RFID reader integration via Ethernet port

Introducing the TCP3 Authentication / Release Station From secure printing to kiosks to industrial robotics, TCP3 enables user authentication and access control for devices lacking a USB port. ELATEC introduces the TCP3 authentication/release station, a small network appliance that enables devices without a USB port to incorporate an RFID or biometric reader, PIN pad or other form of user authentication and access control, and which supports USB 3.0 and gigabit Ethernet networks. “The TCP3 station was designed to minimize information technology support costs associated with additional IP or MAC addresses while consuming only one network drop from its Host port,” said Kenneth Buck, Solutions Architect for ELATEC.
