Description

A card type wireless integrated circuit card

technical field

The invention relates to technical fields such as integrated circuits, wireless radio frequency, electronic circuits, structural design, etc., specifically, a card-type wireless integrated circuit card.

Background technique

IC card (Integrated Circuit Card) is also called Smart card, Intelligent card, Microcircuit card or microchip card. It is made into a card form by embedding a microelectronic chip in a card base conforming to the ISO 7816 standard. The communication mode 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, non-contact IC cards and dual-interface cards (both contact and non-contact communication interfaces).

Due to its inherent advantages such as information security, portability, and relatively complete standardization, IC cards are being used more and more in fields such as identity authentication, banking, telecommunications, public transportation, and parking lot management, such as second-generation ID cards, bank cards, etc. e-wallets for mobile phones, SIM cards for telecom mobile phones, bus cards and subway cards for public transportation, and parking cards for collecting parking fees, etc., all play an important role in people's daily life.

IC card is another information carrier after magnetic card. An IC card refers to an integrated circuit card. The bus card commonly used is a kind of IC card. The common IC card uses radio frequency technology to communicate with the card reader supporting the IC card. There is a difference between an IC card and a magnetic card. The IC card stores information through the integrated circuit in the card, while the magnetic card records information through the magnetic force in the card. The cost of IC card is generally higher than that of magnetic card, but the confidentiality is better.

Non-contact IC card, also known as radio frequency card, has successfully solved the problem of passive (no power supply in the card) and contact-free, which is a major breakthrough in the field of electronic devices. Mainly used in public transportation, telecommunications, banking, 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 belong to the application of security authentication, while bank cards and subway cards use the function of electronic wallets.

The basic working principle of the IC card is: the radio frequency reader sends a set of electromagnetic waves with a fixed frequency to the IC card. There is an LC series resonant circuit in the card, and its frequency is the same as the frequency emitted by the reader. In this way, under the excitation of electromagnetic waves, the LC The resonant circuit resonates, so that there is a charge in the capacitor; at the other end of the capacitor, a unidirectional electronic pump is connected to send 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 working voltage for other circuits, transmit data in the card or receive data from the reader.

With the popularization of smart mobile devices and mobile Internet, traditional contact and non-contact IC cards are limited by special card reading equipment, and their application is becoming more and more inconvenient.
