Embodiment 1

[0056] This embodiment provides a visual card, such as figure 1As shown, the video card includes: a main control module 11 , an antenna module 12 , a power management module 13 , a display module 14 and a signal conversion module 15 . The main control module 11 is connected to the antenna module 12, the power management module 13, the display module 14 and the signal conversion module 15; the antenna module 12 is also connected to the signal conversion module 15;

[0057] The main control module 11 is used to communicate with the external card reader through the antenna module 12, update and store key information; it is also used to monitor the departure signal according to the electrical signal input by the signal conversion module 15; Obtain key information when receiving a signal, and control the display module 14 to display the key information.

[0058] The antenna module 12 is used to realize the communication between the main control module 11 and the external card read...

Embodiment 2

[0088] This embodiment provides a working method of a video card, see Figure 15 , including:

[0089] Step 101, the visual card is initialized, and a connection is established with an external card reading device;

[0090] The video card initialization specifically includes initializing the attributes of each chip pin as input or output attributes, and setting the system operating clock.

[0091] Step 102, the visual card judges whether a departure signal is received, if so, execute step 104; otherwise, execute step 103 when the visual card receives an operation instruction;

[0092] Specifically, step 102 is specifically to monitor and detect whether the level of the IO is a low level by the video card, and if so, determine that the video card has monitored the departure signal; otherwise, determine that the video card has not monitored the departure signal.

[0093] Furthermore, in this embodiment, the visual card monitors whether the level of the P00 pin is low, and if s...

Abstract

The invention relates to the field of communication and in particular to a visual card and an operating method thereof. The visual card comprises a master control module, an antenna module, a power management module, a display module and a signal conversion module. The master control module is connected with the antenna module, the power management module, the display module and the signal conversion module. The signal conversion module is also connected with the antenna module. The master control module is used for communicating with an external card-reading device through the antenna module, updating and storing key information, monitoring an off-field signal according to an electric signal input by the signal conversion module, acquiring the key information when monitoring the off-field signal, and instructing the display module to display the key information. The signal conversion module is used for converting the electric signal generated by the antenna module and transmitting the converted signal to the master control signal. The power management module is used for powering the master control module. The visual card can process and display data, and continuously display content after being swiped.

Description

technical field [0001] The invention relates to the communication field, in particular to a video card and its working method. Background technique [0002] IC card, also known as integrated circuit card, is widely used in finance, telecommunications, transportation, security management and identification due to its portability and large storage capacity. In the existing technology, the IC card has a large capacity and can store consumption details and user information. After adding display technologies such as electronic paper, the content can be displayed. The displayed content can be key information such as electronic cash balance, transaction details, and custom data of the card issuer. . [0003] However, only when the IC card is in the magnetic field can the power display content be obtained, that is, the content can be displayed only when the card is swiped, and the content cannot be displayed when the IC card leaves the magnetic field, which causes great inconvenien...
