Juxian one-card processing procedure
All-in-one card is a common name for smart cards, and the following smart cards are called all-in-one cards:
National Urban One-Card Interconnection: It is a domestic general electronic ticket issued by the Ministry of Housing and Urban-Rural Development of China, which is mainly used for small payment of urban public transportation.
National Traffic Card Interconnection: It is a domestic general electronic ticket issued by the Ministry of Transport of China, which is mainly used for small payment of urban public transportation.
Extended data:
Smartcard (English: smart card or ICCard), also known as smart card, smart card, integrated circuit card and IC card, refers to a kind of portable card plastic stuck or embedded in integrated circuit chip. The card includes microprocessor, I/O interface and memory, and provides data operation, access control and storage functions. At present, the card size and contact definition are unified by ISO specification, mainly in ISO78 10. Common ones are telephone IC cards, identity IC cards, and some transportation cards and memory cards.
history
Smart card is an integrated circuit chip card with the same appearance as a credit card. It is also called "integrated circuit card" and smart card. The English name is "integrated circuit card" or "smart card". It was invented by Frenchman Roland Moreno in 1974. The integrated circuit chip module with storage, encryption and data processing capabilities is packaged in a plastic substrate with the same size as the formed credit card. French Bohr Computer Company made IC card products for the first time in 1976, and began to apply them in various fields.
form
Substrate: ABS, PVC, PET, PC. Now most of them are made of PVC, but also plastic or paper.
Contact surface: metal material, usually copper, and the input and output terminals of the integrated circuit are linked into a large contact surface, which is convenient for the operation of the card reader and also helps to prolong the service life of the card; Generally, there are 8 contacts (C 1C2C3C4 C5C6 C7, C4 and C8 are designed to be reserved for the future), but due to historical reasons, some smart cards are designed with 6 contacts (C 1C2C3C5C6C7). In addition, C6 was originally designed to supply power to EEPROM, but later, the programming voltage required by EEPROM was directly controlled by the chip, so C6 is usually no longer used.
Integrated chip: usually very thin, less than 0.5mm, with a diameter of about 1/4 cm, generally round or square. Internal chips generally include CPU, RAM, ROM and EPROM.
