Before we start, here are some pics of the UI of the app we are building, this may help you to understand what is going on.

Default(No Internet) Scanner Details Loaded

To implement the QR Scanner I used the zxing library, which is the best way to do it,as per me.

The code to this is at

Leverages google form with help of firebase cloud function to be a complete event management platform

The problem formiQR solves

If you have been to any hackathon or similar event, there the initial time is wasted in registration desk, where we need to say our name and then they go around searching it up. But with formiQR it happens in an instant with a QR scan, plus it works alongside google form, what can be more awesome than that 😄

What is formiQR ?

Overall Idea

  • First the user fills in the google form and instantly receives a QR code with an onboarding email.
  • During the event day, user shows the QR to the organizer to confirm the presence.
  • The organizer can see the real time statistics of the attendee present in the venue, with the specific details filled in the form initially, like age group, gender, grade,etc.

Why

You should have a look at the structure of Realtime Database, this may be helpful

If you are new to firebase and android, you can lookup how to connect them both, there is already more than enough content regarding this topic.
