Are the magnetic cards used in the bus card?

Answer:

When approaching the card machine, the coil generates an induced voltage to transfer data from the card to the external database.
It's an induction type, unlike a bank card, a magnetic material with thin copper wires around it, and a small chip attached to it. The chips are responsible for storing personal information,
Bus card is a contactless card data, it is through the integration in the card chip on the card function through the induction coil (coil inductance coil is made of copper wire coiled coil ends) through various circuit to make the role of induction current into DC, DC from both ends into a relatively large the voltage across the capacitor, can remain stable, the coil ends and then leads to the two line to the chip, as the signal transmission line.
