A barcode reader is an optical scanner that can read written barcodes, decode the information in the barcode, and send it to your computer for analysis. A typical flatbed scanner contains a light source, an eyepiece, and a light detector for detecting components translating the electric signals into optical ones. Truck drivers or inventory clerks often use these devices to determine the stock level in their storage areas or locate items on pallet racks. Manufacturers can also use them to determine where to place products on shelves.
Before purchasing a barcode scanner for your needs, it would be a good idea to study how such devices work and what they are capable of. There are many types of scanners available out there, ranging from hand-held devices to sophisticated industrial ones. If you are searching for a barcode reader that can be used in your business, then the most logical choice for you would be one that can be connected to your company network and networked through the Internet.
