Product Overview

The MIFARE DESFire EV1 4K 13.56MHz Blank RFID NFC Printable Card from DO RFID Reader is a high-security contactless smart card designed for commercial and industrial identification, access control, and payment systems. Built around the NXP MIFARE DESFire EV1 4K chip (MF3ICD41), this card delivers 4 kilobytes of memory, AES-128 encryption, and ISO/IEC 14443-A compliance. System integrators, project contractors, and distributors choose this card when they need a secure, programmable credential that supports multiple applications on a single platform. Whether deployed in large-scale access control networks, transit fare collection, or loyalty programs, the card provides the cryptographic protection and memory capacity required for real-world commercial deployment.

Key Features

• High-Security Encryption: AES-128 mutual authentication and data encryption protect against cloning and unauthorized access. Common Criteria EAL4+ certification provides independent validation for government and financial applications.
• 4K Memory Capacity: 4 Kilobytes of onboard memory supports multiple application files, data structures, and secure storage within a single card. Ideal for multi-application credentials such as access + payment + ID.
• NFC Forum Type 4 Protocol: Compatible with all NFC-enabled smartphones and readers. Enables mobile-based authentication, ticketing, and identity verification without dedicated reader hardware.
• Fast Data Transfer: Up to 848 kbps data transfer rate reduces transaction time for high-throughput environments such as turnstiles, fare gates, and point-of-sale terminals.
• Durable PVC Construction: Standard CR80 card size (85.6mm x 54mm x 0.8mm) made from waterproof, durable PVC. Withstands daily wear in industrial, outdoor, and high-traffic commercial settings.
• Printable Surface: Blank white surface compatible with dye-sublimation and thermal transfer printers from Zebra, Epson, and Canon. Supports custom branding, photo ID, barcodes, and serial numbers.
• 7-Byte UID: Factory-programmed unique identifier ensures each card is individually traceable for asset tracking and identity management.

Technical Specifications

Industrial Applications

The MIFARE DESFire EV1 4K card is deployed across multiple sectors where secure contactless identification is required.

• Access Control: Used by commercial buildings, data centers, hospitals, and government facilities for personnel entry. AES-128 encryption prevents credential cloning, a common vulnerability in older RFID systems.
• Transportation & Transit: Supports fare collection systems for buses, trains, and toll roads. Fast data transfer and multi-application support allow a single card to handle ticketing, stored value, and commuter passes.
• Payment Systems: Suitable for closed-loop payment environments such as campus cards, corporate canteens, vending machines, and event cashless payments.
• Loyalty Programs: Enables secure points accumulation, reward redemption, and member identification without exposing sensitive customer data.
• Identity Management: Used for employee badges, student IDs, and government-issued credentials where data integrity and tamper resistance are mandatory.
• Hotel & Hospitality: Door lock credentials for hotel rooms, resort access, and guest services. Printable surface allows property branding and room number printing.

OEM / ODM Manufacturing Support

DO RFID Reader operates as a dedicated RFID card manufacturer with in-house production lines for PVC card fabrication, chip encoding, and quality inspection. OEM and ODM customers receive fully customized cards with their own artwork, logo, serial numbering, barcode printing, and chip encoding. The factory supports custom UID ranges, pre-programmed application structures, and bespoke packaging for branded distribution programs. Technical documentation, sample approval, and production timeline coordination are provided for every custom order. Batch consistency is maintained across all production runs, ensuring that cards issued years apart remain electrically identical and compatible with the same reader infrastructure.

Bulk Supply & Project Deployment

Wholesale buyers, system integrators, and project contractors benefit from stable production capacity and fast lead times. The factory maintains buffer stock of blank cards and chips to support urgent deployment schedules. Bulk pricing is available from 200 pieces upward, with additional discounts for container-level orders. Each batch undergoes antenna tuning verification, memory read/write testing, and visual inspection before shipment. Cards are packed in sealed cartons with anti-static protection for long-distance export. Long-term supply agreements are supported for multi-year projects where consistent delivery and fixed pricing are required. Distributors receive marketing materials, sample support, and dedicated account management for their regional markets.

Why System Integrators and Distributors Choose This Card

For project-based deployments, card consistency across multiple batches is critical. DO RFID Reader produces cards with stable antenna impedance and chip response characteristics, reducing reader configuration time during installation. The 4K memory and DESFire EV1 architecture support complex data structures for multi-application credentials, eliminating the need to issue separate cards for access, payment, and ID. Compatibility with existing ISO/IEC 14443-A reader infrastructure means no additional hardware investment is required for upgrades from older MIFARE Classic or Ultralight systems. For distributors and wholesalers, the combination of competitive bulk pricing, reliable production capacity, and technical support reduces procurement risk and simplifies supply chain management.

Frequently Asked Questions

What is the difference between MIFARE DESFire EV1 and MIFARE Classic?
DESFire EV1 uses AES-128 encryption and Common Criteria EAL4+ certification, offering significantly higher security than MIFARE Classic. It also supports multiple independent applications on a single card, while Classic is limited to a single application.

Can this card be used with existing 13.56 MHz readers?
Yes. The card uses ISO/IEC 14443-A communication, which is the most widely adopted standard for 13.56 MHz RFID readers. Most commercial access control and payment terminals support this protocol.

Is the card compatible with smartphones for NFC reading?
Yes. The card supports NFC Forum Type 4 protocol, making it readable and writable by NFC-enabled Android and iOS devices with appropriate applications.

Can I print on the card surface?
Yes. The card has a blank white PVC surface suitable for dye-sublimation and thermal transfer printing. Standard card printers from Zebra, Epson, Canon, and similar brands can print text, images, barcodes, and serial numbers.

What is the minimum order quantity for wholesale pricing?
Wholesale pricing begins at 200 pieces per order. Larger quantities of 600 or 1000 pieces receive further discounted unit pricing. Contact DO RFID Reader for bulk order quotes above 1000 pieces.

Does the factory support custom chip encoding for OEM projects?
Yes. DO RFID Reader provides ODM encoding services including UID programming, application structure creation, and data file pre-loading. Custom encoding specifications are accommodated during production planning.

How long does production take for a standard bulk order?
Standard production for blank or pre-encoded cards typically completes within 7 to 15 working days depending on order volume and customization requirements. urgent orders can be expedited upon request.

Is the card resistant to water and physical wear?
Yes. The PVC construction provides water resistance and durability for daily handling in commercial environments. The card is suitable for indoor and sheltered outdoor use.

Can I use this card for both access control and payment on the same system?
Yes. The DESFire EV1 architecture supports multiple applications on a single card. A single credential can handle door access, canteen payment, and identity verification if the system software supports multi-application management.

How do I request a quote for a large-scale project?
Contact DO RFID Reader via email at info@dorfidreader.com with your required quantity, customization needs, and delivery timeline. A project-specific quotation and production schedule will be provided.
