Next generation iPhone 5 and several new Android phones will include a new technology that will change how our daily behaviors and how we use our smartphones. But while we are anxiously waiting for these new devices, BMW is already giving us a preview of this technology. NFC, short for Near Field Communications, is a short-range high frequency wireless communication technology which enables the exchange of data between devices over about a 10 centimeters (3.9 in) distance.

Currently NFC is already in use for public transportation and payment, but it is is primarily aimed at usage in mobile phones.

For the next generation ConnectedDrive, BMW is working on a massive expansion of the functions for car keys. For example, with the help of a transponder that has a range of a few centimeters, trigger sensors will open doors or gates, replacing some of the existing devices.
