# MatchBench

> Free barcode comparison in your browser. Scan a reference and each label, see an exact match or the first difference, and download the results.

Compare barcode values with a phone or tablet camera, a keyboard barcode scanner or typed entry. Set a reference, then check one label or a run of labels against it and see Exact match or Different value, with the position of the first character that differs. Every comparison stays in a list with its reference, entry source and time. Download the comparisons as CSV, an A4 PDF report or a portable project backup, keep your work on this device if you choose, and prepare the tool for offline use.
