- Decide on a secret key (skey) and an destination link (fl)
- Use those two parameters to make a new QR code in the format of "Https://attendance.masonhackclub.com/?skey={YOUR_SECRET_KEY}&fl={YOUR_FINAL_LINK_DESTINATION}"
- Have people scan the QR code and sign in with their google account
- View results via Firebase's DB. They will be related by skey and will require a bit of synthesis on your part.
