Abstract
An electronic device includes first and second antennas, a magnetic stripe transmission (MST) integrated circuit (IC), and a processor. The first antenna is disposed between first and second surfaces of the electronic device and in parallel with the first and second surfaces of the electronic device. The first antenna outputs a signal in a first direction. The second antenna is disposed between the second surface of the electronic device and the first antenna and in parallel with the first and second surfaces of the electronic device. The second antenna outputs a signal in a second direction. The MST IC controls the first and second antennas. When a payment mode is executed, the processor controls the MST IC such that one of the first and second antennas outputs an MST signal and the other of the first and second antenna outputs a jamming signal for interfering with wiretapping of the MST signal.
