Part of my commute involves cycling to and from Cambridge North station. It's now the time of year where I need to use my bike lights. What normally happens is that I lock my bike at Cambridge North, go through the ticket barriers using my paper season ticket, realise that I have left my bike lights on my bike, exit the ticket barriers using my season ticket, collect bike lights, then attempt to enter the barriers again. The barriers won't allow me to re-enter, and I have to get a member of staff to let me through. The last time this happened, the staff at the gateline wrote "09" on my season ticket (I guess he thought that my season ticket stopped working altogether).
If I used a smart card (or used an Oyster card at a London station), would it also prevent re-entry? With a paper ticket, I can prove I have a valid ticket for travel and get waved through, but would I have difficulty getting staff at the gateline to let me through with a smart card that won't open the barriers?
