RFID smart cards have penetrated into all aspects of life. For example, our common bus cards, attendance cards, ID cards, membership cards, etc. basically use RFID technology. RFID card readers can read common IC cards, smart cards, ID cards, etc. In addition, they can also read RFID smart cards and RFID tags. A small number of NFC RFID readers can also read NFC cards.
1. IC card
IC card is the general term for smart cards. IC cards have readable and writable memory. The reading and writing of IC card data require corresponding password authentication. The data can be partitioned, and different areas are used for different functions and can have different password protection. The content recorded in the IC card can be repeatedly erased and written, and it is divided into contact and contactless IC cards. RFID is contactless identification, so the card type read is contactless IC card. At present, IC cards are mainly used in subway cards, campus cards, access cards, and ID cards.
2. RFID smart card/tag
RFID readers can also identify corresponding electronic tags or contactless electronic cards. In daily applications, RFID tags are mainly embedded in cards, while in the fields of books and industry, they are more in the form of book tags and electronic tags. Depending on the application, the tag form will also have different changes. As long as the frequency band is consistent and meets the corresponding protocol standards, it can be read and identified by the RFID reader.
3. NFC card
NFC technology evolved from RFID technology. NFC can be understood as a subset of RFID technology, using the 13.56MHz frequency band, while RFID also includes other frequency bands. In addition to the communication protocol, the NFC standard also specifies the data exchange format. The NFC single chip combines the functions of inductive card reader, inductive card and point-to-point, which can identify and exchange data with compatible devices within a short distance.
Therefore, some NFC RFID readers can also read NFC cards. As long as they meet the NFC frequency band and standards, they can read and write NFC card data.
