EM 18 RFID Reader Module

EM 18 RFID Reader Module The EM-18 RFID Reader Module is a compact and reliable 125KHz RFID reader designed for contactless identification and access control applications. It can read the unique ID number from standard 125KHz RFID cards and key fobs and outputs the data through TTL serial interface, making it easy to connect with microcontrollers such as Arduino, PIC, AVR, Raspberry Pi, and other embedded systems.The module comes with a built-in antenna and supports plug-and-play operation. When a compatible RFID tag is brought near, the EM-18 reads the card ID and sends it automatically to the host controller. Due to its simplicity, stability, and low cost, it is widely used in security systems, attendance systems, and DIY electronics projects.Click here to view related productsFeaturesOperating Frequency: 125KHzReads standard 125KHz RFID cards and key fobsOutput Interface: TTL Serial (UART)Built-in antennaFast reading speed and stable performanceContactless operationLow power consumptionCompact and lightweight moduleLong reading life and reliable performanceEasy to interface with Arduino and other microcontrollersApplicationsAccess control and door lock systemsAttendance and time tracking systemsSecurity and authentication systemsStudent and employee ID systemsParking and gate control systemsEmbedded and Arduino projectsHome automation and smart security systemsDIY RFID-based projectsEM18 Datasheet*Product image for illustration purposes only, actual product may vary.
