Most churches never need to change these. Open them from Settings → Check-in.

Check-in level
Pick Standard or Stricter. A level sets sensible QR code timing for you. Stricter makes it harder for someone to check in from an old photo of the screen. If you change the timing yourself under Advanced, you'll see that you're using custom timing — pick a level to go back to a preset.
Repeat check-ins
Choose how long Steadyfaith ignores a second check-in from the same person: 15 minutes, 30 minutes, 1 hour, 2 hours, or the whole service. This stops someone being counted twice if they scan again.

Adds a quick, usually invisible check that a real person is filling in the form. Leave it on unless guests tell you the form won't submit.

Turn this on to show a gentle invitation to give after someone checks in. Choose your church's default fund — if an event has its own fund, that's used instead. Giving needs to be set up first. Set up online giving
Advanced: QR code timing
Only for screens that show a refreshing QR code. You can set how often the code changes, and how long a scanned code keeps working — longer gives slow phones time to open the page.
