Electronic key reader

Quick and easy: to open the door, all you have to do is hold a Siedle transponder near the reading field. If it is lost, it is sufficient to delete the code.

Siedle USB-Reader readID One

Fast reader: USB reader readID One

Connected to a computer in Plug+Play mode, the readID One USB reader reads transponder data in a matter of seconds. This data is compatible with all common word processing programs and operating systems. This saves time when managing users, access profiles and RFID devices. This is particularly helpful in buildings that many people have access to.

To the product data

Open to the best solution: connecting components

Siedle Secure is as varied as the requirements of the building in which it is installed and as individual as the owner's wishes. A range of features and systems – including from other manufacturers – can be connected via its API interface or the Open Supervised Device Protocol (OSDP).

Service from the cloud

Networked with the cloud, a Siedle access control system offers convenient service features, such as booking of guest apartments or meeting rooms.

Smart locks. Smart access.

Smart locks are read devices and door openers in one. Integrated in Siedle Secure, they are ideal for transition points in buildings – such as storey doors or access points to underground garages.

Combine an RFID and keypad

If different access mechanisms are to be offered, combi devices made up of electronic key readers and code locks are useful. This is connected to Siedle Secure via the API interface.

Service throughout all project phases

Our specialists for Siedle Secure are here for you when you need us: during project planning, system design, installation and maintenance or expansion.
