Method for realizing multi-touch screenshot of ATM based on conductive wire film capacitive screen

Abstract

The invention relates to a method for realizing multi-touch screen shot of an ATM (Automatic Teller Machine) based on an electric lead film capacitance screen. The electric lead film capacitance screen is supplied at first, and then the following steps are performed: (1) taking the electric lead film capacitance screen as a screen and mounting on a machine body of the ATM; (2) touching any four points in a selected area for performing rectangular screen shot by two hands of a user after the user inquires or finishes a transaction on the ATM, and generating screen shot data by an industrial personal computer of the ATM; (3) after finishing the screen shot, inputting and confirming a cell phone number through a password input unit by the user, and then sending the screen shot data to the corresponding cell phone through wireless communication equipment by the industrial personal computer. According to the method provided by the invention, the electric lead film capacitance screen with a special structure and the wireless communication equipment are utilized to realize the advantages of convenient operation of the user, capability of saving paper sheet, excellent man-machine interactivity, safety, reliability, and the like. The electric lead film capacitance screen is high in reaction sensitivity, high in positioning precision and long in service life.

Description

technical field [0001] The invention relates to a method for realizing multi-touch screen capture of an ATM based on a conductive wire film capacitive screen. Background technique [0002] At present, the existing ATM machines mainly have the following disadvantages: (1) The single-touch touch screen can only recognize and support the touch and click of one finger at a time. If more than two points are touched at the same time, For example, the multi-touch screen capture technology cannot be realized, and there are disadvantages such as insensitive response, low positioning accuracy, frequent calibration, short service life, and poor human-computer interaction; (2) using a receipt printer to Printing user transaction information wastes paper and is not environmentally friendly; (3) Using keyboard keys to input passwords requires pressing hard, and due to the existence of the baffle, users are easy to press the wrong password when pressing, and there is a risk of being peeped...
