I need application that allows users to connect to a local WI-FI router for a limited period of time (30 min). The wi-fi access is done by scanning a QR-code password. Very important: the QR code need to be automatically generated and different for each user.
Client- Server scenario:
Server: a interface with contain a button that automatically generates the QR code. An report with the number of people connected: date, time and name which can be downloaded.
Client: When scanning the QR code, the user connects to WI-FI and after 30 minutes he is disconnected. Even if it scan the same QR code again, it can no longer connect. The user needs a new QR code which will give him another 30 min of WI-FI
