"It seems to be that designer Seokmin Kang intends the Finger Scanner to be used by customers and cashiers alike. This innovative device is a compact barcode reader that can be used to clarify product prices, and to ring in items upon their purchase.  The sleek piece of technology slips easily onto a person&amp;#039;s fingertip and is free of any bulk. It combines a sensor that can scan tags and labels in just two seconds, as well as a digital display panel to show the cost. It&amp;#039;s easy to carry and put on when you&amp;#039;re shopping, and the Finger Scanner can be conveniently used with your hands full. Just shift your hand over the sticker and the information will register."^^<http://www.w3.org/2001/XMLSchema#string>
