Nothing yet: capture on an event asks on a scan, not on a quantity change.
Limits
- Today the check before payment can refuse the sale at Pay (the card line-quantity-cap).
Tell the customer
The till cannot yet ask when a quantity changes; it can stop the sale at Pay.
What next
- Ask for it: the extension-point request for P-CAPTURE3 (members only; how requests work).
- Until then, today: the check before payment can refuse the sale at Pay (the card No more than 50 of one item on a line).
