Request yours today!

The TwistyWriter-IP PC/SC is a RFID HF/NFC coupling device on your TCP/IP LAN network. It has a RJ45 10/100Mbps standard port. As it is supported by PC/SC drivers, the software integration and the application development are thus really easy.

The TwistyWriter-IP PC/SC is based on the same module as the FunkyGate-IP PC/SC.

TwistyWriter-IP PC/SC: RJ45 10/100Mbps connexion, 9 to 12V external power

TwistyWriter-IP+POE PC/SC: power-over-Ethernet RJ45 10/100Mbps connection. That means that the network cables carry electrical power.

The board measures 69x45mm (dimensions shared by most of SpringCard OEM products).

The TwistyWriter-IP PC/SC must be associated with a symmetric (balanced) antenna depending on your size constraints and on the type of tag to support.

Your contact will guide you to the antenna and ribbon cable you need. See here our off the shelf antennas. Our engineers also design custom antennas.
