Product Overview
The DO RFID Reader NFC Card with ST25TN01K chip delivers a reliable, standards-compliant NFC solution engineered for commercial identification, access management, and authentication applications. Housed in a white PVC CR80 card format, this product combines the ST25TN01K chip’s unique digital signature technology with the proven interoperability of NFC Forum Type 2 and ISO/IEC 14443 Type A protocols. System integrators, access control contractors, loyalty program operators, and industrial asset tracking teams choose this card when they need tamper-evident authentication, consistent read performance, and long-term data retention across large-scale deployments.
For wholesale buyers and project managers, the real value lies in the chip’s TruST25 digital signature — a factory-locked cryptographic mechanism that enables instant verification of card authenticity at the point of use. This directly addresses counterfeiting risks in membership systems, secure entry, and supply chain verification workflows. When sourcing from the do rfid reader manufacturer, procurement teams gain access to stable production capacity, batch-to-batch consistency, and technical support for integration into existing reader infrastructures.

Industrial Applications
System integrators and project contractors deploy this NFC card across multiple commercial and industrial scenarios:
- Access Control & Secure Entry: Used in office buildings, co-working spaces, and restricted industrial zones where unique card authentication prevents unauthorized entry. The TruST25 signature allows instant verification without cloud dependency.
- Loyalty & Membership Programs: Retail chains and hospitality groups issue these cards for customer loyalty tracking. The 208-byte memory stores member identifiers and point balances, while the anti-counterfeit feature protects program integrity.
- Asset Identification & Tool Tracking: Maintenance teams and warehouse operators attach or issue cards to equipment, tools, and reusable containers. The robust write endurance supports frequent check-in/check-out updates over years of use.
- Visitor Management: Temporary badges for guests, contractors, and delivery personnel benefit from the card’s compatibility with existing NFC reader infrastructure and the ability to pre-configure expiry data in memory.
- Supply Chain Authentication: Logistics companies and brand owners use the digital signature to verify the authenticity of returned goods or high-value items moving through reverse logistics channels.
OEM / ODM Manufacturing Support
The do rfid reader manufacturer supports OEM and ODM customization programs for clients who require branded cards, pre-encoded memory, or custom graphic printing on the PVC surface. Procurement teams can specify:
- Custom artwork, logo printing, and serial numbering on card face
- Pre-programmed UID or memory content for plug-and-play deployment
- Packaging configuration: bulk packs, individual sleeves, or retail-ready clamshells
- Encoding of the TruST25 digital signature verification workflow for proprietary reader systems
- Custom data structure mapping for integration with legacy access control or asset management databases
OEM partners benefit from consistent production quality across batch runs, documented chip programming protocols, and direct technical liaison for compatibility testing with their reader hardware.
Factory Production Advantages
As a specialized RFID and NFC card manufacturer, the factory operates dedicated production lines for ISO-standard card manufacturing. Key capabilities that matter to wholesale and project buyers include:
- Stable Production Capacity: Multiple automated card lamination and chip embedding lines support order volumes ranging from small pilot runs to large-scale project deployments of 50,000+ units per month.
- Batch Consistency: Inline chip programming verification and visual inspection ensure that each card meets the same electrical and dimensional tolerances, reducing field failures during large rollouts.
- Fast Lead Times: Standard bulk orders ship within 5 to 10 working days. Custom-printed or pre-encoded cards are accommodated with agreed timelines based on complexity and volume.

Frequently Asked Questions
What is the read distance of the ST25TN01K NFC card?
The typical read distance is up to 10 cm, depending on the reader antenna design, power output, and environmental interference. In controlled access readers with optimized antennas, reliable reads at 5–8 cm are common.
Can the card be used on metal surfaces?
No. This card is not designed for on-metal mounting. For metal surface applications, a ferrite-backed or on-metal NFC tag should be selected instead.
How does the TruST25 digital signature protect against counterfeiting?
The ST25TN01K chip contains a factory-locked digital signature that any NFC reader can validate using public-key cryptography. If the signature does not match, the card is identified as non-genuine, preventing cloned or unauthorized cards from being accepted in your system.
What memory is available for user data?
208 bytes of usable memory are available for storing application data such as user IDs, expiry dates, access permissions, or loyalty point values. This is separate from the UID and system configuration areas.
Can I get custom printing or encoding on bulk orders?
Yes. OEM and ODM customization is supported for orders of 500 pieces or more. Contact the do rfid reader manufacturer with your artwork files or data encoding requirements for a project-specific quotation.
What is the minimum order quantity?
The minimum purchase order quantity for this product is 10 cards. Volume discounts apply from 20 pieces upward.
Is the card compatible with standard NFC smartphones?
Yes. The card is NFC Forum Type 2 compliant, which means it can be read and written by any NFC-enabled smartphone running Android or iOS with appropriate app support for Type 2 tags.
How long does a bulk order take to ship?
Standard stock orders ship within 5–10 working days. Custom-printed or pre-encoded orders require additional production time, which will be confirmed at the time of order placement.
Do you provide technical support for integration?
Yes. Technical documentation and application support are available to assist system integrators and project teams with reader-side development, memory mapping, and authentication workflow implementation.
Can I request a sample before placing a bulk order?
Samples are available for qualification testing. Contact the do rfid reader manufacturer with your project details to arrange sample shipment and discuss volume pricing.
