Abstract: A method, apparatus or system confirms a customer transaction by using a computer having a processor, a memory and a communications interface. A transaction data generated by a point-of-sale device physically located at a merchant is received via the communications interface. The transaction data includes a merchant identifier, a first customer identifier, a transaction amount and a first date/time. A customer location data generated by a customer mobile device physically located at the merchant is received via the communications interface. The customer location data includes a second customer identifier, a location information and a second date/time. A customer transaction confirmation is generated whenever the transaction data matches the customer location data, and one or more actions are performed based on the customer transaction confirmation.
