True, but the beauty of the OC to me is how disposable it is. So I can keep my debit card, my phone stashed away deep in a pocket whilst keeping the OC close to hand. They do make excellent back ups just in case I didn't top up the OC though!
Really? I'm sure I heard some Android phones supported NFC. Could be wrong. I don't live in America.
The Oyster card has surely had its day. I just got rid of it as soon as they launched contactless as its just an extra card in your wallet. Contactless has all the benefits of oyster and also the added convenience of not having to top it up or add travel cards all the time. People are just used to using it and will surely only be used by the minority and will gradually be phased out in time.... or maybe just used by tourists.
