Fudan F08 Round 25mm MIFARE Classic 1K Compatible Wet Inlay [F08-F22]

The Fudan F08 Round 25mm MIFARE Classic 1K Compatible Wet Inlay (Model: F08-F22) is a high-security High Frequency (HF 13.56 MHz) RFID transponder label powered by the Fudan Microelectronics FM11RF08 integrated circuit. Fully compatible with the industry-standard NXP MIFARE Classic 1K (S50) architecture, this inlay is engineered for campus access control, employee attendance turnstiles, corporate cashless canteen systems, hotel smart locks, and closed-loop payment cards.

1. 1KB Memory Architecture & Cryptographic Security

Operating under the ISO/IEC 14443 Type A protocol at a high-speed communication rate of 106 kbit/s, the FM11RF08 silicon chip features 1,024 bytes (8 Kbits) of EEPROM memory organized into 16 independent sectors (4 blocks of 16 bytes per sector). Each sector is independently secured by dual 48-bit cryptographic keys (Key A and Key B) and programmable access condition bits utilizing the CRYPTO1 stream cipher. This enables multiple independent applications (such as building access, parking validation, and cafeteria payments) to coexist securely on a single sticker.

2. High-Precision 22mm Antenna & Robust Inlay Construction

The F08-F22 inlay features an optimized 22.0 mm etched aluminum antenna coil within a 25.0 mm circular die-cut footprint, delivering a solid read distance of 2.0 cm to 5.0 cm on standard ISO 14443A readers and wall-mounted access terminals. Built on a 50µm PET substrate with high-strength permanent pressure-sensitive acrylic adhesive, it attaches easily to employee badges, plastic keyfobs, asset surfaces, or event wristbands.
