| In terms of speed, a lot is going to depend on the specific processes they use on the door. I use, for example, electronic tickets stored on my phone on the train, and getting access to the platform simply means scanning a barcode on my phone screen at the gate. It's actually faster than having a human being check a paper ticket. On buses and trains in London, you can pay using contactless cards, and you simply touch the card on a pad on the gate as you enter - the same as you would with an Oyster card - and then (on trains) touch out at your destination station. Again, no slower than paper tickets. They're more than three months from beginning performances, so I've no idea how they're going to work it (and I'm not seeing it myself until January), but it needn't be too much slower - particularly since theatres in the West End at the moment tend to be doing bag searches on the door as you go in anyway, which already slows people down. |
