Sorry mate but that is utter tosh. It might be set up to read a radio transmission but unless I insert my phone in the slot I don't get in. Even then it is two or three tries. That said, I am not complaining, just correcting.When you get to the turnstile do you put your phone in the slot like a seasoncard? Everyone seems to do that but you are supposed to hold your phone a cm from the reader because it works by radio transmission. Using the phone as a bar code is not very reliable. You can have problems with screen brightness for example.
