One card per family. Siblings scan together on the same card, and whoever is not there gets removed on the screen afterwards.
Edits and deletions sync to your Google Sheet as corrections the next time it syncs.
Cards print several to a page with dashed cut lines. Print two copies per child so each pickup adult has one.
Send a card image to a parent's phone instead of (or as well as) a printed card. They save it to their photos and show their screen at the door. Scanning from a phone screen needs an imager-type scanner or the camera button; laser scanners cannot read screens.
With this on, the back camera stays on while the kiosk sits idle and checks a child in the moment their card comes into view. No barcode scanner needed. Stand the tablet so its back camera faces where parents hold up a card. Keep it plugged in: a camera that never sleeps uses a lot of battery.

The file opens in Excel, Numbers, or Google Sheets. It includes full names.
The PIN keeps parents and kids out of these settings. It is stored only on this device.
Everything this kiosk records stays in this tablet's browser storage. Nothing is sent anywhere unless you connect your own Google Sheet above. Clearing Safari or Chrome website data erases the roster and history, so export a CSV now and then as a backup.
