In the, we learned how to generate QR Codes in java using google’s Zxing library. If you have not read my previous tutorial, I encourage you to have a look at that first before reading this one.In this post we’ll learn how to read QR code images and extract the data encoded inside the QR Code.Scan the above QR code using your smartphone. You’ll get my site’s url -. We’ll write a similar scanner in Java where you can pass a QR code image, and the program will return the data encoded in the QR code.
