Product Overview

The MIFARE Ultralight C 13.56MHz MF Blank RFID NFC Printable Card is a standard CR80-sized contactless smart card designed for high-volume, low-value applications that require a balance of cost efficiency and enhanced security. Manufactured by do rfid reader manufacturer, this card integrates the NXP MF0ICU2 chip and operates at 13.56 MHz, supporting both ISO/IEC 14443-A and NFC Forum Type 2 protocols. With 192 bytes of total memory and 144 bytes of user-available storage, it provides sufficient capacity for ticketing, loyalty, access, and micro-payment use cases where data integrity and moderate security are essential. The 7-byte UID ensures reliable identification, while the 3DES authentication (112-bit encryption) prevents unauthorized cloning or data tampering. This product is supplied as a blank, printable card, allowing system integrators, distributors, and project contractors to encode, personalize, and deploy according to their specific application requirements. The card measures 85.6 mm x 54 mm x 0.8 mm and is made from durable, waterproof PVC, suitable for dye-sublimation and thermal transfer printing using standard card printers from manufacturers such as Zebra, Epson, and Canon.

Product Advantages for Industrial and Commercial Deployment

System integrators and project managers choose this card because it solves a fundamental procurement challenge: sourcing a reliable, standardized NFC card that supports 3DES authentication at a unit cost compatible with high-volume deployment. Unlike basic unencrypted NFC tags, the MIFARE Ultralight C provides cryptographic protection for stored data, making it suitable for closed-loop ticketing, loyalty point accrual, and prepaid access scenarios where counterfeiting or data modification must be prevented. The card conforms to ISO standard dimensions, ensuring compatibility with existing card printers, encoder stations, and reader infrastructure already deployed in transportation, events, hospitality, and enterprise identification systems. For distributors and wholesalers, the consistent production quality and batch-to-batch uniformity reduce field failures and support costs, which is critical when supplying cards for large-scale projects with thousands or millions of units in circulation. The 10 cm read range and 106 kbps data transfer rate are sufficient for proximity-based transactions in turnstiles, POS terminals, and handheld NFC readers.

Frequently Asked Questions

Q: What is the difference between MIFARE Ultralight C and standard Ultralight EV1?
A: The Ultralight C includes 3DES authentication (112-bit encryption), which provides cryptographic protection for stored data. Standard Ultralight EV1 cards do not support hardware encryption, making the C variant preferred for applications where data integrity and anti-cloning protection are required.

Q: Can these cards be printed with a standard card printer?
A: Yes. The card surface is blank PVC and compatible with dye-sublimation and thermal transfer printers from manufacturers such as Zebra, Epson, Canon, and similar models. The CR80 size fits standard printer feeders without modification.

Q: Are these cards rewritable after encoding?
A: Yes. The MIFARE Ultralight C memory is EEPROM-based and supports multiple write cycles. The 3DES authentication keys can be configured to allow or restrict write access depending on the application security policy.

Q: What is the minimum order quantity for wholesale pricing?
A: Volume pricing is available from 1000 pieces upward. Custom artwork and pre-encoding may have separate setup considerations. Contact do rfid reader manufacturer for a quotation based on your specific volume and customization requirements.

Q: Does the card work with all NFC smartphones?
A: The card is NFC Forum Type 2 compliant, which is natively supported by Android and iOS devices with NFC capability. Compatibility depends on the operating system and app implementation. Basic UID reading and NDEF data exchange are supported on most modern smartphones.

Q: Can the UID be changed or reprogrammed?
A: No. The 7-byte UID is factory-locked and cannot be altered. It serves as a permanent, unique identifier for each card.

Q: How should I store these cards before deployment?
A: Store in a cool, dry environment away from direct sunlight, extreme heat, and strong electromagnetic fields. Keep cards in original packaging to prevent surface scratches or contamination that could affect printing quality.

Q: Do you provide encoded cards ready for immediate deployment?
A: Yes. As part of OEM/ODM services, the factory can encode application data, write NDEF records, configure 3DES keys, and personalize cards according to your specification before shipment. Contact do rfid reader manufacturer with your encoding requirements for a custom solution.

Q: What is the expected read range in real-world conditions?
A: Read range depends on the reader antenna design and power output. Typical range in standard fixed readers is 2 to 8 cm. With optimized reader antennas, ranges up to 10 cm can be achieved.

Q: Is this card suitable for outdoor use?
A: The PVC material is water-resistant and can withstand occasional exposure to rain or moisture. However, continuous outdoor exposure to direct sunlight and extreme temperatures may cause material degradation over time. For outdoor applications, consider protective card holders or enclosures.

Q: Can I request a sample before placing a bulk order?
A: Yes. Single-piece and 10-piece sample packages are available for purchase to evaluate the card with your readers, printers, and application software before committing to larger quantities.
