Description

A card that communicates with smart devices via a capacitive touch screen

technical field

The invention relates to a card, in particular to a card for communicating with an intelligent device through a capacitive touch screen.

Background technique

Currently, wireless one-way or two-way communication between smart devices (mobile devices such as cell phones with capacitive touch screens) and other devices without the use of radios, voices, cameras or direct connections is difficult. This makes devices such as smart credit cards need to communicate with smart mobile devices in a cumbersome way of sending passwords or other information.

For example: the methods currently used include Bluetooth, WIFI, NFC, contactless smart cards or built-in cameras to take pictures, while the wireless methods such as Bluetooth and WIFI have power consumption problems, and if smart credit cards are connected to smart devices through Bluetooth and WIFI , due to the limited battery capacity of the smart credit card itself, it can only last for a week, and the signals of Bluetooth and WIFI are easily intercepted, and there is also a risk of information leakage and theft. The installation range of NFC and contactless smart cards is relatively limited, for example, this function is not available on Apple mobile phones.

At present, there is also a smart credit card that can generate a password on the card display screen, but the user still needs to manually input this string of passwords into the smart device or cash register, and the password generated by such a smart credit card will be updated within about 30 seconds At the same time, the password may be more than 8 digits. If the input is wrong, the input needs to be updated again, and the fewer the password digits, the less secure it is, which is very inconvenient, so it is urgent to solve the above problems now.
