Embodiment 1

[0033] Embodiment 1 of the present invention provides a control method for a non-contact smart card. The method is applicable to non-contact smart cards such as financial cards and bus cards that adopt non-contact communication technology. The embodiment of the present invention does not make any limited. Such as figure 1 As shown, it is a schematic flow chart of the control method described in Embodiment 1 of the present invention, and the method may include the following steps:

[0034] Step 101: The smart card control client receives a first instruction; the first instruction is used to instruct the smart card control client to disable the contactless communication capability of the contactless smart card connected to it for communication.

[0035] Specifically, the smart card control client can usually be client software installed in the terminal device, such as a smart card control APP (Application, application program) developed according to needs. At this time, because...

Embodiment 2

[0052] In the second embodiment of the present invention, taking the executor as an example of a contactless smart card, the control method of the contactless smart card in the first embodiment of the present invention is further described, as follows figure 2 As shown, it is a schematic flow chart of the control method described in Embodiment 2 of the present invention, and the method may include the following steps:

[0053] Step 201: The contactless smart card receives a prohibition instruction sent by the smart card control client connected to it in communication; the prohibition instruction is sent by the smart card control client to the contactless smart card when receiving the first instruction; The first instruction is used to instruct the smart card control client to disable the contactless communication capability of the contactless smart card connected to it for communication.

[0054] Specifically, the non-contact smart card may be a non-contact smart card such as...

Embodiment 3

[0073] The third embodiment of the present invention takes the smart card control client and the interactive execution of the contactless smart card as an example to further explain the control method of the contactless smart card described in the first or second embodiment of the present invention, as follows image 3As shown, it is a schematic flow chart of the control method of the contactless smart card described in the third embodiment of the present invention, and the method may include the following steps:

[0074] Step 301: When the smart card control client receives the first instruction, it sends a prohibition instruction to the contactless smart card connected to it; the first instruction is used to instruct the smart card control client to close the contactless smart card connected to it. The contactless communication capability of smart cards.

[0075] Specifically, the smart card control client may first establish a communication connection with the contactless s...

Abstract

The invention discloses a control method, equipment and a system of a non-contact intelligent card. The method includes: when an intelligent card control client sends an inhibition instruction to the non-contact intelligent card connected with the intelligent card control client in a communication manner when receiving a first instruction, the non-contact intelligent card is indicated to close a channel having access to an upper application program from a non-contact interface according to the inhibition instruction, and the first instruction is used for indicating the intelligent card control client to turn off the non-contact communication capability of the non-contact intelligent card connected with the intelligent card control client in a communication manner. According to the scheme, the inhibition instruction is sent to the non-contact intelligent card via the intelligent card control client, the non-contact intelligent card is indicated to close the channel having access to the upper application program of the non-contact intelligent card from the non-contact interface, the control cost of the non-contact intelligent card can be reduced, the problem that unencrypted information in the non-contact intelligent card is easily stolen is solved, and the effect of improving the information security of the non-contact intelligent card is achieved.

Description

technical field [0001] The invention relates to the technical field of smart cards, in particular to a control method, device and system for a non-contact smart card. Background technique [0002] Non-contact smart cards such as financial cards and bus cards using non-contact communication technology have near-field communication capabilities, which bring great convenience to users for financial payment and other operations. Specifically, when using the contactless smart card, the user only needs to lightly touch the corresponding contactless terminal to complete the corresponding payment process. [0003] However, it is precisely because of this that the unencrypted information of such contactless smart cards, such as card numbers, ID numbers, electronic cash balances, and consumption records, are easily leaked. For example, use terminals that use the same contactless communication technology as contactless smart cards, such as POS (Point of Sale, sales terminal) machines,...
