The Baracoda RoadRunners BRR-FS Evolution is a portable wireless 2D barcode scanner built for warehouse, inventory, retail and field work. Its full imager reads both standard 1D barcodes and 2D codes like QR codes. Class 1 Bluetooth reaches up to 330 feet under ideal conditions, so you can scan across a large stockroom without staying near the computer. When you are out of range, it stores up to about 10,000 barcodes and uploads them later. The rechargeable lithium ion battery keeps it working through the day in a compact, lightweight body. It connects by Bluetooth 2.0, so please confirm your computer or device is compatible before buying.
