As electric vehicles, connected cars, and smart mobility continue to expand, secure contactless identification has become increasingly important. Automotive manufacturers, EV charging operators, mobility companies, and system integrators are looking for NFC technologies that can provide both strong security and convenient user interaction. At XINYE RFID, a professional RFID smart card manufacturer, we now offer cards built on NXP’s latest MIFARE DUOX chip — purpose-designed for car key cards and EV charging cards.
Why Use MIFARE DUOX® for NFC Car Key Cards?
NFC car key cards are becoming an important part of modern vehicle access systems, especially in the electric vehicle and smart mobility markets. Instead of relying exclusively on traditional mechanical keys or key fobs, an NFC car key card can provide a convenient physical credential for vehicle authentication.
A typical NFC car key card allows an authorized user to interact with an NFC-enabled vehicle reader. Depending on the vehicle system architecture, the card can be used as a secure credential for vehicle entry or other authorized functions.
However, automotive applications require significantly higher security than ordinary identification cards. A car key credential represents access to a valuable physical asset, so protection against unauthorized access, credential duplication, and other security threats is essential.
MIFARE DUOX® is designed specifically for high-security applications and combines asymmetric and symmetric cryptography to support secure authentication architectures. Its certificate management capabilities can also help support scalable credential management in large automotive ecosystems.
This makes MIFARE DUOX®chip an attractive option for NFC car key cards used by electric vehicle manufacturers, automotive technology companies, fleet operators, vehicle-sharing services, and smart mobility providers.
Guangdong Xinye Intelligent Label Co., Ltd. can manufacture customized NFC car key cards according to customer project requirements. Card appearance, printing, branding, dimensions, materials, surface finishes, and other manufacturing specifications can be customized for different automotive applications.
MIFARE DUOX® EV Charging Cards
The rapid growth of electric vehicles is also driving demand for secure EV charging authentication. Public charging networks, private charging stations, workplace charging facilities, and fleet charging systems all need reliable methods to identify users and authorize charging sessions.
An NFC EV charging card provides a simple contactless authentication method. The user presents the card to an NFC-enabled charging station, and the charging system can identify the associated credential and authorize the charging service according to the backend system configuration.
Security becomes increasingly important as EV charging networks grow. A charging card may be connected to an individual account, company account, fleet, vehicle, or payment-related service. Unauthorized use or compromised credentials can therefore create financial and operational risks.
MIFARE DUOX® provides a high-security NFC technology for applications where strong authentication and secure credential management are required. Its combination of asymmetric and symmetric cryptography, together with certificate management capabilities, can support secure authentication architectures for EV charging ecosystems.
MIFARE DUOX® EV charging cards can therefore be considered for public EV charging networks, fleet charging systems, workplace charging, private charging infrastructure, and other smart mobility applications.
For EV charging operators and solution providers, the NFC card is only one part of the complete system. The final solution normally includes NFC readers, charging stations, backend software, user accounts, authentication services, and payment or billing systems. Xinye focuses on NFC card manufacturing and can supply the customized MIFARE DUOX® cards required by the customer’s system.
Guangdong Xinye Intelligent Label Co., Ltd. supports global customers with customized RFID NFC card manufacturing for automotive, EV charging, smart mobility, secure access, and other applications. By combining advanced RFID technology with professional card manufacturing and OEM/ODM customization, Xinye aims to provide reliable physical NFC credentials for the next generation of connected mobility.
