Some gasoline purchasers in Chicago can now purchase gas using fingerprint scanners installed at pumps and cash registers at Shell stations. Customers will have their fingerprints scanned at a machine inside the station and then can purchase gas by swiping their finger, rather than a credit card. One store manager said "I think it scares people. They're more confused about the whole system. Some of them say, 'Well, now the FBI can find me.'" We doubt the FBI will be on their tail, but at least they can still buy gas with cash, unlike iPhone purchasers. [AP]
