Embodiment 1

[0056] Embodiment 1 of the present invention first discloses a method for accessing sector data of a smart card applied to a first device, the first device is a device-end processing device of a terminal device with a smart card, that is, the method is applied to the device-side of the terminal device , taking terminal devices such as mobile phones as an example, the smart card may be a SIM card of a mobile phone, and the first device may be a mobile phone APP (Application, application program) installed on a mobile phone, refer to figure 1 Shown is a flowchart of a method for accessing smart card sector data, the method may include the following steps:

[0057] Step 101. When a modification request for the data of the first sector of the smart card is received, a modification interface is displayed; the modification request is a request triggered by the user after obtaining the data modification authority of the first sector.

[0058] In one embodiment of the present inventio...

Embodiment 2

[0085] Embodiment 2 of the present invention continues to supplement the method for accessing smart card sector data applied to the first device in Embodiment 1. Refer to image 3 , the method may also include:

[0086] Step 104. When receiving a query request for the first sector data of the smart card, send a data acquisition instruction to the second device; the data acquisition instruction is used to instruct acquisition of the first sector data of the smart card;

[0087] Step 105. Receive the first sector data of the smart card fed back by the second device, and display the first sector data.

[0088] When the user needs to check the data of the first sector of the smart card of the terminal device, for example, to check the balance of the bus card, etc., the first device can be triggered by performing a corresponding trigger operation on the first device of the terminal device Call up the viewing function of the first sector data, such as clicking the view button on th...

Embodiment 3

[0097] Embodiment 3 discloses a system for accessing sector data of a smart card, refer to Figure 5 A schematic structural diagram of a system for accessing sector data of a smart card is shown, the system includes a first device 51 and a second device 52 .

[0098] Wherein, the first device is specifically a device-side processing device of a terminal device with a smart card, refer to Figure 6 The schematic structural diagram of the first device shown, the first device includes: a first display unit 61, configured to display a modification interface when receiving a modification request for the first sector data of the smart card; the modification The request is a request triggered by the user after obtaining the data modification authority of the first sector; the first receiving unit 62 is configured to receive the new first sector data input by the user on the modification interface, and transfer the The new first sector data is updated to a predetermined cache file; w...

Abstract

The invention discloses a method and a system for having access to sector data of a smart card, a first device and a second device. The method comprises the steps that when a modification request for first sector data of the smart card of terminal equipment is received, a first modification interface is displayed; the modification request is triggered after a user obtains a modification permission for the first sector data; new first sector data input by the user is received and updated into a predetermined cache file, wherein the cache file pre-stores backup data of the first sector data; a data modification command is sent to the second device so that the second device can update the updated data in the cache file into a first sector, wherein the second device is a card processing device for the smart card of the terminal equipment. It shows that by the application of the scheme, the user can have access to the data in an M1 sector (namely the first sector) of the smart card of the terminal equipment in a contact mode in the terminal equipment, and therefore the demand of the user for contact access in the using process of an M1 application on the terminal equipment is met.

Description

technical field [0001] The invention belongs to the technical field of smart cards, in particular to a method and a system for accessing sector data of a smart card. Background technique [0002] Mifare is one of the trademarks owned by NXP Semiconductors. With the sales of more than 5 billion smart cards and IC (Integrated Circuit) cards and more than 50 million card readers, Mifare has become the world's most The technology of choice for contactless smart cards and the most successful platform in the field of automated fare collection. [0003] At present, Mifare applications, such as M1 (Mifare one) applications are mainly used on various types of cards such as bus cards, access control cards, campus cards, and meal cards. Data interaction between devices, such as recharging bus cards / meal cards through card readers, or swiping cards for consumption, etc. [0004] With the popularity of NFC (Near Field Communication, near field communication) mobile phones and the wides...
