The 411 - Barcode Scanners

Barcode scanners work by using a light source, usually a laser, to read the barcode and then converting the barcode into digital information that can be interpreted by a computer or other device. Here are the basic steps of how a barcode scanner works:

1. The scanner is activated and a light source, such as a laser, is emitted.

2. The laser scans across the barcode, reading the bars and spaces.

3. The reflected light from the bars and spaces is picked up by a photosensor in the scanner.

4. The scanner converts the pattern of light and dark bars into a digital signal.

5. The digital signal is decoded by the scanner's decoder circuitry, which converts it into a readable format.

6. The decoded information is then sent to a computer or other device, where it can be used for inventory tracking, price lookups, or other purposes.

Some barcode scanners may also have additional features, such as the ability to scan multiple barcodes at once or to read barcodes from a distance. However, the basic process of using a light source to read the barcode and converting it into digital information is the same for most barcode scanners.
