The SIFER card reader is a Smart Card reader designed and manufactured by Inner Range. It is a multi-drop RS-485 based reader that employs 128 bit AES encryption from the card through to the door module, providing a far superior level of security than that of traditional Wiegand based card readers. SIFER readers utilise the Mifare DESfire EV1 card format.

As SIFER readers utilise a superset of the OSDP protocol, the readers may also be deployed on any system capable of using OSDP. Up to 16 SIFER readers may be connected in series to the dedicated RS-485 reader port on the Integriti Intelligent LAN Access Module (ILAM) or the new Integriti Access Controller (IAC) for full Reader-In and Reader-Out operation. Up to 4 SIFER readers may be connected to the Integriti Standard LAN Access Module (SLAM). SIFER readers are IP 67 rated and available with site specific encryption keys.

The SIFER Multi Format Card reader offers an identical set of features to the standard IR-994720 SIFER reader with additional support for reading the CSN of third party 13.56Mhz credentials.
