[0005] Further, in step S3, the mobile terminal contacts the electronic tag, and the step of the electronic tag starting data sending time T1 includes: A1, the electronic tag sends Mac address data, and the software of the mobile terminal responds; A2, the mobile terminal determines whether the information corresponding to the electronic tag data is received within the T1 time, if so, it proceeds to step A3, otherwise, returns to step A1; A3, the data information of the electronic tag is verified.

[0006] Further, in step S4, the electronic tag turns on MD5 verification, and the step of sending NFC data to the mobile terminal includes: B1, the Mac of the electronic tag generates MD5 encryption information, and sends the corresponding decryption information to the software on the mobile terminal; B2, the software on the mobile terminal receives the Mac information of the electronic tag, and determines whether it contains MD5 decryption information. If so, it goes to step B3, otherwise, it goes to step 1; B3, sending the NFC data of the electronic tag to the software on the mobile terminal.

[0007] Furthermore, the NFC data includes product information, visited websites, product promotions, product inventory, and product ratings.

[0008] Furthermore, the remote wireless system synchronously updates the NFC data of the electronic tag during the phase of binding the Mac address of the electronic tag.

[0009] This solves the technical problem of conveniently feeding back information related to electronic tags in related technologies. BRIEF DESCRIPTION OF THE DRAWINGS
