with things you want to buy. You pull up to the checkout line, and realize that you've left money, debit cards, and credit cards at home. Do you abandon the cart? Ask someone from the store to keep an eye on it while you rush home to get some cash or a card? Or do you just put your index finger on a finger image reading pad, and your purchase is complete?
A couple of Kroger stores in Texas are experimenting with letting people use finger image technology to make purchases. They don't like using the term finger printing because of the law enforcement image it evokes. Is this a wave of the future? They do have 10,000 participants, but it is still in the testing phase.
