ELATEC TWN4 MultiTech 2 LF HF RFID Read/Write Module

The ELATEC TWN4 MultiTech 2 LF HF is a compact and versatile RFID reader/writer module that supports both Low Frequency (125 kHz) and High Frequency (13.56 MHz) transponders. Designed for integration into a wide range of applications, this PCB module offers multiple host interfaces including USB 2.0, RS232, SPI, and I2C, making it ideal for access control, identification, and NFC-enabled systems.

Advantages

Dual-frequency support allows seamless reading of LF and HF tags, including MIFARE, DESFire, FeliCa, and EM4100. The integrated antenna and field-upgradeable firmware ensure long-term flexibility. With low power consumption (typ. 70mA) and a wide operating voltage range (3.3V-5.5V DC), it is suitable for battery-powered and fixed installations alike. The module also features two LED indicators and a built-in buzzer for user feedback.
