A, the definition of different:
1, IC card: is a microelectronic chip embedded in the card base in line with the ISO 7816 standard, made in the form of a card.
2, ID card: is a non-writable induction card, with a fixed number, only the use of the "card number" only, in addition to the card number, without any confidentiality function.
3, nfc: the use of NFC technology devices can be close to each other in the case of data exchange, is evolved from the integration of contactless radio frequency identification (RFID) and interoperability technology.
4, RFID card: is for non-contact data communication between the reader and the label, to achieve the purpose of identifying the target.
Two, the application of different:
1, IC card: in the field of identity authentication, banking, telecommunications, public **** transportation, car park management, such as the second generation of ID cards, cell phone SIM cards, bus cards, subway cards, parking fees for parking cards, etc..
2, ID card: attendance, access control 7a64e59b9ee7ad9431333431363038, one card system.
3, nfc: the use of mobile terminals to achieve mobile payment, e-ticketing, access control, mobile identification, anti-counterfeiting and other applications.
4, RFID card: animal chip, car chip immobilizer, access control, parking lot control, production line automation, material management.
Three, different characteristics:
1, IC card: large storage capacity, good security and confidentiality, not easy to be copied, long service life, can be recharged repeatedly, information retention for a long period of time, with anti-magnetic, anti-static, anti-mechanical damage and anti-chemical damage and other capabilities.
2, ID card: data retention time of more than 10 years, the card number can not be changed after writing before sealing the card, absolutely ensure the uniqueness and security of the card number.
3, nfc: used for close-range secure communication, near-field communication transmission range is smaller than RFID.
4, RFID card: rely on electromagnetic waves, does not need to connect the two sides of the physical contact; read and write speed is extremely fast, improve the efficiency of information transmission; each RFID tag is unique; simple structure, high recognition rate, the required reading equipment is simple.
Expanded Information:
One, the difference between NFC and Bluetooth
1, the establishment time is different, NFC communication setup program is simple, the communication setup time is very short, only need 0.1s or so; and the Bluetooth communication setup program is relatively complex, the communication establishment time
2, the transmission distance is different, NFC transmission distance is only 10cm, while the Bluetooth transmission distance can reach 10m, but NFC in the transmission power consumption and security is slightly better than Bluetooth.
3, the transmission speed and operating frequency is different, NFC operating frequency of 13.56MHz, the maximum transmission speed of 424 Kbit/s, while the Bluetooth operating frequency of 2.4GHz, the transmission speed of up to 2.1 Mbit/s.?
Two, contactless IC card and contact IC card compared with the following characteristics:
1, high reliability. As a result of no mechanical contact between reading and writing, to avoid a variety of failures due to contact reading and writing; and contactless IC card surface without exposed chips, no chip off, electrostatic breakdown, bending damage and other worries.
2, easy to operate. Contactless communication so that the reader in the range of 10 cm can be operated on the card, and contactless IC card in the use of non-directional, the card can be swept in any direction across the surface of the reader to complete the operation, not only convenient but also improves the speed.
3, anti-conflict. Contactless IC card has a fast anti-conflict mechanism to prevent data interference between cards, the reader can "simultaneously" handle multiple contactless IC cards.
4, can be adapted to a variety of applications. The characteristics of the contactless Ic card memory structure makes it suitable for a card for multiple uses, according to different applications set different passwords and access conditions.
5, good encryption performance. Contactless IC card serial number is unique, has been solidified before leaving the factory, and there is a two-way authentication mechanism between it and the reader; contactless IC card should be mutually authenticated with the reader 3 times before processing.
