A product information tag, typically for a medical product such as a drug or device, is prepared in accordance with various rules. The product information tag is associated with the product as it travels from a product distributor to a shipper, to a customer such as a doctor and possibly even to a patient. When the product information tag is created, a database record for the product is also created. As the product passes into the possession of different parties, the database record is updated with information regarding the location and usage of the product. Different field devices, possessed by different parties such as the shipper or the doctor, are able to read the product information tag to obtain additional information relating to the product from the database and/or to provide supplemental information about the product to the database.
