Laser Barcode Readers Photo

A barcode scanner is an electronic device for reading barcodes. Most scanners contain decoder circuitry that analyzes the barcode’s image data that is provided by the sensor and sends the barcode’s content back to the scanner’s output port. Laser scanners are the most common type of barcode scanners. They are easy to use, as they do not need to be in direct contact with a barcode in order to read it. A standard range laser scanner will be able to read a barcode from approximately 6 to 24 inches away. A long range barcode scanner will be able to read a barcode from approximately 2 to 8 feet away. There are some extra long range barcode scanners that will be able to read a barcode from approximately 30 feet away.
