Windows Certificate Propagation Service

The Windows Certificate Propagation Service is a component of the Windows Operating System that enables users to log in to their computer with Smart Cards. Very few companies and almost no individuals use this feature of Windows. When the service is running, it disrupts the communication to the NFC reader, making the GoToTags Encoder and GoToTags Windows unusable. On Windows 10 if the service is running and an NFC tag is placed on the NFC reader, you will hear a Windows beep; this is Windows trying to install a smart card device.

The GoToTags software attempts to stop this service on startup; sometimes it is unable to stop the service. Its best to disable this service manually. You may need to contact your system administrator to perform these steps.
