Abstract: PROBLEM TO BE SOLVED: To provide a method, an apparatus, a system and a computer program product for using RFID techniques for storing product information on a tag attached to a commodity. SOLUTION: The method includes (a) writing a value into a first memory 560 which forms a portion of an RFID tag and which has a length; (b) writing a form in the second memory 550 of the RFID tag: and (c) imposing access control rules on the first memory 560 in response to (a) and (b). This can prevent alteration of the stored information, tracking of customers and purchased merchandise on a global scale, and the discrepancy of prices which occurs at points of sale.
