Near Field Communication (NFC) enabled cards or smartphones provide a convenient and secure way to access vehicles. Car keys have long been a weak link in vehicle security and will progressively be replaced by this technology as it filters down from premium vehicles to the mainstream. The NFC based solutions will not only add a more flexible and cost effective access mechanism, they will also provide new possibilities such as enabling rental car companies to send to a renters’ smartphone the ability to unlock and start their rental car using NFC.

ST’s NFC transceivers and SPC58 microcontrollers with embedded Hardware Security Modules (HSM), cover the most important requirements for such access control applications: security, reliability, usability and cost efficiency.
