Barcode scanners or barcode scanners are electronic devices used for reading printed labels. These devices consist of light source, light sensor and translating lens, the eyepiece impulses into electrical impulses.

PDA (Personal Digital Assistant) scanner has an integrated barcode scanner or a connected barcode scanner. A good example of this scanner is the Grabba. It is a useful accessory to your PDA device.
