The Datalogic QuickScan QM2131 barcode scanner is ideal for retail, inventory management, document processing, packaging, and other applications where traditional codes dominate and area imagers often reach their limits due to lower depth of field. The QM2131 combines an extra-long field of view with a long scan line, allowing it to easily capture long barcodes at close range. An enhanced decoding library ensures very fast barcode reading. The connection to the base station is wireless on the 433 MHz frequency band with a range of up to 25 meters. This has the advantage of not interfering with existing Wi-Fi infrastructures and being minimally affected by obstacles such as concrete walls or metal shelves. In case of a faulty connection, up to 500 linear codes can be buffered internally in batch mode. It can even operate completely without a charging station: the micro-USB connection allows not only for charging the battery but also for operation in host configuration.
