From BBC News | Technology | World Edition:
London commuters are getting the chance to swap the cash in their pocket for a digital wallet.
500 travellers have been issued with Nokia phones which swap digital cash via the technology used for the capital's Oyster travel card.

Swiping the phone against special posters will give participants access to information or local maps.
The trial uses the same Near Field Communications system behind the Oyster card.
