Using AirID

AirID FIDO supports various operating systems like Windows, MacOS (planned), Linux, iOS and Android. The basic requirement is the Bluetooth Low Energy functionality of the device. When AirID is successfully paired and the driver is installed, the FIDO Security Key is available to be used for cryptographic operations such as authentication or data encryption.

The AirID software consists of two components:

1. AirID drivers, which ensures the communication between the AirID and the operating system, must be installed additionally depending on the platform or is already integrated in the Apps and solutions of third party vendors.
2. AirID Central App - a management software for your AirID forming the basis for usage of the device. The tool provides you with information and setting options for your AirID when your reader is connected to your device. 

AirID can be used with different terminals and platforms, but not in parallel operation.
