Why are QR Codes with capital letters smaller than QR codes with lower case?

Left is upper-case HTTPS://EDENT.TEL/ and right is lower-case https://edent.tel/ You can clearly see that the one on the left is a "smaller" QR as it has fewer bits of data in it. Both go to the same URl, the only…

I have never had the chance to look under the hood either, but one week-end I have decided to to write a translator from the esoteric programming language wend (short for week-end), which I…

Relaxed Radix Balanced…
