Barcode Scanners

A 1D scanner reads traditional linear barcodes (e.g. EAN, Code 128), while a 2D scanner also reads QR codes, Data Matrix and other two-dimensional codes. 2D scanners are backwards compatible, reading all 1D codes too, and from any orientation. For new purchases we generally recommend 2D, as prices are now close to 1D and it is future-proof.

This requires imager technology, typically a 2D scanner – traditional laser scanners read on-screen codes unreliably or not at all. For mobile coupons, digital tickets and e-invoices we therefore always recommend an imager scanner.

By default no: scanners present themselves to the computer as a keyboard and type the scanned code wherever the cursor is – so they work instantly with any program, webshop or enterprise system. Special integration (e.g. serial port, SDK) is also possible, and we can assist if needed.

For fixed workstations (checkout, packing desk) a corded scanner is the simpler and cheaper choice, with no charging to manage. If the worker moves around or large items must be scanned, a Bluetooth cordless scanner is more convenient – depending on the model, the range typically extends from 10 metres up to several tens of metres, with the actual distance also affected by the building structure. Its cradle charges the battery, so the scanner is always ready at the workstation.

The key is not the scanner's housing but the scan engine and decoding software: 2D imagers with advanced image processing decode worn, wrinkled, dirty or poorly printed codes at a high first-pass rate, while simpler models require repeated attempts. It is worth knowing that damaged codes often stem from printing or label selection issues, so using the right supplies can improve the situation as much as changing the scanner.
