The QR code itself, at the physical level, is just an encoding of a bit stream, length given by the size (in b/w squares) of the code. Go up one (or two) levels, and first bits are a tag indicating the meaning, or semantics, of the rest of the bit stream. It doesn't have to be a URL, but that is what most people have seen it as.

If it really is a URL (which is quite likely) to a web service for the user to transfer money from his bank account to the parking service, replacing it with a URL to another web service for the user to transfer money from his bank account to someone else's bank account is not that difficult. As long as you need to establish some contractual agreement with the parking lot before parking there, you can in theory have a white list of money recipients, to prevent this kind of fraud - but it doesn't work in practice: There will be lots of parking lots where you do not have any prior agreement, so you have to accept the web service that comes up when you go to the QR supplied URL. There is no easy way for you to know whether it is real or fake.

In the metal days, you could be reasonably sure that the coins you dropped into the slot actually landed in the money box of the parking lot owner. Today you can't be that certain about the owner receiving the right bits. I sort of trust(ed) coins a lot more.

Straw Poll

Were you affected by the geomagnetic storms this past weekend?
Communication disruptions, electrified pipes, random unexplained blue-screens in Windows - the list of effects is terrifying.
