13.56 MHz RFID Mullion Reader

The Mullion reader integrates effectively with our PROS CS client server software and EWS controllers, supporting 13.56 MHz credentials and communicating via standard Wiegand protocol.

The configuration and the firmware update can be done using our PROS CS software via the USB-C input on the back of the reader or with a programming card.

The XPM products are coming with the Xsecure® key, but only products ending in -X are coming with the Xsecure® configuration by default to ensure data protection.

Xsecure Solution

The Xsecure solution is based on the concept of writing the identifier as data on pre-coded MIFARE® DESFire® EV3 13.56 MHz cards.
Xsecure enables each card access key to be distinct and unique, produced through an irreversible diversification process. As a result, the data on the card is encrypted and sealed again, with an error checking against spoofing.
Only the reader and the production card encoding system are aware of this operation.
XPR encodes the cards and validates the identifiers issued to avoid duplication.

Front Tricolour LED

The state of the reader is displayed by a front triolour LED. When the card or key fob is presented, the LED transitions from blue to green if the access is granted, or from blue to red if it is denied. A prominent blue LED illuminates when the reader is connected and ready to receive credentials (idle mode).

Mullion Reader

The XPM-MF-W / XPM-MF-W-X features a slim and narrow design, making it ideal for door frames or mullions with limited space.
Mullion readers are a practical solution for access control in areas with limited mounting space, providing security and convenience without compromising the design aesthetics of the entryway.


The XPM-MF-W and XPM-MF-W-X read Mifare CSN, DESFire and Xsecure credentials with a read range of up to 9 cm.

Plug and Play

The Xpro readers' Plug and Play system simplifies installation and offers secure and flexible access management options. The readers are pre-configured and ready to connect with the solution of your choice. This saves both time and resources when implementing the access control system.
