Description

A card-type wireless integrated circuit card

Technical field

The invention relates to the technical fields of integrated circuits, wireless radio frequency, electronic circuits, structural design, etc. Specifically, it is a card-type wireless integrated circuit card.

Background technique

IC card (Integrated Circuit Card), also known as smart card, intelligent card, microcircuit card or microchip card, etc. It embeds a microelectronic chip into a card base that complies with the ISO 7816 standard and makes it into a card form. The communication method between the IC card and the reader can be contact or non-contact. According to the communication interface, IC cards are divided into contact IC cards, contactless IC cards and dual-interface cards (with both contact and contactless communication interfaces).

Due to its inherent information security, portability, relatively complete standardization and other advantages, IC cards are increasingly used in fields such as identity authentication, banking, telecommunications, public transportation, parking lot management, etc., such as second-generation ID cards, banks Electronic wallets, mobile phone SIM cards from China Telecom, bus cards and subway cards for public transportation, parking cards used to collect parking fees, etc. all play an important role in people's daily lives.

IC card is another information carrier that appears after magnetic card. IC card refers to an integrated circuit card. The commonly used bus card is a type of IC card. Common IC cards use radio frequency technology to communicate with card readers that support IC cards. There is a difference between IC cards and magnetic cards. IC cards store information through the integrated circuit in the card, while magnetic cards record information through the magnetism in the card. The cost of IC cards is generally higher than that of magnetic cards, but their confidentiality is better.

Contactless IC cards, also known as radio frequency cards, successfully solve the problem of being passive (no power supply in the card) and contact-free, and are a major breakthrough in the field of electronic devices. Mainly used in public transportation, telecommunications, banks, parking lot management and other fields. The main functions include security authentication, electronic wallet, data storage, etc. Commonly used access control cards and second-generation ID cards are security authentication applications, while bank cards, subway cards, etc. use the electronic wallet function.

The basic principle of IC card work is: the radio frequency reader and writer sends a set of fixed frequency electromagnetic waves to the IC card. There is an LC series resonant circuit in the card, whose frequency is the same as the frequency emitted by the reader and writer. In this way, under the excitation of electromagnetic waves, the LC The resonant circuit resonates, so that there is charge in the capacitor; at the other end of the capacitor, there is a one-way electron pump, which sends the charge in the capacitor to another capacitor for storage. When the accumulated charge reaches 2V , this capacitor can be used as a power supply to provide operating voltage for other circuits, transmit data in the card or receive data from the reader/writer.

With the popularity of smart mobile devices and mobile Internet, traditional contact and non-contact IC cards are subject to the limitations of dedicated card reading equipment, making their application increasingly inconvenient.
