Product Overview

The MIFARE DESFire Light chip embedded in a white PVC card delivers a purpose-engineered NFC solution for system integrators, access control contractors, and commercial deployment projects requiring balanced security and memory at a controlled unit cost. This card operates on the ISO/IEC 14443 Type A standard and supports ISO/IEC 7816-4 commands, ensuring compatibility with existing reader infrastructure and NFC-enabled mobile devices. With 640 bytes of memory, an AES 128-bit cryptographic engine, and support for multiple encryption schemes including Single DES, 2KTDEA, 3KTDEA, and AES128, this card is suited for environments where data protection and reliable identification are mandatory. The 7-byte UID and compliance with NFC Forum Type 4 allow seamless interaction with Android and iOS devices through tools such as NFC Tools.

Procurement teams, facility managers, and project planners select this card when they need a field-proven identification medium that integrates directly into existing access control, ticketing, or membership systems without requiring custom hardware adaptation. The 200,000 write cycles and 10-year data retention provide operational longevity for recurring use cases such as daily access or frequent transactions. The minimum order quantity of 10 units and stock level of 518 units support both pilot testing and staged rollout. For larger deployments, volume pricing from 20 to 1,000 units offers predictable cost scaling during project expansion.

Product Advantages

System integrators and distributors choose this card because it solves a recurring commercial problem: deploying secure contactless identification across multiple applications without managing separate cards per function. The MIFARE DESFire Light chip supports an unlimited number of applications within a single card, so one card can handle building access, cafeteria payments, event ticketing, and printer release in a corporate campus or amusement park setting. This reduces administrative overhead for end users and lowers inventory complexity for resellers.

For wholesalers and bulk buyers, the advantage lies in batch consistency and stable supply. DO RFID Reader manufactures these cards from virgin PVC with consistent thickness and edge finish, so large batches maintain identical electrical characteristics across all units. This matters when deploying 500 or 1,000 cards into a single project where every card must perform identically at every reader point. The 13.56 MHz operating frequency and reading distance up to 10 cm allow reliable capture even when cards are kept in wallets or badge holders, reducing user friction at entry points.

Key Features

• Security Architecture: AES 128-bit hardware cryptographic engine protects transmission data with encryption and integrity verification, supporting Single DES, 2KTDEA, 3KTDEA, and AES128 key schemes.

• UID Structure: 7-byte unique identifier provides a large addressing space for system-level card tracking and anti-collision handling.
• Durability: 200,000 write cycles and 10-year data retention ensure the card remains operational through years of daily use in access control or ticketing workflows.
• Standards Compliance: ISO/IEC 14443 Type A and NFC Forum Type 4 guarantee interoperability with standard off-the-shelf readers and mobile NFC hardware.
• Physical Construction: White PVC card in rounded rectangle shape, 85.5 mm x 54 mm, 6 g weight, with operating temperature range from -25°C to 85°C for indoor and sheltered outdoor use.

Industrial Applications

The MIFARE DESFire Light PVC card supports practical use cases across several commercial and institutional segments:

• Amusement Parks and Water Parks: One card holds season passes, stored value for food and merchandise, and fast-pass access. The unlimited application architecture allows operators to add or revoke services without card replacement.
• Corporate Office Buildings: Employees use the same card for door access, parking entry, cafeteria payment, and printer authentication. System integrators can deploy a single card policy across multiple departments with different access zones.
• Festivals and Events: Temporary event staff receive cards pre-loaded with access credentials and cashless wallet balances. The 200,000 write cycle rating supports multiple top-ups during multi-day events.
• Hotels and Resorts: Guest room access, pool entry, gym check-in, and on-site retail payments run on one credential, reducing front desk workload and improving guest experience.
• Retail and Loyalty Programs: Membership cards with encrypted data storage protect customer points balances and personal information while enabling fast tap-and-go transactions at point of sale.
• Stadiums and Arenas: Season ticket holders receive cards that combine seat access, concession payments, and parking privileges. The 7-byte UID allows large-scale patron databases without identifier collisions.
• Smart Campus Deployments: Universities use one card for dormitory access, library borrowing, event attendance, and meal plans across multiple buildings and departments.

OEM / ODM Manufacturing Support

DO RFID Reader operates as a manufacturer with dedicated OEM and ODM capabilities for organizations that require customized PVC cards for branded deployments. When a distributor or project contractor needs cards printed with a corporate logo, specific artwork, or a customized chip initialization configuration, the factory supports those modifications from the production line. Custom chip personalization, including pre-loaded keys, application directory structure, and UID allocation, is handled during the manufacturing phase so that received cards are ready for immediate deployment without field programming.

For ODM projects, the factory can adjust card dimensions, color, material finish, and chip placement to meet specific mechanical or aesthetic requirements. This is relevant for clients who integrate the card into a proprietary ecosystem and need the physical credential to match their hardware design guidelines. The production line supports both small-batch qualification runs and full-volume manufacturing, so OEM partners can validate prototypes before committing to large quantities.

Factory Production Advantages

The production facility maintains stable capacity for continuous card output, which is a practical requirement for clients who place recurring monthly or quarterly orders rather than one-off purchases. Raw PVC stock is held in sufficient volume to cover standard production runs without material sourcing delays. Chip supply is managed through established component procurement channels, ensuring that MIFARE DESFire Light chips are available even during market allocation periods.

Quality inspection procedures include visual surface inspection, electrical parameter verification, and read/write cycle testing on sample cards from each production lot. This prevents delivery of cards with misaligned chips, incomplete antenna windings, or inconsistent thickness that could cause reader communication failures. For export orders, cards are packed in anti-static trays and sealed cartons with labeling that supports customs clearance and warehouse receiving verification.

The minimum order quantity of 10 units allows new clients to evaluate the card in their specific reader environment before scaling to wholesale volumes. Batch consistency is maintained through controlled production parameters, so cards ordered this month perform identically to cards ordered six months later — a critical requirement for system integrators who deploy in phases and need matching credentials across all project stages.

Bulk Supply & Project Deployment Support

Volume pricing is structured to support staged project deployment:

For system integrators managing multi-site rollouts, the ability to order 500 or 1,000 cards from a single production run ensures that all sites receive matching credentials with identical electrical and mechanical properties. This eliminates the compatibility testing that would be required if cards were sourced from different production lots or different suppliers.

Wholesale buyers and distributors benefit from predictable lead times. Standard orders up to 1,000 units can be produced and shipped within a defined production window, supporting just-in-time delivery schedules for resale or project installation. Technical support is available for integration questions, including reader compatibility verification and application directory setup guidance.
