barcode reader (BCR)

Bar code readers, bar code scanners or laser sc anners are peripheral devices for personal computers(PCs) and data processing systems that convert the bar code into bit-serial signals. In this conversion, the sequences of narrow and wide gaps and bars are scanned by light reflection and the corresponding bar code is converted into a value.

In addition to the stationary cable-connected barcode readers and handheld scanners, there are the wired and radio-based reader pens, which are particularly suitable for mobile use and for scanning the barcode on bulky goods or pallets. The radio-based reader pens work with Bluetooth or a radio base station that is connected to the computer.

Barcode scanners differ in design and in the number of barcodes that can be read. Barcode reader embodiments include handheld scanners, slot readers, laser-guided scanning device such as the reading gun, and the reading pen.

Readers for 2D codes are referred to as imagers or 2D code readers.
