Product Features:
1. This RFID tag supports both I2C and NFC interfaces for flexible data interaction.
2. Compliant with ISO/IEC 15693 standard, enabling wireless reading and identification by mainstream smartphones.
3. Features 16Kbit EEPROM storage for data logging and configuration storage.
4. Can function as an “I2C to RFID” transmission system to wirelessly send and receive data from mobile devices.
5. Plug-and-play design with STEMMA QT interface for rapid integration and development.
Product Description:
This RFID tag interacts with smartphones similarly to other RFID tags but can be reprogrammed via I2C. It appears as an ISO/IEC 15693-compliant (13.56MHz) chip readable by smartphones and tablets. Note: Popular RFID reader/writer chips like the PN532 do not support the ISO15693 standard. Therefore, once programmed, ST25DV tags cannot be read using these chips! This product can function as an “I2C to RFID” transmission system to wirelessly send and receive data from mobile devices (though you will need to develop a custom application for such projects).
