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.
@cato that’s honestly not the worst idea. Easily supports ancient devices that don’t do svg properly yet, is natively scalable, and probably even saves some data over anything except svg where you put the entire code into one big chonky path data.

@jaseg Now I'm wondering if SVG using would even be so much more than a single path after it gets zipped...

That aside though, are you sure a 2 colour bitmap wouldn't be smaller than an HTML table? It can't have that much overehead, right?

@darkwiiplayer especially older browsers commonly don’t support scaling images with nearest-neighbor interpolation, so they would render an image blurry.
