What's the point of unique number? Just push everything through one card, like NAT.

When you do refunds, you want to make sure it’s going back to the same account via the same payment method. Otherwise, you’re opening yourself up to avenues of fraud.
Also helps merchants who offer refunds without receipts, as they can ensure the item was purchased from them at some point in the recent past.
