Systems, apparatuses and methods for deterring product theft and preventing the fraudulent return or exchange of products. Products are associated with a Radio-Frequency Identification (RFID) tag. Tag readers located at store access points can detect the presence of the RFID tag and can be used to help determine a direction of travel of the RFID tag. When a product is determined to be leaving the store, the transaction history of the product can be accessed, as well as the supply chain history of the product, to confirm the product has been validly purchased and therefore authorized for removal from the store. When a product is determined to be entering a store, the supply chain history and transaction history of the product can be consulted to determine if the product can be validly exchanged or returned.
