To get cash out in the 21st century, you won’t need a bank card, a PIN(个人识别编号) or even have to move a finger. You will simply have to look the cash machine straight in the eye, declares National Cash Registers, a multinational company that makes automated teller machines, or ATMs. NCR has shown its first example machine that is believed to be the future of banking. Instead of asking you for your PIN on a screen, the Super Teller-Stella for short, asks you orally through a loudspeaker to look straight ahead while an infrared camera turns to your head, then your eye, and finally takes an infrared photograph of your iris(虹膜). For identification(识别) purposes, an iris picture is better than a fingerprint, with around 256 noticeable characteristics compared with 40 for fingerprints. This means that the chances of someone else being recognized in your place is about 1 in 1020. Once you’ve been identified, Stella greets you by name and says: “Would you like cash or a statement?” An infrared port allows the machine to send a bank statement straight to your pocket computer.
