Product Overview

The MIFARE DESFire EV3 8K chip embedded in a standard white NFC PVC card delivers a secure, high-performance contactless smart card solution purpose-built for multi-application deployments in access control, transit ticketing, micro-payment, and identity management. System integrators, project contractors, and commercial end users choose this card when they require strong data security, reliable read performance across NFC-enabled devices, and stable long-term supply from a manufacturer that supports bulk procurement and OEM customization.

This card operates at 13.56 MHz with a read distance up to 10 cm and supports data transfer rates of 106, 212, 424, and 848 kbit/s, ensuring compatibility with existing reader infrastructure and NFC smartphones. The 8 kBytes of onboard memory allows multiple applications to reside on a single card without performance degradation, making it a practical choice for smart city programs, university ID systems, hospitality key cards, and event access control.

Product Advantages

Procurement teams and technical buyers select this card because it solves specific operational challenges: the need for one card that handles secure door access, cashless vending, time tracking, and identity verification without issuing separate credentials. The DESFire EV3 chip architecture supports up to 28 independent applications per card, which reduces card issuance costs and simplifies user management for large-scale deployments.

For distributors and wholesalers, the 8K memory variant offers a cost-effective balance between storage capacity and unit price, enabling competitive pricing for high-volume projects. The DO RFID Reader factory produces these cards with batch consistency verified across production runs, ensuring that integrators receive uniform card performance whether ordering 500 or 50,000 units. Stable production capacity and fast lead times support project schedules that cannot tolerate supply interruptions.

Frequently Asked Questions

Is this card compatible with existing access control systems that use older DESFire models?
Yes. The DESFire EV3 chip is backward compatible with DESFire EV1 and EV2 infrastructure when programmed with compatible encryption keys and application settings. System integrators should verify reader firmware support for EV3 command sets before full deployment.

Can the factory pre-encode data onto the cards before shipping?
Yes. As part of the OEM service, the factory can pre-personalize UID, application directories, and encryption keys per the customer’s specification. This reduces on-site programming time during large-scale deployments.

What is the typical lead time for a bulk order of 5000 cards with custom printing?
Standard lead time is 12-18 working days from artwork approval, depending on print complexity and encoding requirements. Production capacity allows for schedule compression when project deadlines require expedited delivery.

Does the card work with standard NFC smartphones for field testing?
Yes. The card is NFC Forum Type 4 compliant and can be read by iOS and Android devices using NFC Tools or custom applications, making it suitable for field verification and pilot testing before system-wide rollout.

What encryption should be used for a transit ticketing application?
AES128 is recommended for new deployments requiring strong data protection. The hardware cryptographic engine supports AES128 without performance impact at all four data transfer rates. For legacy systems, 3KTDEA is also supported.

Can I receive samples before placing a bulk order?
Yes. Sample cards can be shipped for compatibility testing with your readers and software. Contact the factory to arrange sample quantities and delivery terms.
