Re: OPtion?
Given that the NHS app uses QR codes for both the travel and event passes I assumed that there'd be a corresponding reader or app that could validate them, thereby making fakes much more difficult. However, a quick Google around didn't reveal anything that can be used by pubs, clubs, etc., and there's nothing obvious in the Apple app store, so I don't really understand how this is going to work properly. The passes can be downloaded as pdf., for printing out by users without a smart phone, so once you've seen one it's trivial to mock up a fake.
Maybe the validation app/reader is a work in progress?
