USB (Universal Serial Bus) Barcode Scanners use the USB port of a PC computer to transfer or synch data that is captured. USB Barcode Scanners are the most common technology that can transfer data at up to 12 megabytes/second, can be daisy chained (with up to 127 devices on a single port) and can provide power from the computer's power supply to peripherals (so that peripherals do not need their own AC power). USB "hubs," boxes that provide multiple USB ports and a power boost to the USB chain are usually needed if you have more than a few USB devices on your machine. USB also allows hot-plugging so that you can plug and unplug your scanners without having to shut down your computer.
