1. The ic card and uid card have the following differences
UID card is a kind of IC card, this card can modify any sector, as a sub-card of M1 replication, mainly used in IC card replication.
2. ID card refers to a read-only card containing EM chip or other chips, with a frequency of 125KHZ. Widely used. He can only read the serial number, he can't write in it. The ID card reader is now the most circulating card reader on the market, with a variety of transmission formats, and almost all can be used.
3, and HID card is a card reader and card brand in the United States, it is just a product brand, and the ID actually does not have much to do with it, but it is also a kind of ID card, but its factory chip according to the region have set a serial number, added secret, so it has a custom format, can not be used with other brands of card readers. That is, HID cards can only be used on HID card readers.
The main body is different, ic card is the microchip embedded in the ISO7816 standard card base, ID card is not written induction card.
The characteristics are different, ic card has a small size and easy to carry, large storage capacity, high reliability, long service life, strong confidentiality and high security characteristics, ID card in addition to the card number without any security function.
Different applications, ic cards are used in finance, transportation, medical, identification and other industries, and ID cards are used as identification.
IC cards and UID cards are small chips that can store data, and they both have a high degree of security and reliability.
IC card is the abbreviation of integrated circuit card, also known as smart card, crystal card or multi-function card. It achieves confidential transmission by storing data on a microprocessor. It can be read and written by a reader and, when used, produces a RANDOM NUMBER to encrypt the transmitted data.
UID card is short for contactless reader, also known as RFID tag or radio frequency tag. It does not contain a microprocessor, but stores all the information in a small integrated circuit. When excited by a contactless reader, the information stored inside can be transmitted externally.
IC card, 0 sector can not be modified, other sectors can be repeatedly erased, we use the elevator card, access card and other smart card issuers are used M1 card, which can be understood as the original card issued by the property.
< br >
UID card ordinary copy card, can repeatedly erase all sectors, mainly used in IC card copy, encountered with a firewall card reader will fail.
The main difference between ic card and id card is the following three aspects:
< br >
1. On the main body, the ic has memory and can read and write, while the id card is an induction card that cannot be written and has a fixed number;
< br >
2 features, ic card small size, easy to carry, high reliability, id card is open, can not be kept secret;
< br >
3. In application, ic cards are often used in financial, medical and other industries, while id cards are generally used as user identification of access control systems.
1 ic card and uid card is different
2 ic card is an integrated circuit card, internal storage chip, can be encrypted and decrypted and other operations, often used in bank cards, access control cards and other fields; uid card is a passive radio frequency card, internal storage has a fixed unique identification code, can be contactless identification, often used in public transport cards, access cards and other fields.
3 Although both cards can be used in areas such as access control cards, their technical principles and application fields are different, and the appropriate card needs to be selected according to the specific situation.
The differences between ic cards and uid cards are as follows
IC card full name integrated circuit card, also known as smart card. Read and write, large capacity, encryption function, data record safe and reliable, more convenient to use, belongs to high frequency, frequency is 135MHz, mainly used for card system, consumer system and so on.
UID card is a kind of IC card UID card can be modified any sector, as a sub-card of M1 replication, mainly used in IC card replication. The card is fully compatible with mifare 1k cards. The block0 of the card (the block where the UID resides) can be modified arbitrarily and repeatedly.
