Transport for London's (TfL) new contract for the Oyster card came into effect today, with Cubic Transportation Systems taking over from the TranSys Consortium.
TfL says the contract will save £30m and one of its priorities will be to investigate the potential for Oyster to be extended to new and existing technologies.
TfL's new ownership of the brand gives it the freedom to look into testing different types of IT, but a spokesperson said the company isn't ready to give examples of the possible extensions yet.
It says the new contract will save a total of £30m, as part of TfL's £5bn efficiency programme.
The Oyster card system was created in 1998 via a public finance initiative (PFI) contract with the Transys consortium, whose members included Cubic and HP.
TfL broke the contract in August 2008, and the break is effective from this week.
Shashi Verma, TfL's director of fares and ticketing, said: "TfL and Cubic will now work together to continue the success of Oyster, including investigating the future potential for Oyster to be extended to new and existing technologies and the commercial opportunities that provides.
"TfL has already undertaken a trial of Oyster on bank cards and mobile phones but now that we have complete control over the Oyster brand we can investigate options that make life easier and more convenient for Londoners to travel while also increasing the accessibility of Oyster."
