A barcode scanner is an electronic device for reading barcodes. Most scanners contain decoder circuitry that analyzes the barcode image data provided by the sensor and sends the barcode content 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 about 6 to 24 inches away. A long range barcode scanner will be able to read a barcode from about 2 to 8 feet away. There are some long range barcode scanners that will be able to read a barcode from about 30 feet away.
A decent handheld laser scanner will start at about a hundred and fifty dollars. Some scanners offer exceptional speed and accuracy and are also quite durable. They offer exceptional performance even in harsh environments.
Laser scanners consist of a laser and a photodiode (a type of detector that converts light into voltage or current) that are placed side by side at the tip of a wand. They have an alternate mirror or rotating prism that scans the laser beam from one side of the barcode to the other.
Many industries use laser barcode readers; retail establishments, healthcare establishments, laboratories, libraries, and are used for document management, parcel and correspondence tracking, and even for the issuance of tickets. These readers offer accuracy and visibility as they can read a barcode at any angle. Laser barcode scanners are capable of reading longer, lower-density barcodes and have longer scanning distances than less expensive LED or CCD scanners. Most barcode readers are easy to install and use.
