Automotive NFC Key Drivers 13
A NFC Keycard with cryptography costs <<1$
A Keyfob replacement costs 120~800$
=> considerable cost reduction also for initial
production costs on both car & key side.

Benefits in Automotive
• No external Booster required for required performance
• ST25R3914/15 offers by far the highest output power of all readers on the market. No additional
booster circuitry is required. This is critical with small antennas and metal environment
• Programmable Low power wakeup
• Optimized for operation in battery mode
• Automatic antenna tuning
• Reader is independent on placement. Influence of multiple objects (tags or others) is minimized
• Higher efficiency / less power consumption
• Fastest time to market (Dynamic Power adjustment, Automatic Gain Control, Squelch Feature)
• ST25R3914/15 reduced time to market at our customers significantly vs. competitor solutions
