So, uhm. If someone doesn't have a (credit/debit) card to pay with, they just need to bring a (smart) card with them so they can pay with cash?
Why not? It is simply an electronic replacement for a paper based Promise to Pay. It would save money and the environment in the future, and the card doesn't just have to be for P2Ps, it could carry a cash amount loadable at ticket offices / Pay Points or even via NFC capable smartphones (as with some bus operators), and tickets bought online.
