Hi all,

I was wondering if there is a way to identify a user across multiple LN requests or even authenticate the user in a single step using a LN wallet.

Some use cases.

* A company advertising a pay-per-view event could make billboards/posters with LN QR-codes. By scanning the code on the billboard the user would buy the right to see the event later that night. This would happen in just one step, no need for login, just like a regular LN payment.
* A music-streaming company could print QR-codes on posters. By scanning the code the user would imediately get the album on the music-streaming app on his phone.
* A user could anonymously get frequent-user discounts or reward points on vending machines or similar services.
* An arcade game like this one (https://www.youtube.com/watch?v=U0KUNbjFZdk) could identify the user across multiple plays and different machines and provide the user with high-scores and user performance statistics.
* Arcade games could provide multi player gaming keeping user identity, scores, in-game items, etc...

Is this currently possible?

Thank you,
João Joyce
