WiKID tokens communicate with your WiKID server using their asymmetric keys.
The WiKID Administrator creates a Domain identifier/Server Code that the tokens use to find the server. It is the zero-padded IP address of the WiKID server. There is no need to keep this information secret. It's just an IP address after all.
You can test this on a token by adding this domain: 054198073183. Software tokens are available on the Android Play and Apple iTunes store or you can get a PC token.
When the user hits 'Continue' their public key is sent to the WiKID server. The server responds with its public key and a configuration file and asks the user to set their PIN.
