• How Does A Magnetic Stripe Reader Work?

---

The working principle of magnetic card is actually the mutual conversion of magnetism, electricity and light.

When swiping the magnetic swipe card, move the side with the magnetic stripe to the side with the reading head in the slot of the card reader (generally curved roller-shaped) quickly.

The induced current generated by the energized conductor in the magnetic field is related to the size of the magnetic field so that the information of the magnetic card can be converted into a current signal.

The current signal can be converted into various information and displayed on the fluorescent screen by the CPU in the computer.
