Card, other methods and split payments

The payment dialog can combine methods. Selecting Card does not by itself prove that every card terminal is integrated or that a charge succeeded.

Steps

1. Open payment, check the amount due, then select each configured method and enter its amount.
2. For a total of 7.00, card 5.00 plus cash 2.00 leaves zero remaining. Non-cash amounts must not exceed the total; excess tender requiring change must come from cash.
3. Bind the correct member before using stored value. Follow chapter 018 for vouchers instead of treating them as unrestricted cash.
4. Verify external payment success before confirming the sale. Where a terminal is integrated, reconcile both its result and the software status.
5. Check the method breakdown in sales history, not only the overall amount received. Maintain method names in the relevant POS settings.
