I noticed on the check-in screen that the box for parents to click for two claim receipts calls them "check-in receipts". On the receipt itself it says "Guardian Receipt". It'd be nice if they were called the same in both places. It seems "Guardian Receipt" is a little more accurate for what it's used for.
Originally they were both called "Check-in" Receipts, but we changed the name of the printed one to say "Guardian Receipt". I'll add a change request for the name in the check-in screen.
