Back in 2016, it became possible for the first time ever to open your car using your smartphone. Anyone lucky enough to own the new Mercedes E-Class (W213) simply had to hold their smartphone in front of the door handle to unlock the door. This whole new way to open a car was possible thanks to near-field communication (NFC) Huf had integrated as the first automotive supplier worldwide into door handles. As the name suggests, radio communication takes place between your smartphone and the door handle over a short distance of up to five centimeters. Simply put, NFC technology works like a transformer. When an electric current flows through the primary coil, this generates a magnetic field that is used for energy and data transmission in the frequency band of 13.56 MHz.

When it comes to deploying NFC technology in the automotive industry, the challenge is to produce a constant and powerful magnetic field with as little energy consumption as possible in order to ensure good performance. Huf has spent more than a decade researching NFC and has developed a range of patented solutions that ensure high-quality and extremely reliable communication with simultaneously low energy consumption.
The orders Huf is receiving for NFC door handles demonstrate just how happy customers are with the performance. In 2016, only a few smartphones were equipped with NFC capability, and digitalization was not as advanced as it is now. But nowadays, NFC is everywhere. Electric cars, for example, seek to offer whole new user experiences and so come as standard with NFC. The new BMW iX is the most recent example of a vehicle featuring NFC door handles from Huf as standard.
