We already have a working prototype with the following features:
- recognises people with and without smartphones around the user using a sophisticated neural network
- works offline and 100% p2p, without the need of a back end
- data is persisted on the device and can only be shared with the consent of the owner
- data format is universally known, only needs translation of date-format and the word "contact"
We shared some images of the UI here: https://twitter.com/zenturee/status/1260830223546961920?s=20
Contact me, if you are interested.
