Re: So Download Festival are trying to go bankrupt?
When considering a new system that involves money, think not how it would work, but how it could go wrong.
This system is an absolute dream come true for the small-time fraudster and grifter. All they need is a small RFID sniffer, an RFID programmer and a supply of RFID tags that look a bit like the ones the organisers have.
Once in the festival, the grifter gets his RFID sniffer going then goes looking for people who look a bit richer than normal festival goers; designer clothing and so on, and walks past them. His RFID sniffer grabs the codes, which in the privacy of his tent he puts onto some more RFID tags, which he sells to willing stooges to try out. When he finds one that is loaded with cash and is an access-most-areas tag, he duplicates lots of them and sells 'em for lots of cash (cash will of course still be present, so people can buy drugs).
Pretty soon the guy who had his tag sniffed finds he ain't rich any more and the festival organisers want to have a quiet word with him, along with all of his clones...
This is how this system will break, mark my words.
