Product Overview
The DO-MFCEV1-4K-CR80WH is a white NFC PVC card embedded with a MIFARE Classic EV1 4K chip, designed for secure contactless identification and data exchange. This card operates at 13.56 MHz with a read range of up to 10 cm, compliant with ISO/IEC 14443 Type A and NFC Forum MIFARE Classic standards. It provides 4 KB of memory with 7-byte UID, making it suitable for storing business card details, access credentials, loyalty points, or transit fare data. System integrators, facility managers, and project contractors choose this card for deployments requiring reliable read performance, moderate security, and cost-effective bulk procurement. The white PVC body supports custom printing, encoding, and personalization, enabling seamless integration into existing access control, payment, and identification systems. DO RFID Reader manufactures this card with stable production capacity, batch consistency, and fast lead times, ensuring long-term supply for commercial and industrial projects.
Product Advantages
Industrial buyers and distributors select the DO-MFCEV1-4K-CR80WH for its proven chip stability, ample memory capacity, and compatibility with legacy MIFARE infrastructure. The 4 KB memory enables storage of up to 32 standard data sectors, each protected by a two-key access structure, allowing system administrators to segment data for different applications on a single card. This reduces card issuance costs and simplifies credential management in large-scale deployments.

Industrial Applications
The DO-MFCEV1-4K-CR80WH is deployed across multiple sectors where reliable contactless identification and data storage are required. Typical use cases include:
- Public Transportation – Stored-value ticketing, monthly passes, and zone-based access for bus, metro, and tram systems. The 4 KB memory allows fare product data and travel history to coexist on a single card.
- Electronic Toll Collection – Prepaid toll accounts and vehicle identification for highway and parking access barriers. Cards are issued to frequent users for automatic debiting.
- School and Campus Cards – Multi-function student IDs combining library access, cafeteria payments, dormitory entry, and attendance tracking. One card replaces multiple credentials.
- Internet Cafés and Gaming Centers – Time-based access cards that store session credits, loyalty points, and membership data on the chip.
- Access Management – Employee badges for office buildings, warehouses, labs, and restricted areas. Sector-based keying enables different clearance levels per zone.
- Car Parking – Season parking passes and pay-per-use cards for commercial parking lots. Compatible with existing 13.56 MHz readers.
- Employee Cards – Corporate ID badges combining physical access, time tracking, and secure printing with cardholder data stored on chip.
- Loyalty Programs – Retail membership cards that accumulate points, redeem rewards, and store customer preference data.
System integrators value this card for its predictable reader compatibility, straightforward encoding workflow using standard NFC tools, and the ability to pre-configure sectors before bulk distribution. For large-scale rollouts involving thousands of cards, the cost per unit decreases significantly while maintaining consistent read reliability.

Frequently Asked Questions
Q: Is the DO-MFCEV1-4K-CR80WH compatible with iPhones?
A: MIFARE Classic chips have limited support on iOS. iPhones with NFC can read the UID using certain apps, but full sector read/write is not available. For full Android and iPhone compatibility, we recommend NTAG or DESFire chip variants.
Q: Can I print my company logo on this card?
A: Yes. We offer full-color offset and digital printing. Send your artwork file and we will provide a proof before production. There is no additional tooling charge for standard print runs.
Q: What is the minimum order quantity for custom printed cards?
A: The minimum is 100 cards for custom printing. For plain stock cards without printing, the MOQ is 10 cards.
Q: How are the cards shipped?
A: Cards are packed in protective cardboard boxes with internal dividers to prevent scratching during transit. Bulk orders are palletized with stretch wrap for added protection.
Q: Do you provide sample cards before bulk production?
A: Yes. We can ship up to 5 sample cards with your chosen chip and print specification for evaluation. Sample cost is invoiced separately and credited on the first production order above 500 cards.
Q: What is the typical lead time for a 1,000-card order with custom printing?
A: For 1,000 cards with full-color printing, lead time is 10–15 working days after artwork approval. Rush orders can be expedited to 7 working days subject to production schedule.
Q: Can I encode the cards myself, or do you offer encoding services?
A: You can encode the cards using any standard NFC reader/writer and available software tools (e.g., NFC Tools for Android, Windows, macOS, Linux). We also offer pre-encoding services for bulk orders where you supply the sector keys and data structure.
Q: What if I need a different chip or memory size?
A: We manufacture cards with a wide range of NXP, Infineon, and compatible chips including MIFARE Classic 1K, MIFARE Plus, DESFire EV2/EV3, NTAG 213/215/216, and ICODE SLIX. Contact us with your application requirements for chip selection guidance.
