1, magnetic card: similar to the bank card, the reverse side has a black magnetic stripe. Generally suitable for single-store use. The reverse magnetic strip only stores the number without any other thing, because the uniqueness of the magnetic card number ensures that different users have different card numbers. When using a magnetic card for membership management, the amount of membership savings, points, or discounts is achieved through software. The characteristics of this kind of card: cheap, ordinary. Disadvantages: Magnetism is easily lost near strong magnetic fields.
2, ID card: similar to the large company open the door card. ID cards are contactless cards. The card itself has coils, and only the number of the card is read out by the reader and other related devices. The ID card itself does not store other things.

Features: The price is moderate, because it is the induction card reader does not affect the wear of the card and the machine.
3, IC card: Contact-type IC card is similar to a telephone card; non-contact IC card is also called M1 card similar to Shanghai bus card. Contact IC card Because the chip is exposed on the outside, the card itself often comes in contact with the machine and it easily causes wear. Since the contactless IC card is not in contact with the machine itself due to the fact that it is an inductive reader, the maintainability is relatively high. The IC card itself has a chip that divides different similar types of cards according to the capacity of the chip. Generally, there are more 4442 IC cards on the market.
