Abstract
A computer-implemented technique can receive, at a computing device, a uniform resource locator (URL) for a web page and a plurality of images. A number of pixels corresponding to a desired resolution for encoding the images determined and the images are converted to modified images having the desired resolution. The technique can then generate an animated two-dimensional barcode using a plurality of two-dimensional barcodes generated for the plurality of images, respectively. A specific two-dimensional barcode can be generated by: generating first data representative of the modified image and appending the first data to either an end of the URL to obtain a first modified URL or after a terminator bit of the two-dimensional barcode. The two-dimensional barcode can then be generated using the first and second data and third data representative of an error correction code (ECC) and that is based on the first data and the second data.
