I’m developing an event system that will consist of a web system and a mobile app. One of the main points will be the accreditation (check-in and check-out) of the users in the lectures. After a registration on the site and registration for the event, on the arrival of this user at the site of the lecture I intend to confirm his presence in the lecture in some way. I need some idea how to do that. Generate a barcode for each event and read it on the user’s badge when it arrives at the event? Using Qrcode and the user’s mobile phone? Does each event have an identification 'code'? So how to prevent users who have not been to the talk from not having the presence confirmed by other people? Suggestions please.
You can read the Qrcode of the identification badge in the lobby.

I would bet on a Qrcode. In the talk can have a Qrcode and the user when it arrives reads the Qrcode with the application. This Qrcode forwards to a URL that validates the entry in the event. This is an example among many others that you can do
