Abstract: A data capturing method of near-field communication (NFC) protocol and an NFC electronic device thereof are provided. The method can be applied to an NFC electronic device with an operation system, and the operation system includes a kernel mode and a user mode. The method includes following steps: detecting a readable element by an interface drive module in the kernel mode to obtain NFC original data transferred by the readable element; capturing the NFC original data from the interface drive module by a capturing module and outputting the NFC original data to an analyzing module in the user mode; and analyzing the NFC original data by the analyzing module to obtain NFC target data.

Abstract: A data transmission system includes a plurality of electronic devices, an verification server, and at least one access server. The electronic devices are verified by the verification server, and a data transmission group formed by the verified electronic devices. A receiving end in the data transmission group sends a command to the rest of the electronic devices in the data transmission group by the verification server. When the rest of the electronic devices receive the command, the rest of the electronic devices output metadata to the access server. The receiving end receives the metadata via the access server. The receiving end requests the transmitting end in the data transmission group for a physical file according to the metadata. The transmitting end transmits the physical file to the access server, and the access server transmits the physical file to the receiving end.
