product that scans barcodes with a laser. They work on short distances and don't give fully out of type of sight-reading. AKA barcode scanner or scanner.
computer that scans a barcode by shining a laser beam on it. Barcode visitors (unlike magnetic-stripe visitors) tend to be 'non-contact' automatic data capture products, operate just at quick distances (several ins), and (unlike in radio frequency recognition) try not to provide 'out of distinct sight' reading. Also referred to as barcode scanner or perhaps scanner.
