Die for deforming material in a joining tool, joining tool and method for identifying and/or decetcting the condition of a die

A joining tool system for joining two workpiece materials, the joining tool system comprising:

• a die having a head comprising a top side partially defining a die cavity in which the workpiece materials are to be deformed, a bottom side opposite the top side, a lateral side arranged between the top side and the bottom side, and a stem which extends along a longitudinal axis from the bottom side of the head;
• an identification tag having an antenna for receiving and transmitting signal and a storage for storing information, wherein the antenna is wrapped around the head such that the antenna entirely surrounds the head, and the identification tag acts as part of a die condition sensor;
• a die holder operable for supporting the die such that the die cavity is exposed for receipt of the workpiece materials;
• a setting tool supported by a first arm over the top side of the die;
• and
• a receiver operable to communicate and receive data on a contactless basis from the identification tag, wherein the entire antenna is located between the storage and the top side of the die in a longitudinal direction parallel to the longitudinal axis of the stem.
