Description
13.56 MHz RFID Card
This contactless RFID card is listed for use with compatible 13.56 MHz readers such as the RC522. Choose a color from the available variants. The exact chip, memory capacity and supported commands depend on the card supplied; confirm compatibility with your reader and software.
🔧 Listed specifications
- RF frequency: 13.56 MHz
- Listed data rate: 106 kbit/s
- Standard stated by the listing: ISO/IEC 14443
- Colors: orange, pink, purple, green, blue, red, yellow, black and gray
- Listed read/write distance: 2.5–10 cm; actual range depends on card, antenna, reader tuning and surroundings
The source’s storage-sector, erase-cycle and retention claims depend on the exact card IC and product version; they are not guaranteed here as universal values. The MFRC522 reader supports ISO/IEC 14443 Type A/MIFARE-family communication, but that does not make it compatible with every 13.56 MHz card or protocol.
⚙️ Compatibility and use
Present the card near a compatible reader antenna and use software/library support for the specific card IC. A 13.56 MHz frequency match alone is not enough: protocol, card family and command support must also match.
Security note: a card UID is generally an identifier, not a secret credential. Do not rely on UID-only checks for real access control or valuable assets. Use a secure card technology and cryptographic authentication appropriate to the application.
