About this product
The RDM6300 is a 125 kHz RFID reader module that reads EM4100-compatible cards and tags through an external antenna, with a reading distance of up to 7 cm. It outputs card data over a UART TTL serial interface, so it connects easily to Arduino, ESP32 and STM32 boards. Typical uses include access control and attendance systems.
