Should I buy different media for my reward cards vs. my tender cards?
We strongly recommend it. Even though tender cards and rewards cards use the same type of media, they operate quite differently, and it is important for both you and your customers to be able to distinguish between them.
If for some reason you must use a tender card as a reward card, please consider identifying the reward card with some permanent mark, such as an unusually shaped hole punch.
What if somebody returns an item?
If the item was bought with rewards, the rewards will be returned to the rewards card of the customer returning the item. If the item earned rewards, the rewards will be removed from the card they were awarded to.
Whatever effect the sale had on rewards will be undone.
