MIFARE Duox Cards

CC EAL6+ Certified Security for Access, EV Charging, and Tomorrow's Connected Infrastructure

Product Description

MIFARE DUOX cards are 13.56 MHz contactless smart cards built on NXP's DUOX platform — combining asymmetric ECC and symmetric AES-256 cryptography on a single chip with CC EAL 6+ certification. Designed for high-security enterprise access, EV charging, and multi-site credentialing, DUOX replaces traditional shared-key architectures with a PKI-based model that eliminates secret key leakage risks from reader terminals.

For distributors, system integrators, solution providers, and brand owners, the main challenge is not just sourcing a high-security card — it's sourcing cards that perform consistently at scale, match existing reader infrastructures, and can be fully customized for different customer projects. With EAL 6+ deployments especially, procurement teams also face rising pressure around supply chain transparency: they need verifiable chip provenance to mitigate counterfeit risk, complete batch-level traceability to satisfy audit requirements, and documentation that meets international compliance standards before goods even clear customs.

Our OEM manufacturing service addresses that full procurement reality. We deliver fully customized MIFARE DUOX cards with certified asymmetric key injection, stable batch production, custom printing and encoding, and supply-chain-friendly documentation — including traceable production records and verified security parameter reports. Whether you need EAL 6+ cards for government facilities, PKI-enabled EV charging credentials, or multi-application enterprise badges, every shipment arrives with consistent quality, predictable supply, and the manufacturing transparency that large-scale security deployments demand.

Key Features

1. Direct-to-Factory Pricing
Work directly with the production source, bypassing trading companies and middleman markups. This keeps your procurement cost low and pricing fully transparent across every project stage.

2. Agile Prototyping & Global Market Alignment
We move fast, without bureaucratic delays. Quick sampling and revision cycles help overseas engineers and procurement teams test, validate, and deploy solutions at the speed of the market.

3.Full In‑House Control & Strict QA for Batch Consistency
From raw material to finished card, every stage runs under one closed‑loop system. 100% automated inspection and read/write testing ensure near‑zero defects and stable quality batch after batch — because consistency matters as much as cost in repeat orders.

4. High-Volume Capacity & Flexible Scalability
Powered by a proven capacity of 12 million units per month, we have the industrial muscle for massive global rollouts. Yet, our lines remain agile enough to seamlessly support your small initial trial batches.

5. Supply-chain-ready manufacturing
We go beyond basic casings. Our engineering team delivers deep technical customization, including complex data encoding (such as MIFARE® variants), precision antenna tuning, and ruggedized encapsulation for demanding, application-specific environments.

FAQ

Do you support samples and free samples?

Yes. We support sample requests for product evaluation and compatibility testing. Free samples may be available depending on the project, quantity, and cooperation scope.

What is your MOQ and lead time?

MOQ and lead time depend on the card type, customization level, printing requirements, and encoding needs. Blank cards can usually be delivered faster than fully customized printed and encoded cards.

Can you provide product testing and batch traceability?

Yes. We support production testing, encoding verification, and batch traceability records. If needed, we can provide a test summary or inspection record for your internal review.

How do you handle quality issues?

If a quality concern is reported, we review the batch details, inspect the production record, and identify the root cause. Depending on the case, we can support replacement, rework, or corrective action based on the agreed terms.

Is the product compatible with existing systems?

Compatibility depends on the selected reader environment. We strongly recommend sample testing before mass deployment to validate system integration.
