She swore that her sister would not pay for the food

Question
A woman wanted to buy food from a restaurant and swore an oath that her sister would not pay for the food, but her sister had points from a security company that she earned by topping up her balance and ordered the food and paid with these points instead of cash. In this case, does the sister who swore have to perform an expiation for her oath?
Answer
I say, and with God's help: She is required to make expiation; because the payment was confirmed by the sister, even if it was through points; because points have the ruling of money, and God knows best.
