Secure anti-skimmer technology for use with magnetic cards

Detecting and reporting skimming of a magnetic stripe of a magnetic instrument having a magnetic stripe. The magnetic head detector detects a reading of the magnetic stripe from the magnetic instrument and, if the reading is detected, transmits a reporting signal to a microchip indicating the magnetic stripe was read. The microchip receives the reporting signal from the magnetic head detector and transmits a buzzer signal to a microbuzzer. The microbuzzer generates an audible notification when the buzzer signal is received from the microchip. A microbattery powers the magnetic head detector, the microchip, and the microbuzzer.
