Re: Even QR codes are dangerous.

Ages ago I was tempted to put replacement QR codes at all the labels in Tesco veggie section. I noticed recently they are gone.

You mean especially QR codes are dangerous?

I managed to find an app that reads them (and other barcodes) and only decodes & displays, with an option to save it or create a Firefox tab. Most phones seem to open the browser directly.

I despise people using obfuscated short codes (invented for Twitter and no longer needed there?). 1: The short code provider knows your IP, the time, your browser, OS and previous web site. 2: You have no idea what it will load.
