NXP MIFARE Ultralight Series Card

NXP MIFARE Ultralight Series — Cost-Effective NFC Cards & RFID Paper Tickets

The NXP MIFARE Ultralight family is the global standard for high-volume, cost-sensitive contactless deployments. Designed specifically for limited-use applications, these 13.56 MHz NFC Forum Type 2 Tag ICs deliver reliable contactless performance with a compact memory architecture, significantly lowering the per-unit cost compared to high-capacity smart cards.

As a certified smart card OEM/ODM manufacturer, Union Smart produces a versatile spectrum of MIFARE Ultralight products — ranging from standard ISO CR80 plastic cards and eco-friendly recyclable cards to continuous-roll RFID paper tickets engineered for automated transit ticketing vending machines (TVM) and high-throughput event turnstiles.

📐 Engineering & Chip Family Comparison

Union Smart manufactures cards and inlays across the complete genuine NXP MIFARE Ultralight silicon portfolio:

• MIFARE Ultralight EV1 (MF0UL11 / MF0UL21): Available in 48-byte (12 user pages) and 128-byte (32 user pages) configurations. Features a 32-bit password protection mechanism with an attempt counter, lock bits, and 3 independent 24-bit one-way event counters. The industry benchmark for disposable public transport tickets and exhibition day-passes.
• MIFARE Ultralight C (MF0ICU2): Offers 192 bytes of total memory (144 bytes user memory) with cryptographic 3DES mutual authentication. Ideal for entry-level anti-cloning security in multi-day festival credentials and closed-loop prepaid tokens.
• MIFARE Ultralight AES (MF0AES): Features hardware-accelerated AES-128 encryption, Secure Unique NFC (SUN) dynamic message authentication, and dynamic CMAC verification on each tap. Provides strong defense against cloning and replay attacks without requiring high-cost microcontroller cards.
• MIFARE Ultralight Nano (MF0UN00): Ultra-compact die footprint with 40 bytes of user memory, optimized for ultra-low-cost paper tickets, smart labels, and mass-market print advertising.

❓ Frequently Asked Questions (FAQ)

Q1. When should an enterprise select MIFARE Ultralight over MIFARE Classic?

MIFARE Ultralight is specifically optimized for cost-sensitive, limited-use, or single-trip applications like event passes, exhibition badges, and transit tickets. If your system requires frequent daily rewrites over several years, MIFARE Classic (1KB/4KB) or DESFire is recommended; for disposable or high-volume ticketing, Ultralight offers superior cost efficiency.

Q2. Can MIFARE Ultralight cards be read by standard smartphones?

Yes. The entire Ultralight family adheres to the NFC Forum Type 2 Tag specification and can be read by NFC-enabled iOS and Android smartphones, making them ideal for consumer engagement, smart posters, and digital verification.

Q3. What is the difference between MIFARE Ultralight EV1, C, and AES?

Ultralight EV1 provides cost-effective non-cryptographic memory with password protection and hardware counters. Ultralight C introduces 3DES cryptographic authentication, while Ultralight AES provides advanced AES-128 cryptographic encryption and dynamic CMAC message signing to prevent cloning.

Q4. Can Union Smart manufacture these as continuous-roll paper tickets?

Yes. We produce MIFARE Ultralight inlays converted into direct thermal paper tickets, fanfold tickets, and rolls compatible with major transit Ticket Vending Machines (TVM) and high-speed ticketing printers.

Q5. What customization and data encoding options are available?

We provide full OEM services: CMYK offset printing, spot UV, thermal serialization, barcode/QR printing, custom antenna dimensions, pre-programmed NDEF URLs, and secure AES key provisioning.
