The RFID modules of the TWN4 Mini reader family have been designed for integration into machines, handheld computers or any other device where small size matters. Thanks to their compact dimensions, the modules can be directly integrated into almost any host system. The host communication takes place via RS-232 or asynchronous serial TTL interface. Besides, the new EVP modules offer two LEDs that can be controlled per software. For applications requiring additional security, an external Secure Access Module (SAM) can be connected.
