Contact-less cards, embedded in mobile phones so that you can swipe them instead of your pre-paid card. Pre-payment is good because it makes public transport easier to pay for and moves payment queues along a bit quicker. Can also help the operation of the transport operator by minimising cash handling, so an all round good thing really.

And we know that pre-payment cards can be used for other nice things (like Chromaroma) as well as not-so-nice-things, which could help to make public transport more attractive vs private cars.
