Near Field Communication (NFC) was initially promoted as a mobile payments method, but the technology has since been applied to a broader range of applications - and the list is still growing. One of these is a new system allowing for NFC implementation in a car key, which has been launched by the Dutch company NXP Semiconductors. The system is a production-ready single-chip solution dubbed KEyLink Lite (codenamed NCF2970) that enables a connection between a "smart" car key and external NFC-compliant devices, such as mobile phones, tablets and laptops.
NFC is a short-range (up to 20 cm/8 inches) standard of radio communication between electronic devices, so far mainly used in smartphones (such as the Nokia C7 and Google Nexus S). Combining NXP's existing car key security technologies, cryptography technology, and an NFC system operating at 13.56MHz frequency, KEyLink Lite will allow users to access sensitive car data by simply waving the key near an NFC-enabled device.
Some of the KEyLink Lite features would include:
NXP developed a multi-functional Smart Key prototype with BMW in the past, which was supposed to work as a method for mobile payments. The Dutch company, however, does not mention such an application for the current device.
The KEyLink Lite technology is now available for production. There is no word yet on which car manufacturer may actually use it, or when.
