Abstract: A transaction device, a transaction system using the same and a transaction method using the same are provided. The transaction device comprises a barcode scanner, an input unit and a verification unit. The barcode scanner is used for scanning a barcode image displayed in a mobile device. The input unit is used for receiving a verification code inputted by user after the barcode scanner scanned the barcode image. The verification unit is used for verifying whether the verification code inputted by the user is the same as an access code. If the verification code inputted by the user is the same as the access code, the verification unit outputs a verifying success signal.

Abstract: A method and a system for inputting and uploading data are disclosed. The data inputting and uploading method comprises following steps. A figure factor is generated by a user equipment according to a key rule. A dynamic keyboard is generated by the user equipment according to the figure factor, wherein the dynamic keyboard is composed of a plurality of figures. A permutation of the selected figures is recorded by the user equipment. The permutation of the selected figures is transformed into a hash code by the user equipment. The hash code is received and transformed into a plain code by a back-end device.

Abstract: The invention relates to an authorizing server, an authorizing method and a computer program product. An authorizing system server is in communication with an electronic device and an agent device. The authorizing server includes a transceiver and a processor. The transceiver receives a request issued by the electronic device. The processor provides an initial authorizing code in response to the request, and generates a server side code accordingly. After transmitting the initial authorizing code, the transceiver receives a remote side code, obtained according to the initial authorizing code. The processor authorizes an operation procedure to be executed when a predetermined condition is satisfied.
