Technical Specifications

Industrial Applications

The DESFire EV3 4K card is deployed across a wide range of commercial and government sectors:

• Access Control – Corporate offices, data centers, laboratories, and government buildings require credentials that prevent unauthorized entry and support multi-zone permissions.
• Payment Systems – Cafeterias, vending machines, and transit systems benefit from encrypted transaction data and fast read speeds at point-of-sale terminals.
• Government Identification – Employee badges, national ID programs, and healthcare cards demand EAL5+ certified secure elements to protect personal data.
• Hotel and Hospitality – Guest room keys, facility access, and membership cards can be managed from a single credential with multiple application partitions.
• Parking and Logistics – Vehicle identification, gate access, and asset tracking in restricted areas require reliable read performance and tamper-resistant encoding.
• Mobile Payments and NFC Services – NFC Forum Type 4 compliance enables integration with smartphone-based credential issuance and contactless transactions.

System integrators and project contractors rely on this card for deployments where credential lifecycle management, encryption standards, and reader compatibility are contractual requirements.

OEM / ODM Manufacturing Support

do rfid reader manufacturer offers comprehensive OEM and ODM services for the DESFire EV3 4K card. Buyers who require custom chip programming, pre-encoded application directories, or proprietary encryption keys can submit their specifications for production. The factory supports:

• Custom UID ranges and pre-encoded memory structures
• Application-specific file system setup based on buyer project requirements
• Custom card artwork, including offset printing, silk-screen logos, and barcode or QR code integration
• Bulk encoding of diversified keys for access control or payment systems
• Packaging customization, including individual polybagging, bulk boxes, or retail-ready packaging

OEM partners and distributors benefit from dedicated production lines that maintain batch-to-batch consistency, reducing field issues during large-scale rollouts.

Factory Production Advantages

As a manufacturer with dedicated RFID card production lines, do rfid reader manufacturer provides supply chain stability that project-based buyers depend on. Key production capabilities include:

• Stable Production Capacity – Monthly output supports orders ranging from hundreds to hundreds of thousands of cards, with no interruption during peak demand periods.
• Batch Consistency – Each production batch undergoes antenna tuning verification and read range testing to ensure uniform performance across the entire order.
• Quality Inspection – Cards are visually inspected for surface defects, dimensional accuracy, and chip functionality before packaging.
• Fast Lead Time – Standard blank card orders ship within 5–7 working days; custom encoding and printing orders are scheduled based on complexity but typically complete within 10–15 working days.
• Export Experience – The factory ships to distributors and system integrators across multiple regions, with documentation support for customs clearance and compliance.

Bulk Supply & Project Deployment Support

Wholesale buyers and large-scale project teams require predictable supply and competitive pricing. do rfid reader manufacturer structures its pricing to reward volume commitments while maintaining technical consistency across all units.

For distributors and project integrators ordering above 1000 units, custom pricing and production scheduling can be arranged directly. Long-term supply agreements ensure that recurring deployments receive guaranteed allocation and stable unit costs.

Technical support is available during the integration phase, including chip memory mapping, reader compatibility testing, and encoding workflow guidance. This reduces deployment risk for contractors who are rolling out credentials across multiple sites simultaneously.

Frequently Asked Questions

What makes the DESFire EV3 4K card suitable for access control systems?
The card offers AES-128 encryption, mutual authentication, and EAL5+ certification, which prevent credential cloning and unauthorized data access. It also supports up to 28 independent applications, allowing a single card to manage multiple doors, zones, and time schedules.

Is the DESFire EV3 card compatible with existing DESFire EV2 infrastructure?
Yes. The DESFire EV3 is functionally backward compatible with DESFire EV2, EV1, and D40 generations. Cards can be deployed on existing reader networks without hardware upgrades, making them ideal for phased credential refresh projects.
