What is pick by scan?

With pick by Scan, the picker works with the help of so-called mobile data capture devices, also known as barcode scanners. This technology is popular not only in warehouse environments, but also in the retail sector due to its flexibility, low susceptibility to picking errors and a virtually non-existent training period. However, the disadvantages include limited freedom of movement and the initially high acquisition costs of the hardware.
