Currently when checkin using QRCODE, admin user will be send to checkin completed page.
How can we add one more step to checkin?
When admin user scan the QRCODE, it will go to confirmation page with a form to fill (I plan to add comment field).
Field in form is from custom field, then after admin user fill this form, he can click the confirm checkin button.
Unfortunately, there is no easy way to do that. So if it's really needed, you will have to find a developer to customize the extension to have this feature for you. It's not possible to configure Events Booking to have it works like that
