Guangdong Xinye Intelligent Label Co., Ltd., leveraging decades of expertise in smart card technology, proudly unveils a true game-changer: the revolutionary High-Temperature Resistant RFID/NFC Digital Key Card. Deeply understanding the unique thermal challenges inside modern vehicles, we developed this smart card specifically for new-energy vehicle key applications, permanently eliminating one of the industry’s most persistent pain points.
Built from aerospace-grade PVC/PET/PC composites with advanced heat-resistant additives and crafted through precision multi-layer hot-lamination, the card operates flawlessly from -40°C to +105°C and can withstand short-term spikes up to an impressive 150°C. Whether exposed to scorching summer dashboards, freezing winter starts, or the intense heat near electric motors, the chip remains stable, the signal stays strong, and the card never warps or fails.
What truly sets carmakers’ minds at ease is Xinye’s exclusive WPC load-state burn-protection technology, a breakthrough that finally ends the dreaded “wireless charging kills the key card” nightmare. When drivers place both their phone and key card on the center-console wireless charger (an everyday habit for millions), conventional cards are instantly destroyed by sudden power overload,the smart key card has malfunctioned and is thus unusable.. Under the exact same extreme conditions, Xinye’s card emerges completely unharmed: chip intact, data untouched, the chip position of the smart card will not bulge.
Every card carries a unique laser-etched serial number and supports premium customization options including gold/silver hot-stamping, laser coding, and inkjet serialization, delivering both stunning brand aesthetics and unbreakable one-vehicle-one-card traceability. Measuring the universal CR80 size of 85.6 × 54 mm and embedding automotive-grade high-frequency secure chips, it integrates seamlessly with leading OEM digital-key platforms and smartphone NFC ecosystems. Fully RoHS-compliant, waterproof, dustproof, bend-resistant, and built to last the lifetime of the vehicle, it is the definition of reliability.
As an IATF16949-certified automotive supplier already trusted by multiple top-tier domestic and international NEV manufacturers, Xinyetag proves with every shipment that when temperatures run wild, our smart cards stay perfectly calm. Choose the Xinye High-Temperature RFID/NFC Key Card and give the unbreakable peace of mind.
