Ready-to-use barcode reader

The bitmain MK7120-31A38 is a new barcode scanner supplied with a USB cable for immediate connection to a host system. It is intended for retail, warehouse or office staff who need a simple plug-and-scan device without additional drivers or power adapters.

Wired USB simplicity

The included cable provides both data and power, so the scanner draws no separate supply and adds no desk clutter. A fixed cable means the unit stays tethered to the workstation, which suits stationary checkout lanes or inventory stations but limits reach to the cable length provided.

Low-power, quiet operation

With no moving parts and only the USB bus to power the imager, the scanner runs silently and adds negligible load to the host port. Normal use produces no audible fan noise and minimal heat, making it comfortable for continuous scanning shifts.
