Intelligent card

Abstract

The invention discloses an intelligent card which comprises a master control module, an input and output module, a radio frequency transmitting and receiving module and an input safety module. The input and output module is connected with the master control module and is used for receiving data inputted by users and outputting data to the users, the radio frequency transmitting and receiving module is connected with the master control module and is used for sensing external electromagnetic waves or alternating magnetic fields, data can be exchanged among radio frequency channels by the aid of the radio frequency transmitting and receiving module, energy of the electromagnetic waves or alternating magnetic fields is coupled and is subjected to rectification and voltage stabilization, then power can be supplied to the intelligent card, and the input safety module is used for encrypting and decrypting the data inputted by the users. Owing to the mode, the intelligent card has the advantages that information can be directly exchanged among the users and the intelligent card, and the safety can be improved during information exchange.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a smart card. Background technique [0002] With the development of science and technology, various smart cards (such as bus cards, bank cards, etc.) are widely used in people's daily life. Smart cards bring people a lot of convenience, but the prior art smart cards can only be used as carriers of user information, and cannot interact with users, that is, users cannot display user information to users, and users cannot input data to the smart card. When such an interactive operation is required, the user can only complete it through the card reading terminal, which brings inconvenience to the user. At the same time, when the smart card of the prior art needs to input a password or other private information, it can only be completed at the card reading terminal, and the security of the card reading terminal cannot be guaranteed, so that some private information is easily inte...

Problems solved by technology

Smart cards have brought a lot of convenience to people, but the smart cards in the prior art can only be used as a carrier of user information, and cannot interact with users, that is, they cannot display user information to users, and users cannot input data to smart cards.

When this type of interactive operation is required, the user can only complete it through the card reader terminal, which brings inconvenience to the user

At the same time, because the smart card in the prior art needs to input passwords or other private information, it can only be completed at the card reader terminal, and the security of the card reader terminal cannot be guaranteed, resulting in some private information being easily intercepted or tampered with, causing losses to users.
