A cartridge assembly for breaching a door including a cartridge case, a cartridge body, and a fuse. In the casing, the circuit board is joined to the casing and the transformer unit is fixed to the circuit board through a heat conductive member having thermal conductivity of more than 0. By separating the two stabilization methods, unfavorable interactions between them is reduced. Thus, the changes in the length of the magnetostriction oscillator due to the magnetic excitation of the excitation coil appearing at the first and second end surfaces is directly supported by the first and second support surfaces. In some arrangements, the system and methods pertain to receiving data to be included in a check to be printed via a network, configuring the received data for printing on a check, and facilitating printing of the check.
