Problems solved by technology
[0005] However, it is too expensive to read the signal transmitted from the RF chip or infrared chip in the mobile communication terminal, that is, the traditional receiving part, that is, the reading machine (such as RF, infrared, bar code, etc.) (such as: a reading machine) machine is hundreds of thousands of won), and the market infrastructure cost for the manufacturers and operators of reading machines is too high, so the traditional basis of using mobile communication terminals for small settlements has not been established.
[0006] At the same time, in the above-mentioned situation, in order to carry out small-amount settlement, the user must purchase a mobile communication terminal equipped with an RF chip or an infrared chip; However, this has caused great inconvenience to the operation
Whether a system can be promoted and applied will depend on whether users respond; for this reason, the practicality of the above-mentioned system can only become very low
[0007] In addition, the disadvantage of the traditional reading machine is that it can only be applied in the simple small-amount settlement field; it is impossible to be applied in the securities coupon identification procedure with a complicated management system

Embodiment Construction
[0035] An example of the present invention will be described below with reference to the accompanying drawings.
[0036] figure 1 It is an overview of the structure of a small-amount settlement system using the backlight signal of a mobile communication terminal as an example of the present invention; and figure 2 It is a detailed diagram of a mobile communication terminal and a light receiving unit according to an example of the present invention.
[0037] figure 2 In an example of the present invention, it is a mobile communication terminal capable of small-amount settlement and having a sending function. It consists of a central control unit (11), a screen unit (12), an illumination control unit (13) and an illumination unit (14). Among them, the lighting control part is a device with a signaling function that converts the identification information required for small-amount settlement into optical signals for transmission; it will control the backlight of the screen p...

This invention relates to a small amount settle account technology to convert the acceptance information into a light signal combined by brightness, greyness and color by controlling backlight signal settle account of the device picture part, then to let a convertible light reader read and judge directly to save the expenses for building market infrastructures to lay a foundation for small amount settle account with mobile communication terminal devices on the basis of linking the light signal and a bill structure of an acceptance server in serial communication in the environment suitable for personal computer and Internet.
Description
technical field [0001] The present invention relates to an invention related to the small amount settlement technology using mobile communication terminals (such as mobile phones, cellular phones, PDA, PCS, CDMA-2000, IMT-2000, etc.). That is to say, the invention converts the identification information into the light composed of brightness, gray scale and color by controlling the settlement mode program of the backlight function (such as: TFT, LCD, EL, organic EL, etc.) of the mobile communication terminal. signal (flash signal); then this optical signal is read and judged by the optical reader of the receiving part, so that it is linked with the billing mechanism of the settlement confirmation server, and a mobile communication terminal that can immediately complete small settlement A method for small-amount settlement using machine backlight signals. Background technique [0002] As we all know, the traditional micro-payment technology using mobile communication terminal...
