13.56 MHz RFID Keypad

The RFID keypad is compatible with our WS4 Web server controller.

It can read 13.56 MHz credentials and communicate with our custom RS-485 protocol.

Identifiers, communication protocol and firmware updates can be configured using our XPR Product Manager software via the micro-USB input on the back of the reader or with a programming card.

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.


XS-K-MF-RS and XS-K-MF-RS-X read Mifare Classic, Ultralight and DESFire credentials with a read range of up to 6 cm.

Backlight keypad

The XS-K-MF-RS and the XS-K-MF-RS-X are equipped with an orange backlight.
The keypad changes its backlight color when the code or card is presented: from orange to red if the access is denied or from orange to green if the access is authorized. The orange backlight indicates that the keypad is connected (idle mode).
