There are two main differences between the landlord's credit card chip card and magnetic stripe card. First of all, the chip card has a large capacity, works like a microcomputer, and can have multiple functions at the same time. Chip cards are divided into pure chip cards and magnetic stripe chip composite cards, which have become the development trend of global bank cards because of their high security and multi-functional applications. Secondly, a magnetic card is a kind of magnetic recording medium similar to a card, which uses a magnetic carrier to record characters and digital information for identification or other purposes. The magnetic card is made of high-strength and high-temperature resistant plastic or paper-coated plastic, which is moisture-proof, wear-resistant, flexible, convenient to carry and stable and reliable to use. At present, most bank credit cards are chip cards.
