No software installation is required. It can be used with NFC on the Android mobile operating system, as well as Microsoft Windows Desktop with a smartcard reader. On mobile phones, correct positioning at the back is required - either in the middle or at the very top - depending on your device model. The card is natively supported out of the box by most browsers. Websites supporting the FIDO standard include Google, Facebook, Twitter, Dropbox, Outlook, and many others.
