The Evolution of Vehicle Access


The NFC Car Key Card utilizes Near Field Communication to establish a secure, encrypted link with the vehicle. Unlike traditional keys, it requires no battery and fits in your wallet. Simply tap the card on the door handle or B-pillar to unlock, and place it on the console to start the engine—redefining user convenience.

Feature Highlights

"Tap-to-Unlock" Simplicity

No manual operation or wake-up required. Just tap the card on the sensor area for a second-level response. The passive design means it works perfectly without a battery, eliminating “dead key” anxiety and maintenance costs.

Chip-Level Security

Security is paramount. Built with a dedicated SE Chip utilizing International and National algorithms. It employs Mutual Authentication to verify digital signatures, effectively blocking relay attacks, signal interception, and violent disassembly.

Universal Compatibility

Seamless interoperability. Our digital keys fully support CCC (Car Connectivity Consortium) and ICCE standards. This ensures cross-brand compatibility and future-proof integration with the global digital car key ecosystem.

Customer

Premium Customization

From standard durability to luxury aesthetics. We offer a wide range of materials and surface treatments to match your vehicle’s brand identity and create a unique, premium key for their users.

Easy Sharing & Valet Access
