What is IC and its advantages?
Broadly speaking, IC is the general term for semiconductor component Sourcing products, including:
1. Integrated circuit (integrated circuit, abbreviation: IC)
2. Two, triode.Electronic Resistor and Capacitor，and Electronic connectors
3.Special electronic components.
More broadly speaking, it also involves all electronic components, such as resistors, capacitors, circuit boards/PCB boards,Turkey PCB Assembly and many related products.
Compared with magnetic cards, IC cards have the following advantages.
Reliable. The IC card reads and writes information by contacting the contact head of the reading and writing device with the contact point of the integrated circuit on the card. There are no moving parts, and there will be no card eating or jamming. In addition, the IC card has strong anti-interference ability and has anti-magnetic and anti-static functions.
Safety. All the information of the IC card that needs to be kept secret and the programs used for security control are set in a non-copyable storage area that prevents outside intrusion, thereby ensuring the security and confidentiality of the information. During the production process, a corresponding password is set up inside the card, which can effectively prevent counterfeiting. In addition to verifying the cardholder's password (referred to as PIN) to ensure safe use, biometric authentication technology can also be used to further increase security. For example, the validity of the card can be verified by recognizing the fingerprint, handwriting, voice, etc. of the cardholder.
Large storage capacity. The storage capacity of an IC card is generally more than 1000 times that of a magnetic card. Usually can store 3000 bytes, and now scientists are planning to increase it three times. Therefore, it can store a large amount of various kinds of information, and it can achieve multiple functions with one card.
Flexible. The IC smart card can carry out logical operations, so it can carry out safety authentication and operation authority authentication without being connected to a central computer. In addition, users can request to modify the personal data stored in the IC card, check the remaining amount, etc.
