Apparently, BMW dreams of a world where cold hard cash is no longer, and their keys are the currency of choice.  Afterall, BMWs have long been the choice of those trying to obtain social currency.  What the hell am I talking about?  BMW is set to introduce a car key which includes a contactless payment system.  The whole idea sounds a bit luni and will require a major paradigm shift in how we purchase products.  But when you look at Korea’s use of NFC in cell phones, it’s not that far off.  I suppose it could be ideal  when passing through a toll, although BMW’s drive and ride (a train) is a bit of stretch.

BMW plans to show of the tech at this year’s CARTES & IDentification show in Paris from 4th to 6th November 2008.
