Can adorers check in with a mobile device?
There's a special Mobile Check-In QR Code that administrators can print and post in the adoration chapel.
Visit Admin » Settings » Attendance, and make sure that the Adoration Check-In Kiosk is enabled.
The QR code is displayed under the Mobile Check-In heading.
The default QR code is for English-speaking adorers. Click the Spanish tab to see the QR code for Spanish-speaking adorers. Consider including both of these images in whatever instructions you print.
Note: If you change the kiosk password, you'll need to print the newly-generated QR code.
