The General Barcode.
High Density – This QR Code can contain up to 1852 characters
(a total of 1,264 characters of ordinary/ASCII text ).

13. ZXING is an open-source, multi-format 1D/2D barcode image processing library
implemented in Java, with ports to other languages.
However the project can be used to encode and decode barcodes.
