METHOD FOR PERFORMING BIDIRECTIONAL COMMUNICATION BY ADOPTING OPTICAL VISION CODES

摘要

A method for performing bidirectional communication by adopting the optical vision codes is disclosed in the present invention, and it uses two or more devices with at least one display unit and at least one electrical optical scan unit, the two or more devices can read the optical vision code on the display unit of each other by the electrical optical scan unit, in order to perform the bidirectional communication; the whole bidirectional communication process is processed once or many times; at least one of said devices determines whether the user identity of one or more devices is genuine or fake and/or determines the authorization of business payment through the bidirectional communication content and/or the detection process inside and/or outside of the device. In this operation flow of the method for processing bidirectional communication by adopting the optical vision codes in the present invention, the information transmission is very safe and is not easy to be intercepted by the exterior equipment; and because the payment or secret information transmission is performed after the identity verification, the operation safety is further ensured, and the user's property and the information safety are further ensured.
