This International Standard defines the basic features of RFID for the use in the supply chain when applied to product tagging. In particular it ⎯ provides specific recommendations about the encoded identification of the product, ⎯ makes recommendations about additional information about the product on the RF tag, ⎯ makes recommendations about the semantics and data syntax to be used, ⎯ makes recommendations about the data protocol to be used to interface with business applications and the RFID system, and ⎯ makes recommendations about the air interface standards between the RF interrogator and RF tag. This International Standard only addresses product tagging and does not address product packaging.
