ABSTRACT:
A method of maintaining a status of a product item is provided. The product item includes an associated interface surface which has coded data including a plurality of coded data portions indicative of the product item's identity. The method includes, in a sensing device, sensing at least one coded data portion, generating indicating data indicative of the product item identity therefrom, and transferring the indicating data to a computer system. The computer system is responsive to the indicating data to update product status information stored in a data store. The coded data is substantially invisible to the unaided eye.
