ST® Series Cards

OEM RFID Card Manufacturing for Access Control, Transit, Membership, and Closed-Loop Systems

Product Description

ST25T（ST25TA / ST25TB）Series cards are 13.56 MHz contactless smart cards designed for NFC applications that need reliable smartphone interaction and scalable deployment in established RFID infrastructures. ST25TA is an NFC Forum Type 4 tag based on the ISO14443-A interface, with NDEF support plus advanced authentication and digitization capabilities; it is well suited for brand protection, asset tracking, wireless pairing, smart posters, and virtual business cards. ST25TB is ISO14443-compatible and is commonly used for public transport and event ticketing.

For distributors, system integrators, solution providers, and brand owners, the main challenge is not just sourcing cards, but sourcing cards that perform consistently at scale, match existing reader environments, and can be customized for different customer projects. Our OEM manufacturing service solves that problem by delivering stable batch production, customized printing and encoding, and supply-chain-friendly documentation for international procurement.

Whether you need blank cards for resale, branded cards for a customer deployment, or pre-encoded cards for a managed rollout, we provide a manufacturing process designed for repeat orders, traceability, and integration into your B2B supply chain.

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.
