EM-18 READER MODULE RFID SHIELD EM18 125KHZ
EM-18 RFID reader shield 125kHz for Arduino. Supports EM4100 cards and key tags for access control projects.
Description
The EM-18 RFID Reader Module Shield (125kHz) is a reliable identification and access control solution designed for Arduino and microcontroller-based projects. Operating at 125kHz, it supports EM4100/EM4001 compatible RFID cards and key tags. The shield format allows easy plug-and-play integration with Arduino boards, eliminating complex wiring. With serial (UART) output, the EM-18 RFID shield enables fast and accurate tag reading, making it ideal for access control systems, attendance management, security projects, and automation applications.
