1. A method for identifying and/or detecting a condition of a die for deforming material in a joining tool, the method comprising the steps of:
providing the joining tool including the die, the die including a head and a stem, the head having a top side defining a surface for deforming the material, a bottom side opposite the top side, a lateral side arranged between the top side and the bottom side, the stem extending along a longitudinal axis from the bottom side of the head;
providing an identification tag including an antenna for receiving and/or transmitting a signal, and a storage for storing information, wherein the antenna is wrapped circumferentially around the head such that the antenna entirely surrounds the head;
providing a receiver which communicates and receives data on a contactless basis from the identification tag;
establishing a communication between the identification tag arranged on the die and the receiver; and
detecting a communication change between the identification tag and the receiver in order to detect a change in the condition of the die, wherein the entire antenna is positioned between the storage and the top side of the head in a direction parallel to the longitudinal axis of the stem.
