Scanners are used to read printed barcodes and send the information to a computer. They are largely used in warehouses for inventory and stock purposes.
Scanners are easy to use, lightweight devices that are affordable and efficient. They are used to capture data & information automatically via the scanning of a barcode. That information is then sent and input into a computer system.
The process is simple but speeds up processes and reduces the risk of input errors – hence why it is so widely popular in fast-paced warehouses.
