Someone somewhere at DB has written a QR code generator that outputs QR codes as HTML tables. I'm not sure if I should be impressed or horrified.
About the only potential complaint is that screen readers would take forever and a day to "read" the table out loud

@csolisr Hmm, i have no access to a screenreader, but i'd assume, that some meta-data in the table should make it clear it's encoded data and not readable text.

But a good point.

Then again, if a blind user requires verifying that the QR code was correctly generated pixel per pixel, a table would make navigating through each dot much more easily than a vectorial image. Edge case scenario, but hey!
