Zxing is an open source multi-format 1d/2d barcode image Processing Library, implemented in Java. The point is to use the built-in camera on the phone to scan and decode the barcode on the device without communicating with the server. However, the project can also be used to encode and decode barcodes on desktops and servers. These formats are currently supported: Upc-a and UPC-E EAN-8 and EAN-13
