13.56MHz RFID NFC Card (ISO14443A, 1KB EEPROM)

This 13.56MHz RFID NFC Card is a passive contactless card designed for wireless identification and data exchange. Operating under the standard ISO14443A protocol, it is an ideal component for students, makers, and educators developing security, tracking, or automation systems.

Standard 13.56MHz high-frequency interface

The card communicates using the standard 13.56MHz frequency and ISO14443A protocol. This makes it broadly compatible with standard RFID development modules and NFC-enabled devices.

Built-in 1KB EEPROM memory

Equipped with 1KB of non-volatile EEPROM storage, the card can store custom payloads and access records. Users can read and write data blocks directly to support varied project needs.

Fixed 4-byte unique identifier

Each card includes a 4-byte UID that provides a distinct address for contactless recognition. This fixed identifier simplifies logging, attendance tracking, and individual credential verification.

Passive maintenance-free design

Operating entirely passively, the card harvests its operational power directly from the radio frequency field of the reader. It requires no internal batteries, ensuring long-term reliability and zero maintenance.

Versatile identification and automation use

The card is tailored for contactless identification, NFC-based automation triggers, and IoT interactions. It serves as a practical tool for building smart locks, attendance systems, and automated workflows.
