A system for self-checkout within a store, the system having a processor and memory in a computing apparatus that: reads a customer's credit card number; uses the credit card number to check whether a transaction stored under the credit card number is for a particular store from which the customer claims to have purchased one or more products; uses the credit card number to check whether a transaction stored under the credit card number is for a particular amount equal to that of a total price plus any sales tax on items the customer claims to have purchased from the store; and uses the credit card number to check for individual products bought by the customer from a particular store in what appears to be in a single visit by the customer to the store; and verifies that a total weight of items carried out of the store by the customer for a single visit matches that of what a weight should be for all items that appeared to have been purchased in the single visit when checking individual products using the credit card number.
