POS cash-back is a retail payment feature that lets a shopper obtain physical currency during checkout. The payment instrument is charged for both the merchandise and the requested cash, which the retailer dispenses at the terminal. This meaning is separate from promotional cash-back, where a later rebate reduces the customer's effective purchase cost.
