BMW Group Research and Technology has developed a prototype for a multifunctional car key which enables cashless payment and personalised vehicle access. “As part of our research project we first integrated a security chip into the key casing, which communicates across short distances by radio with a card reader,” says Hans-Jörg Vögel, project manager at BMW Group Forschung und Technik.
In future the key could also be used for other transport systems. Indeed, electronic tickets for bus, train and air travel could all be stored on the chip. The credit card function in the security chip allows electronic payments to be carried out quickly, securely and conveniently from the prototype key.
