Short answer
Point of sale (POS) is the place and system where a retail transaction is completed, such as a checkout register or payment terminal. POS systems record what was sold, when, where, and at what price. That transaction data feeds inventory management, sales reporting, and the closed-loop measurement used in retail media and trade marketing.
