RFID Reader Serial
RFID Reader Serial
The RFID Reader Serial is a compact, low-power Radio Frequency Identification (RFID) reader module designed for various IoT applications. This serial interface-based reader is capable of reading RFID tags at various frequencies, providing a reliable and efficient way to identify and track objects.
The RFID Reader Serial module is designed to read RFID tags and transmit the read data to a microcontroller or a computer through a serial communication interface. The reader operates in a slave mode, responding to commands sent by the host device. It supports various RFID tag protocols, including ISO 14443A, ISO 14443B, ISO 18092, and more.
