An RF scanner, or radio frequency scanner, is an electronic device used to automate data entry of physical items into databases or computer systems so they can be logged, tracked, and managed. RF scanners are handheld devices that read barcodes and transfer product information, quantities, and location information directly into the warehouse management system (WMS) via wireless networking. They are used for almost all warehouse operations, from receiving to picking/packing and finally shipping. Some common uses for RF scanners include:

• Picking
• Packing
• Shipping
• Communication between different scanners
• Communication between technology systems throughout the warehouse
• Goods receipt
• Rigorous stock control

There are different types of RF scanners, including laser scanners, fixed-mount scanners, and vehicle-mount scanners. Laser scanners are the most basic and common type of RF scanner, using light from a laser beam to shine on barcodes. Fixed-mount scanners are designed to scan items or materials automatically at high speeds, making them perfect for keeping up in fast-moving manufacturing applications. Vehicle-mount scanners are mounted on forklifts or other vehicles and are used to scan items as they are moved around the warehouse.

RF scanners are essential to most facilities, and they do a lot of work that would have otherwise likely been done manually. They provide a paperless option, offer more accurate picking, and there is less room for error due to the immediate results shown on the scanner.
