Specifically, two commonly used file transfer methods in related technologies are: one is to realize quick pairing through NFC. The other is the HotKnot technology based on the touch screen, which pastes the screens of two mobile phones that support this technology together, and then realizes file transfer through Wi-Fi (hot spot or direct connection).

Yet there is following shortcoming or problem in above-mentioned prior art:

(1) Fast pairing and transmission based on NFC first requires hardware devices to support NFC, and also requires hardware peripheral configuration support, which will increase costs.

(2) The quick pairing technology based on HotKnot has requirements for the touch screen components and their chip firmware, as well as the software platform of the terminal, which will also increase the overall cost.

For the above-mentioned problems in related technologies, there is no effective solution at present.
