As a wearable scanner the IS4200 mounts easily and comfortably to the back of an operator's hand. By mounting the scanner to the back of the hand and connecting to a portable data collector the operator is not restricted and can freely move about. The scanner reads bar codes automatically as the operator presents the scanner to the code. Whether used for order picking, shipping and receiving or inventory control, this simple scanning movement will undoubtedly provide increased flexibility for the operator and ultimately increased productivity. The IS4200 scanner is available in two models: IS4210 is the non-decode model and the IS4220 has built in decoding for applications that use a RS232, Keyboard Wedge, Stand Alone Keyboard or Light Pen Emulation communication interface.
