Scan qr code for points!

MIT App Inventor Help
1

I want to make a system that gives points to users by scanning a qr code, 1 qr code scanned = 1 point.

Problems:
-I dont know how to make it
-How I create the QR codes and how to make it get scanned by a user once
-Maybe I need to connect to firebase

The ideia is that i ill put diferent qr codes in some monuments of different cities, when the user scan it, it will open the app on a special page with all the information about the monument, in the end of the page there will be button to rendeem the point. When the user reach the total points (idk how much will be, maybe 20) they will go to a tourism office to convert the points for a prize, then the person that gives the prize deletes that city points.

If you want more info tell me! :slight_smile:

  1. Learn Appinventor, do the tutorials
  2. Use one of the many online services to create your qr codes
  3. Use the BarcodeScanner component to read the qr codes
  4. Use logic to only allow the successful reading of a qr code once.

You don't really need to put up bar codes for this, if you keep a list of points of Interest in the Media folder of your app.

Sample entry:

(longitude,latitude,"ABG's apartment above a fish store when he was a kid"

Have your app guide the user to such points of interest, and log their journeys.

This called a geofence, if you are looking for a search term.

When a number of hits are reached, have the app display a code they can email to your tour sponsor.
