They're sugary, adorable, and capable of foiling advanced security systems: A Japanese researcher has found that the gelatin used in Gummi Bears can also be used to make fake fingers that fool biometric fingerprint scanners. The research also found that it's a simple matter to lift a fingerprint from a glass, photograph it, and then imprint it onto a mold to create a duplicate fingerprint. This follows a study last year that found Play-Doh worked equally well. So much for plans by large retailers like Wal-Mart and Costco to let shoppers pay for purchases by scanning their fingers at the register.
