Inductive IC cards are composed of IC chips and inductive antennas, encapsulated in a standard PVC card, with no exposed parts of the chip and antenna. The types we commonly see include domestic F08, S50, S70, IISI, 4439, Kunrui, and inductive CPU cards, among which domestic F08, S50, and S70 are frequently used. The standard size of IC cards is 85.5540.84MM, which is exactly the same as the bank stored-value cards and credit cards issued nowadays. They can complete data reading and writing operations through the transmission of radio waves when they are close to the surface of the reader-writer within a certain distance range (usually 5-10mm).

Currently, the application of inductive IC cards is quite extensive, involving various aspects such as telecommunications, finance, post, transportation, commerce, healthcare, education, public transportation, campus one-card-for-all, hospital medical care, access control, and security. They have become an indispensable part of our lives.
