What is a smart card used for? What does a smart card mean

Liangang Shengyi smart card is a comprehensive smart card. Provide all financial services available in the market.

If the smart card is not in good contact, turn off the power, pull it out, and re-insert it.

After switching to some paid channels, it is not displayed, so the basic channel cannot be watched, and the device is turned on again.

The smart card is in arrears.

A chip card with a processor, which is divided into a logical encryption card and a CPU card. Mainly used for:

1. Non-contact IC card, such as bus card, ID card, etc.

2. Contact IC cards, such as bank cards.

1.What is a Smart Card? Smart card is a kind of IC card (integrated circuit card), according to the different types of embedded chips, IC cards can be divided into three categories:

1.Memory card: The integrated circuit in the card is a programmable read-only memory EEPROM that can be erased with electricity, which only has data storage function and has no data processing capability; The memory card itself has no hardware encryption function, only encrypts the files, which can be easily cracked.

2.Logic encryption card: The integrated circuit in the card includes an encryption logic circuit and a programmable read-only memory EEPROM, which can protect the security of the card and the data in the card to a certain extent, but it is only a low-level protection and cannot prevent malicious attacks.

3.Smart card (CPU card).

Shenzhen Huixin card.

Smart cards are divided into three categories, proximity cards, contact cards, dual-interface cards, ......

Smart Card Advantages:

1. Easy to carry: the light card can be easily put in the wallet or card bag, and can be mailed.

2. Large storage capacity of potato hall: one card can store 4-6 megabytes of information. Other portable information media (magnetic cards, IC cards.

microfiche) cannot be compared.

3. High reliability and high security of information recording: Because it is a laser punching recording method, the card is not afraid of any electromagnetic interference, and has a strong ability to resist water, pollution and drastic temperature changes. Anyone who tries to change the content of the information in the card by any means must leave a trace.

4. High confidentiality: Canon optical card has a unique design of optical card information confidentiality measures, which can achieve one card and one code, which cannot be read by conventional methods, let alone deciphered.

5. Relatively cheap.

Smart Card Cons:

Another disadvantage of smart cards is that not all smart card readers.

All are compatible with all types of smart cards. There are many types of smart cards, some of which use non-standard protocols for data storage and card interfaces; Some smart cards and card readers also use proprietary software that is not compatible with other card readers.

Although smart cards are useful for many applications.

may be safer, but they are still vulnerable to certain types of attacks. An attack that can recover information from a chip through smart card technology. Difference.

Power analysis can be used to infer on-chip private keys used by public-key algorithms such as RSA. Some implementations of symmetric cryptography are also susceptible to timing attacks or differential power analysis. The smart card can also be physically dismantled to access the on-board microchip.
