Oyster-card users can currently access information and top up their card online through the TfL website, but there is speculation that TfL is to enable Oyster customers to pay for items such as newspapers with their cards.
The government body has already discussed the brief and future online development of the brand with several digital shops.
The Oyster card was launched in London in 2001. According to the latest TfL figures, published in January this year, there are about 5m Oyster-card users - a growth of 1.9m since December 2005 that has been fuelled by price rises for non-users.
Oyster cards are valid on Tube, DLR, tram and national rail networks within selected zones, and across all of London's bus network.
