Description
13.56 MHz RFID Card, 1 KB EEPROM
This contactless card is listed for use with compatible 13.56 MHz RC522/MIFARE Classic readers. Its exact chip revision and compatibility should be confirmed with the card supplier and the reader/software documentation.
🔧 Listed specifications
- RF frequency: 13.56 MHz
- Memory: 1 KB EEPROM; the listing states 768 bytes are available for user data
- Organization stated for the 1 KB card: 16 sectors, with 4 blocks of 16 bytes per sector
- Data rate: 106 kbit/s for compatible MIFARE Classic communication
- Card dimensions: 85 × 54 × 0.9 mm
- Material: PVC; the listing describes the card as waterproof, but provides no immersion/IP rating
- Standards stated by the listing: ISO/IEC 14443 Type A
- Listed read distance: 0–10 cm; actual range depends on the reader antenna, tuning, alignment, card and surroundings
- Write endurance: the listing states 100,000 cycles; the exact card IC and conditions determine actual performance
⚙️ Compatibility and use
Present the card near a compatible 13.56 MHz reader antenna and use software that supports its card family. Matching the frequency alone does not ensure compatibility: protocol, chip variant, authentication and commands must also match. The listed 1 KB layout is characteristic of MIFARE Classic 1K, but the exact supplied chip is not independently identified in the listing.
Security note: a card UID is an identifier, not a secret. Do not rely on UID-only checks for real access control or valuable assets. Confirm the card’s security properties and choose a suitable authentication system for the application.
