NFC Label NXP MIFARE Classic® EV1 | ISO14443A | 55 x 18mm
The ForNext 55 × 18 mm NFC label is powered by the NXP MIFARE Classic® EV1 1K chip, commonly referred to as S50. It is available with either a 4-byte NUID or a 7-byte UID, depending on the selected chip version.
Operating at 13.56 MHz and compliant with ISO/IEC 14443 Type A, the label supports fast contactless communication at a data transfer rate of 106 kbit/s.
The chip provides 1 KB of EEPROM, organised into 16 sectors. Each sector contains four blocks, with 16 bytes per block. This sector-based memory structure is suitable for applications that require separate data areas, access keys or stored-value records.
MIFARE Classic® EV1 uses the proprietary MIFARE CRYPTO1 security mechanism, together with anti-collision support, 16-bit CRC, parity checking, bit coding and bit counting for reliable communication. Typical ticketing transactions can be completed in under 100 ms, including backup management.
The 55 × 18 mm label format uses a 52 × 15 mm inlay, providing a slim rectangular shape suitable for cards, badges, tickets, packaging, plastic surfaces, documents and other non-metallic items.
Typical applications include:
- Access control and identification – use with compatible legacy systems for staff, visitor, locker or facility identification.
- Ticketing and transport systems – support fast contactless transactions for compatible event, fare collection and transport applications.
- Loyalty and membership – store customer IDs, membership references, points or other application-specific records.
- Attendance and time management – identify staff, students, contractors or visitors in compatible check-in systems.
- Cashless and stored-value applications – support closed-loop payment, vending, catering or campus systems using compatible MIFARE Classic® infrastructure.
- Asset and workflow identification – assign contactless IDs to equipment, documents, containers or internal process items.

The 55 × 18 mm NXP MIFARE Classic® EV1 1K label is suitable for established access control, ticketing, loyalty, attendance and closed-loop identification systems that already support MIFARE Classic® technology.
MIFARE Classic® EV1 should not be positioned as a high-security NFC solution. For applications requiring modern cryptographic authentication or stronger protection against cloning, a MIFARE DESFire® solution may be more appropriate.
For use directly on metal surfaces, a specialist on-metal HF label construction is required. Custom materials, adhesives, printing and data encoding are available.
