Well, I suppose you could describe it like that. From my perspective, Oyster is just enabling you to avoid the obscene gouging that you'll be subjected to if you buy a paper ticket. And, in fact, it's the ONLY currency that you can use on a London bus now. (Cash fares for buses have been eliminated).
