Embodiment 1

[0042] Please refer to figure 1 , is a schematic structural diagram of the contactless radio frequency card in this embodiment. The non-contact radio frequency card in this embodiment includes: a main control module, a radio frequency transceiver module, and a sensing unit; the sensing unit is used to collect motion information of the non-contact radio frequency card and generate corresponding data for transmission to the A main control module, the main control module is used to judge whether to start the radio frequency transceiver module according to the data transmitted by the sensing unit, and the radio frequency transceiver module is used for radio frequency data interaction with the outside world.

[0043] The action of the user when swiping the card is to first speed up and take out the radio frequency card to make the radio frequency card close to the card reader, and then slow down so that the card is facing the card reader. The sensing unit in the radio frequency ca...

Embodiment 2

[0049] Such as Figure 6 Shown is the frame flow chart of the working method of the non-contact radio frequency card in this embodiment. The working method of this implementation non-contact radio frequency card comprises the steps:

[0050] The sensor unit collects the motion information of the non-contact radio frequency card, and generates corresponding data and transmits it to the main control module;

[0051] The main control module judges whether the contactless radio frequency card is in a card swiping movement according to the data transmitted by the sensing unit;

[0052] When the main control module judges that the non-contact radio frequency card is swiping the card, it turns on the radio frequency transceiver module in the radio frequency card to exchange radio frequency data with the outside world.

[0053] The above-mentioned sensor unit collects the motion information of the non-contact radio frequency card, and generates corresponding data for transmission to...

Abstract

The invention discloses a non-contact type radio frequency card and a working method of the non-contact type radio frequency card. The non-contact type radio frequency card comprises a main control module, a radio frequency receiving and dispatching module and a sensing module. The sensing module is used for collecting motion information of the non-contact type radio frequency card, generating corresponding data and transmitting the corresponding data to the main control module. The main control module is used for judging whether the radio frequency receiving and dispatching module is needed to be started according to the data transmitted by the sensing module. The radio frequency receiving and dispatching module is used for conducting radio frequency data interaction with the outside. The non-contact type radio frequency card can effectively solve the security problem that the non-contact type radio frequency card is swiped fraudulently when an effective card swiping distance of a card reader is changed maliciously.

Description

technical field [0001] The invention relates to the field of radio frequency technology, in particular to a non-contact radio frequency card and a working method thereof. Background technique [0002] With the development of intelligent technology, non-contact IC cards with radio frequency functions have been widely used in daily life, such as bus card, campus card and so on. Non-contact IC card, also known as induction card and radio frequency card, is a new technology developed in recent years. It successfully combines wireless identification technology and IC card technology to solve the problem of passive (no power supply in the card) It is a major breakthrough in the field of electronic devices to solve the difficult problem of contactless and non-contact. Compared with the traditional contact IC card, it inherits the advantages of the contact IC card, such as large capacity and good confidentiality, and overcomes many weaknesses of the contact IC card, such as high me...
