Warehouse and logistics managers around the country are using handheld computers to improve operational efficiency. Scanners are built into most handheld computers these days, for obvious reasons, but not all of them have the same capabilities. Consider how far your employees will be scanning barcodes and QR codes if they're required to scan things on the top shelf on a frequent basis, a short-range device won't be very useful. However, Mobile computers with long-range capability could eliminate the need for moving steps, saving time and space in the warehouse. The ultimate purpose of inventory management is to optimize supply chain procedures in order to reduce costs while maintaining customer service.
