A method for transmitting product information read from an identification tag to another processor and a system therefore. The system finds one application in radio frequency (RFID) tags. The method includes receiving data read from a tag by a tag reader, the data including product data identifying the product to which the tag is attached and tag data uniquely identifying the tag and forwarding the product data but not the tag data to another processor. This ensures that the part of the tag number which specifically identifies the particular product is kept private.
