Relationship between various concepts of ID card, IC card, RFID card, NFC card, Mifare card
The difference between IC card and ID card
The ID card only records the card number, and there is no authority to read the card number in the card, so it is easy to imitate. The ID card cannot write data, and its recorded content (card number) can only be written by the chip manufacturer at one time, and the developer can only read the card number for further processing. It is impossible to formulate a new number management system according to the actual needs of the system.
The reading and writing of data recorded in the IC card requires corresponding password authentication, and even each area in the card has different password protection to fully protect data security. The password for writing data in the IC card and the password for reading data can be set For different reasons, it provides a good hierarchical management method to ensure system security. IC cards can not only read a large amount of data by authorized users, but also allow authorized users to write large amounts of data (such as new card numbers, user permissions, user information, etc.), IC cards The content recorded in the card can be repeatedly erased and written. The security of the IC card is much greater than that of the ID card.

The difference between IC card and RFID card
IC cards are divided into contact and non-contact IC cards, both of which belong to the RFID category. The chip of the contact IC card is directly packaged on the surface of the card base, while the non-contact IC card is composed of a chip and a coil, which can be divided into COB copper wire , etched antenna, printed antenna, etc. The difference between the two applications is that the former needs to be inserted into the card reader during use, such as a bank card, and the latter can be read only by being close to the card reader induction antenna, such as traffic card, access control card.
RFID cards refer to non-contact electronic cards/labels, including ID cards, IC cards, NFC cards and other electronic cards/labels. The main difference between them is the working frequency band.
The ID card is an early non-contact electronic tag. It has only one ID number in the working frequency band of 125kHz and cannot store any data, so it is called an ID card.
IC card, as understood from the meaning of the word, includes other RFID electronic tags and contact chip cards except ID cards, but generally speaking, IC cards mainly refer to non-contact smart cards and contact smart cards that work in the 13.56MHz frequency band. Non-contact smart cards also include NFC cards or tags (NFC Forum stipulates that there are four types of cards that belong to NFC cards), and contact smart cards are smart cards with a bare chip.
RFID cards also include electronic cards/tags in other working frequency bands, such as 915MHz, 2.4GHz and other frequency bands.
