Smart card and smart card operation method

Abstract

The intelligent card provided by the invention comprises a chip, a power supply unit for supplying power to the chip and a switch unit; AND the switch unit is used for enabling the chip to run or stoprunning according to input operation sent by a user. According to the smart card provided by the invention, the chip can run or stop running only after the user sends the input operation. Therefore,according to the intelligent card provided by the invention, the problems of unexpected card swiping, unauthorized card swiping and the like under the condition that a user is not informed are avoided, and meanwhile, only the switch unit is additionally arranged in the intelligent card, so that the cost of the switch unit is relatively low, the cost control is facilitated, and large-scale production is easy to realize.

Description

technical field [0001] The invention belongs to the control field of smart cards, and in particular relates to a smart card and a smart card operation method. Background technique [0002] At present, contactless smart cards are widely used in finance, transportation and other fields. They are convenient and quick to use. You only need to wave the card in a specific area of ​​the terminal to complete the transaction without physical contact. But at the same time, the convenience of contactless smart cards will also be exploited by criminals. Since the contactless smart card has the characteristics that the transaction does not require physical contact, criminals can use the handheld terminal device to communicate with the smart card in the user's clothing or package without the user's knowledge, obtain user information, and even complete consumption. transactions, causing economic losses to users. [0003] In order to prevent problems such as accidental card swiping and fr...

Problems solved by technology

Since the contactless smart card has the characteristics that the transaction does not require physical contact, criminals can use the handheld terminal device to communicate with the smart card in the user's clothing or package without the user's knowledge, obtain user information, and even complete consumption. transactions, causing economic losses to users

[0003] In order to prevent problems such as accidental card swiping and fraudulent swiping, a magnetic shield card sleeve is provided in the prior art, and the smart card is put into the magnetic shield card sleeve as a remedy. However, this method requires users to change their usage habits. It is not convenient for users to use, if you forget to put it in, it will still cause losses

The prior art also provides a non-contact smart card with a fingerprint module, which solves the problem of accidental card swiping while improving the security of the smart card. However, adding a fingerprint module usually requires adding a thin-film battery as a fingerprint module. power supply, and need to increase related supporting circuits, which greatly increases the manufacturing cost of smart cards
