Ok, we didn't see this one coming. Then again, our idea of a Sunday drive is taking a taxi uptown. So imagine our surprise to find that the people at NXP Semiconductor and BMW thought it was a good idea to integrate a car key with a contact-less payment system. The prototype key features NXP's SmartMX security chip -- the same chip at the heart of many of the world's e-passports -- making it possible to use the key to pay for fuel at the pump, tolls (after uh, switching off the engine in the toll lane), or at any number of places where flagrantly flaunting your BMW logo-adorned key could get you noticed. What piqued out interest, however, is the promise that such a key could hold your personal access rights to unlock, and then start the engine of your own car or that of a rental company's while automatically configuring the interior with all your custom in-vehicle settings such as radio presets, mirror and seat adjustments, etc. It would even authorize (and pay for) future on-line BMW services across the entire fleet of Bimmers you don't own, but might choose to outfit the family with if the smart key option was available. The prototype on display at the CARTES & IDentification show in Paris next week will likely closely resemble the image above... only without the transformer.

Considering just how well the first round of RFID ePassports withstood subversion attempts from hackers, we're amazed that anything needs to be tweaked at all. Sarcasm aside, NXP is all set to make Germany the first country on the planet to utilize second-generation ePassports, as the EU-set deadline to migrate doesn't pass until June of 2009. The new passports will include a SmartMX chip that allows biometric data to be "securely stored on the passport," and the 80kb of onboard storage also holds the individual's photo, name, and date / country of birth. Of note, NXP even goes so far as to gloat about the chip's ability to "guard against attack scenarios," but we'll be interested to see how long it takes the oh-so-motivated hacking community to find a backdoor when these launch later this month.
