Examples
In this embodiment, two NFC communication modes of the file sharing end and the file acquiring end are described through different scenes:
a point-to-point mode: the mode is mainly used for personal sharing of individuals on the spot, and the sharing steps are as follows:
step one, two mobile terminals supporting an NFC function install application programs for file sharing and management, wherein one mobile terminal opens the application program, designates a file (stored in a cloud) to be shared, and stays on an interface after the NFC sharing function is started; and the other mobile terminal opens an application program, opens an NFC sharing search interface and approaches the terminal with the sharing established.
And step two, when the two mobile terminals approach to a certain degree (within 10cm), communication is established, the terminals needing to acquire the shared files acquire identification information of the files, the corresponding files are acquired after the application to the cloud end is passed, the files are added into the account of the user, and the user can read the files through the application program at any time.
The scene is mainly suitable for more communication with the client, and the client can be guided to perform more communication with the staff in a point-to-point mode. Taking a campaign as an example, as shown in fig. 5, the system is composed of three roles, which are a file sharer, a file receiver, and a cloud manager from left to right, where the file sharer and the file receiver install application programs for file sharing and management on a mobile terminal through mobile terminals that support NFC functions and are carried by the mobile terminals, and NFC communication can be performed between the application programs.
In this embodiment, a file sharer, i.e., an activity host, may open an application to establish NFC file sharing if a user needs more data when publicizing a product, and share files corresponding to the client face to face.
The cloud manager is responsible for auditing the files to be shared, the files can be stored in the cloud only according with sharing conditions, and file sharing is controlled.
The file receiver, namely the activity participant, can communicate with the staff and obtain the shared file through the mobile terminal if the activity content is interested in the activity site.
II, reading mode: the mode is mainly used for one-to-many group sharing
Step one, preparing an NFC card, and writing related information into the NFC card after a file to be shared is stored in a cloud;
and step two, preparing a mobile terminal supporting the NFC function, opening an application program, opening an NFC sharing search interface, and enabling the terminal to approach the prepared NFC card.
And step three, when the terminal approaches to a certain degree (within 10cm), reading the file identification information in the card, obtaining a corresponding file after passing the application to the cloud, adding the file into the account of the user, and reading the file by the user through the application program at any time.
The mode is mainly suitable for free file sharing of a user group in a public place. Taking a public newspaper as an example, referring to fig. 5, the system is composed of three roles, namely a file sharer, a file receiver, and a cloud manager from left to right.
In this embodiment, the sharer is a public newsstand, and through this kind of mode, public newsstand only needs to show newspaper content brief introduction on electronic screen, place an NFC card below this electronic screen, share file information is stored in the NFC card, if pedestrian (file receiver) are interested in newspaper content, can open application's NFC file sharing search interface, be close to the NFC card with the terminal and can acquire complete newspaper, and simultaneously, newsstand content updates also need not manual operation at every turn, only need to update newsstand content brief introduction networking to electronic screen, and the NFC card only records the mark that this newsstand corresponds simultaneously, and the file that corresponds at the high in the clouds update can realize 24 hours unmanned newsstand.
And the cloud manager is responsible for auditing and updating the files to be shared.
Sharing file receivers are pedestrians who pass by, when the newspapers need to be seen, the newspapers and periodicals can be obtained and read by approaching the NFC card through the application program, and resources are saved while the newspapers and periodicals are selected to be read by oneself.
In summary, according to the scene-based file sharing system and method based on NFC, by utilizing the file sharing terminal and the file acquiring terminal which support the NFC function, when the file sharing terminal and the file acquiring terminal are close to each other and are within a communication distance specified by NFC, communication is established between the file sharing terminal and the file acquiring terminal based on NFC, and after NFC communication is established between the file sharing terminal and the file acquiring terminal, the file acquiring terminal acquires the file to be shared by the file sharing terminal from the file sharing terminal, so that the purpose of saving paper resources and expanding the file sharing efficiency is achieved.
The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention.
