Abstract: An identification card apparatus is provided. The identification card apparatus includes a main body formed by a first housing member and a second housing member and an active radio frequency identification module which includes a battery unit having at least one coin cell, an integrated circuit board and a plurality of conductive connecting pieces. One end of the conductive connecting piece connects to a side of the coin cell, and the other end of the conductive connecting piece connects to a surface of the integrated circuit board, thereby forming a bending portion for the conductive connecting piece. Consequently, by improving the structural design of internal elements and their connection relationship, the identification card apparatus can extend the transmission range, reduce the overall dimension in thickness and weight, enhance the connection relationship of the internal elements, and increase vibration resistance, thereby improving convenience of use.
