barcode scanner (A barcode reader (or barcode scanner) is an electronic device for reading printed barcodes. Like a flatbed scanner, it consists of a light source, a lens and a light sensor translating optical impulses into electrical ones. Additionally, nearly all barcode readers contain decoder circuitry analyzing the barcode's image data provided by the sensor and sending the barcode's content to the scanner's output port. WK Alexander Demidov); barcode reader (Electronic device that scans a barcode by shining a laser beam on it. Barcode readers (unlike magnetic-stripe readers) are "non-contact" automatic data capture devices, operate only at short distances (a few inches), and (unlike in radio frequency identification) do not provide 'out of line of sight" reading. Also called barcode scanner or just scanner. BD Alexander Demidov) |
