The Baracoda RoadRunners BRR-L Evolution is a compact wireless barcode scanner built for warehouse, inventory, retail and field work. Its Class 1 Bluetooth reaches up to 328 feet, so you can scan across a large stockroom without staying near the computer. When you are out of range, batch mode stores up to 20,000 UPC codes in memory and uploads them later. The Intermec EV10 scan engine reads up to 200 scans per second from about 1.5 to 19 inches away, and the 2200mAh rechargeable battery charges fully in about 4 hours. It connects by Bluetooth SPP, which works with most Windows computers and Android devices; please confirm your device supports SPP before buying. This is a 1D scanner; it reads standard linear barcodes like UPC and Code 128, but it cannot read QR codes or other 2D codes.
