Tax Boy: QR codes are the stupidest idea ever.also, WTF QR Codes
heypete: Tax Boy: QR codes are the stupidest idea ever.also, WTF QR CodesWhy? They're perfectly reasonable ways of encoding data. I actually use some for error-correcting ways of writing data to offline paper backups: if one gets a little smudge or dirt, no big deal. Much less error prone than OCR or manually typing stuff. I can shrink them down pretty small, put a ton on a single page, and read them with a reasonably high-resolution scanner.Typing on mobile devices can be a pain, so using them to present links to mobile users is pretty handy.One particular advantage: exchanging the shared secret for TOTP-based one time passwords (such as with Google Authenticator). Manually entering the shared secret is slow and error-prone. QR codes reduce this to "point and click".
Cormee: QR codes as replacements for URLs are the very definition of stupidity. They're a solution to a problem that doesn't exist.
