BioPay LLC, a Herndon company that sells biometric technology that allows consumers to pay for goods by scanning their fingerprints, agreed to be acquired by San Francisco rival Pay by Touch for $82 million in cash and stock.What will these companies will do with that huge databank of personal information?

Pay by Touch will take over all of BioPay's retail customers, as well as its database of consumers and portfolio of patents.
