MIFARE DUOX Smart Card

Union Smart manufactures the next-generation NXP MIFARE DUOX smart cards for forward-thinking enterprises, EV charging networks, and system integrators. As an IATF 16949 certified factory, we guarantee automotive-grade quality for your physical access and e-mobility solutions. Featuring cutting-edge ECC-based asymmetric cryptography, the MIFARE DUOX bridges the gap between traditional RFID cards and modern mobile device access (NFC and UWB). Benefit from our factory-direct wholesale pricing, OEM custom printing, and bulk chip encoding with an MOQ starting at 1,000 pcs.

MIFARE DUOX — Advanced ECC Smart Cards for EV Charging & Access Control

The MIFARE DUOX chip introduces asymmetric cryptography (ECC/PKI) to the contactless smart card market. Unlike traditional symmetric encryption (like AES-128 used in DESFire), ECC allows for highly secure, scalable, and interoperable offline authentication. This makes the MIFARE DUOX the ultimate choice for large-scale EV charging RFID cards and complex multi-site corporate access control systems.

Next-Gen Technology & Compatibility

• EV Charging Authentication: Features a ready-made credential structure specifically designed for Electric Vehicle (EV) charging networks, ensuring secure Plug & Charge user authentication.
• Aliro (CSA) Support: Built for the Connectivity Standards Alliance (CSA) Aliro standard, allowing seamless interoperability between physical MIFARE DUOX cards and mobile device access credentials.
• FiRa Consortium & UWB: Supports FiRa PKI/ECC mutual authentication, enabling high-precision Ultra-Wideband (UWB) applications for hands-free, highly secure door and vehicle access.
• Multi-Site Corporate Access: Eliminates the need to share symmetric master keys across different branch locations, significantly reducing the risk of global system compromise.

Frequently Asked Questions (FAQ)

Q1. What is MIFARE DUOX and what makes it different from MIFARE DESFire?

While MIFARE DESFire uses symmetric cryptography (AES-128), MIFARE DUOX uses asymmetric cryptography (ECC - Elliptic Curve Cryptography). With symmetric keys, the same secret key must exist in both the card and the reader, creating a vulnerability if a reader is hacked. With ECC, the reader only needs a public key to verify the card, making multi-site corporate access and global EV charging networks infinitely more secure.

Q2. What is Aliro and why is it important for access control?

Aliro is a new open standard developed by the Connectivity Standards Alliance (CSA). It aims to standardize digital access credentials so that physical smart cards (like MIFARE DUOX), smartphones (Apple Wallet/Google Wallet), and wearables can all seamlessly interact with the same door locks and access control readers.

Q3. Why is MIFARE DUOX the best choice for EV Charging RFID Cards?

EV charging stations are often decentralized and offline. Because MIFARE DUOX uses PKI/ECC authentication, charging networks can authenticate users without needing a continuous live connection to a central database. Additionally, our IATF 16949 certification ensures our cards meet the strict quality standards required by automotive and EV infrastructure companies.

Q4. Can you print our corporate logo and add QR codes for the EV charging app?

Yes. As a factory-direct OEM, we offer full-color CMYK offset printing on both sides. We can easily print your brand artwork along with a variable QR code that links directly to your EV charging mobile app or corporate portal.

Q5. Do you offer wholesale pricing for EV charging networks?

Absolutely. We specialize in B2B mass production. While our MOQ starts at 1,000 pieces, our pricing scales significantly for large-volume rollouts for Charge Point Operators (CPOs) and eMobility Service Providers (EMSPs).
