The NADAMOO BUR3147-2 is a wireless 2D barcode scanner made for retail, inventory, warehouse and small business use. It reads standard 1D barcodes and 2D codes like QR codes and PDF417, on printed labels or right off a phone or computer screen. The USB wireless receiver gives up to 66 feet of range indoors and up to 328 feet in open areas, and it can also plug in directly by USB cable. When you are out of range, offline mode stores up to about 10,000 barcodes and uploads them later. Use it by hand with the trigger, or set it in the included adjustable stand for hands free auto sensing scanning. It works with Windows, macOS and Linux and runs on a rechargeable battery.
