Abstract: A portable electronic apparatus for timely receiving and displaying an electronic file is provided. The portable electronic apparatus is connected to a sender which transmits an electronic file to the electronic apparatus. The portable electronic apparatus includes a power unit, a receiving unit, a main part and a power controlling unit. The power unit is configured for supplying power to the portable electronic apparatus. The receiving unit is configured for timely receiving the electronic file transferred from the sender. The main part is for timely displaying the electronic file received by the receiving unit. The main part may be in either one of a “power-on” state or a “power-off” state.

Abstract: An electronic signature system is provided. The system includes a server and a database for storing a plurality of signature selections. The server includes a signature task setting module for receiving a request for signing a document which has a document type, and setting the signature procedure according to the document type; a transmitting module for simultaneously distributing the document to designated signers; a signature selection setting module for receiving a signature selection selected by each signer in real-time; a signature selection analyzing module for obtaining the signature selections, analyzing the signature selections, thereby generating an analysis result; a determining module for determining whether a current designated signer has a right to sign the document according to the analysis result; and a signature performing module for signing the document if the current designated signer has the right. An electronic signature method is also provided.

Abstract: A method for timely receiving and displaying electronic files is provided. The method includes: providing an electronic device being electrically coupled to an electronic sending device, the electronic device comprising a receiving unit and a main part, the main part being in one of a “power-on” state and a “power-off” state; receiving a want-to-send signal from the electronic sending device with the receiving unit; determining the main part is in the “power-on” state or in the “power-off” state via the power controlling unit; providing power supply to the main part under control of the receiving unit if the main part is in the “power-off” state; sending a ready-to-receive signal to inform the electronic sending device of sending an electronic file; receiving the electronic file from the electronic sending device with the receiving unit; displaying the electronic file with the main part.

Abstract: A portable electronic apparatus for receiving and displaying electronic files with identification code is provided. The identification code indicates whether the electronic file is an instant file or a common file. The portable electronic apparatus includes a main part, a data storage, and a receiving unit. The main part being selective in a “power-on” state or a “power-off” state is for displaying the electronic file and obtaining the instant electronic file from the data storage to display when the main part enters into the “power-on” state. The receiving unit is for receiving the electronic file, determining according to the identification code whether the electronic file is an instant file and whether the main part is in the “power-on” state; and storing the electronic file to the data storage and controlling the main part in the “power-on” state if the electronic file is an instant file but the main part is in the “power-off” state.
