Dual Interface Cards for OEM & Bulk Supply

Custom dual interface cards for secure identity, contactless transactions, and smart credential applications

Product Description

Dual interface cards are designed for applications that require both contactless and contact-based functionality in a single card. As an integrated B2B manufacturer, we support system integrators, solution providers, distributors, and wholesalers with flexible OEM production tailored to their project needs.

We help transform technical requirements into deployment-ready cards, supporting everything from chip selection and card personalization to large-volume production. With stable manufacturing processes and dependable supply, we help our partners deliver projects faster, simplify sourcing, and scale with confidence.

Designed for payment programs, secure access, e-government, healthcare, transit, and multi-application identity systems, our dual interface cards provide a practical and scalable solution for secure and versatile credential deployment.

Why Partner With Us

1. Direct-to-Factory Pricing
Work directly with the production source to avoid trading-company markups and unnecessary intermediary costs. This helps keep procurement efficient, cost-controlled, and transparent throughout the project.

2. Fast Prototyping & Market-Ready Response
We support rapid sampling and revision cycles, helping overseas engineers and procurement teams validate requirements and move projects forward without unnecessary delays.

3. In-House Control & Strict QA for Batch Consistency
From raw material selection to finished card inspection, every stage is managed under one integrated production system. Automated inspection and read/write testing help ensure stable performance and consistent quality across repeated orders.

4. High-Volume Capacity & Flexible Scalability
With monthly output of up to 12 million units, we can support large-scale rollouts while still accommodating small pilot runs and phased project launches.

5. Supply-Chain Stability
Based in mainland China, we benefit from a mature and deeply integrated manufacturing ecosystem with broad access to raw materials, components, finishing options, and supporting suppliers. This helps improve supply continuity, reduce sourcing risk, and support more stable long-term production.

Product Testing and Batch Control

Product Testing

We use a multi-stage inspection process to support stable output and reduce batch variation:

• Pre-production sample verification
• In-process inspection during manufacturing
• Final inspection before shipment
• Encoding verification for personalized cards
• Random sampling for batch consistency checks
• Appearance, print alignment, and readability checks

FAQ

Do you offer samples for testing?

Yes. We support sample requests for product evaluation, compatibility testing, and reader verification. Free samples may be available for qualified projects, depending on the card type, quantity, and cooperation scope.

What is your minimum order quantity (MOQ) and lead time?

MOQ and lead time depend on the card model, material, printing requirements, security level, and whether encoding is needed. Blank cards are usually faster to deliver than printed or personalized cards. For urgent projects, we can evaluate the fastest available production option.

Is the card compatible with existing access control systems?

Compatibility depends on the reader, controller, firmware version, security configuration, and backend system. For example, MIFARE Plus cards are often used for migration from MIFARE Classic environments, but final compatibility should always be confirmed by sample testing before mass deployment.

Do you provide product testing and batch traceability?

Yes. We can provide production testing, encoding verification, and batch traceability records. If required, we can also share inspection reports or a test summary for internal approval and project documentation.

How do you handle quality issues?

If a quality issue is reported, we will review the batch record, check the production and inspection data, and identify the root cause. Depending on the case and the agreed terms, we can support replacement, rework, or corrective action.
