Its library has multiple components and we will be using the ‘core’ for QR code creation in our Java example. ZXing ('Zebra Crossing') is the popular API for QR code processing in Java. If you have a smartphone with iOS or Android then you can install a QR Code app easily in a minute and scan all those codes to read the information. It may contain product information, price detail, web url, etc. You can see advertisements in newspapers having QR codes. This became easily popular because of the advent of mobile apps that can be used as a QR code scanner to read the information in QR codes. Any place where the barcodes are being used can be replace by QR codes.Ĭan you scan and comment on what is in this picture? Also, the barcodes can be output to PNG, GIF, JPEG, and SVG. QRGen Barbecueis an open-source Java library that supports an extensive set of 1D barcode formats. So why is it popular? QR code can store more volume of data in small area compared to the standard barcode formats. Were going to explore several libraries: 1. There are extensions to these standard types available, using which custom data also can be coded. The four standard modes of data for creating QR code is numeric, alphanumeric, byte / binary and Kanji. Quick Response Code (QR Code) is a two-dimensional matrix like barcode, designed by a subsidiary of Toyota to mark their vehicles for tracking in their manufacturing facilities.
