Questions tagged [zxing]

ZXing (pronounced "zebra crossing") is an open-source, multi-format 1D/2D barcode image processing library implemented in Java, with ports to other languages. Its focus is on using the built-in camera on mobile phones to scan and decode barcodes on the device, without communicating with a server, though the library also supports use on a server.

Questions with this tag concern the open-source barcode encoding and decoding library ZXing.
