The performance of contact ic card--xrfid Smart Card

IC card is divided into contact ic card and contactless ic card from the interface, the following we will learn about the performance of contact ic card.

1、Storage capacity

  Magnetic cards can only store a few hundred bytes at most, the magnetic stripe can also be used as a passive storage intermediary. The IC card has internal memory such as RAM, ROM, EEPROM, etc. The storage capacity can be up to megabytes and can store various information such as text, sound, graphics, images, etc. The storage area can be divided and has different access levels.

2. Encryption

  The magnetic card has no control circuit, so its internal data reading and writing cannot be safely controlled, and the reading technology is also sequential and mechanical, while the contact IC card can control the circuit to read and write its internal data, erase control, and read technology is random. The encrypted IC card itself has a security code, if you try to illegally access the data then the card will self-destruct and cannot be read or written again.

3. Dependency on the network

  Magnetic card in use to ensure that the terminal and the host between the very strong real-time, once the host or network failure will paralyze the entire system, while IC card can store a large amount of data, and by the logic circuit control, the use of all operations are completed independently by the terminal, so that its application environment on the computer network in real-time, sensitivity requirements are reduced, very much in line with the current national conditions, conducive to the network quality is not high This is very much in line with the current national conditions and is conducive to the use in environments where the network quality is not high.

4. Service life

    The service life of magnetic cards is short, generally between two months and one year, while the life of IC cards can reach more than ten years without human damage.

5、Interference resistance

   Magnetic cards are poor in terms of anti-magnetic, anti-static and waterproof, and the magnetic stripe cannot be rubbed indiscriminately, while IC cards are stronger in these aspects, but the chip should be kept clean.

6. Anti-counterfeiting

   Magnetic cards are easy to counterfeit, while IC cards themselves have strong logic encryption, making the counterfeit rate more difficult.

7、Convenience

    IC card reading and writing equipment than the magnetic card reading and writing equipment is simple and reliable, the cost is cheap, easy to promote, easy maintenance.

   It is because IC card has many incomparable advantages, so in finance, taxation, public security, transportation, post and telecommunications, communications, services, medical, insurance and other various fields have been widely valued and applied.
