Something About Smart Cards

No matter how different the appearance, regardless of the appearance, the application field has its own merits. At its core, it is decided that it can become only one of the smart cards, that is, the microchip inside the card. Among them, it is divided into contact type and non-contact type according to different chip protocols. Contact chips follow the ISO7816 protocol and Contact-Less IC Card follow the ISO14443 protocol. The so-called contact type, such as a bank card, you need to insert the bank card into the machine before you can use it, instead of contact type, such as ID card, transportation card, you only need to put the card into the sensing area to complete the data reading and transmission.
