Quick spec — MIFARE Classic 1K Wristband
Chip technical brief
MIFARE Classic 1K (NXP MF1ICS50) is a 13.56 MHz HF chip compliant with ISO/IEC 14443 Type A, providing 1,024 bytes EEPROM partitioned into 16 sectors of 4 blocks. Each sector is protected by a pair of 48-bit keys (Key A / Key B) using the proprietary Crypto-1 cipher. Crypto-1 has been considered cryptographically broken since 2008, so MIFARE Classic 1K is no longer recommended for high-security deployments — but it remains the dominant chip in legacy hotel locks, public transit (some Asian and LATAM systems), gym access and small-business membership cards because of its low cost and broad reader compatibility. RFIDAK supplies MIFARE Classic 1K cards and credentials with optional UID-only encoding, sector key personalization under NDA, or pre-encoded data block writing for system integrators replacing legacy stock.

Wristband manufacturing
RFID wristbands embed the chip + antenna inlay inside a wearable wrist-worn band. Silicone is the dominant material for reusable applications (hotels, water parks, fitness clubs) because it is waterproof (IP68), chlorine-resistant, soft against skin, and accepts CMYK silkscreen printing that survives hundreds of wash cycles. PVC and Tyvek are used for single-use event wristbands (concerts, conferences, NYE parties) where lower per-unit cost matters more than longevity. Closed-loop wristbands ship in their issued size; adjustable wristbands have a one-way ratchet snap that locks at any of 12-15 positions. Sizes are issued in adult Φ65 mm and child Φ45 mm as a default 2-SKU pair for hospitality.

- • Adult Φ65 mm closed-loop
- • Adult adjustable 180-260 mm
- • Child Φ45-55 mm
