So the keychain could contain the chip so when two keychains would come in contact with one another it would allow the both members of the platform to follow each other. When the process is successful a red light could blink from the inside of the keychain (that would look pretty cool) It would be awesome to see that in action but I think that the very simple interface for the onboarding platform is the way to achieve that as members first have to be on Hive in order for the keychain process to happen.
