A multilayer tubular structure for products with an identification device being embedded or interposed between two of the multiple layers of the tubular structure. The identification device is responsive to radio frequencies and is able to store and transmit information about the multilayer tubular structure, the products, and processes that have been performed on same. A method is provided for manufacturing a multilayer tubular structure by embedding a radio frequency identification device between two of the multiple layers.
