Detailed description of the invention
Fig. 1 is the process of the first preferred embodiment of the payment cipher input processing method the present invention is based on mobile terminal Figure.
Fig. 2 is that the function of the first preferred embodiment of the payment cipher imput process system the present invention is based on mobile terminal is former Manage block diagram.
Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer and more explicit, right as follows in conjunction with drawings and embodiments The present invention is further described.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and do not have to It is of the invention in limiting.
Referring to Figure 1, Fig. 1 is the first preferably implementation of the payment cipher input processing method the present invention is based on mobile terminal The flow chart of example.A kind of payment cipher input processing method based on mobile terminal shown in FIG. 1, comprising the following steps:
Step S100, the payment cipher of mobile terminal is written to the band NFC function being provided separately with mobile terminal in advance In the password holding unit of energy;The password holding unit is arranged in an intelligent wearable device.
In present pre-ferred embodiments, need in advance by the payment cipher of mobile terminal (as carried out online shopping payment, rubescent Wrap, go back credit card, wait the payment cipher of pecuniary exchanges) it is written to a password holding unit with NFC function, the band NFC function Password holding unit be provided separately with mobile terminal.Wherein, bracelet, intelligence are intelligently being dressed in the password holding unit setting Wearing sets wrist-watch, intelligence is dressed in ring.
Wherein, the NFC, full name are that Near Field Communication --- near-field communication, there are three types of NFC functions Mode are as follows: reading mode, mode card, ad hoc mode, reading mode are similar to reader function, card mold for read/write card (or TAG) Formula can be read for being modeled to card by other readers, and ad hoc mode with other equipment for communicating wirelessly.
It is described that the payment cipher of mobile terminal is written to a band NFC being provided separately with mobile terminal in the present embodiment It is specifically included in the password holding unit of function:
1) program of mobile terminal write-in password, is opened, mobile terminal starts the proximity test function at the back side;The present embodiment In, the proximity test function at the starting mobile terminal back side is positioned proximate to sensor at the mobile terminal back side, for detecting Whether the mobile terminal back side has object close.
2), when mobile terminal has detected object close in distance (such as 10 centimetres) range, mobile terminal is opened Dynamic NFC, is set as ad hoc mode;Wherein ad hoc mode with other equipment for communicating wirelessly.
3), mobile terminal and password holding unit communicated (password holding unit be usually arranged NFC be point-to-point mould Formula, so when password holding unit NFC be ad hoc mode);After communicating successfully, mobile terminal sets NFC to read mould Formula (password holding unit will set mode card for NFC after communicating successfully);NFC is set card mold by password holding unit Formula;Wherein, mode card can be read for being modeled to card by other readers.
The communication refers to that mobile terminal and password holding unit carry out data communication to increase safety, specifically: A string of legal data are pre-saved inside password holding unit, mobile terminal is establishing NFC point pair with password holding unit When point communication, burst of data is sent to password holding unit, password holding unit judges this string data, then leads to if legal It interrogates successfully;NFC is set reading mode by mobile terminal later, and NFC is set mode card by password holding unit.
4), the password that mobile terminal inputs user on interface is written in the NFC chip of password holding unit;Write-in After the completion, mobile terminal closes NFC, and NFC is set ad hoc mode by password holding unit.
Step S200, when mobile terminal needs to input payment cipher, the proximity test at the mobile terminal control starting back side Function;
In the present embodiment, it is positioned proximate to sensor at the mobile terminal back side, for detecting whether the mobile terminal back side has object Body is close;In this way, can star the proximity test function at the mobile terminal back side.When mobile terminal needs to input payment cipher, The proximity test function at the mobile terminal control starting back side.
Step S300, by the password holding unit with NFC function close to the mobile terminal, when mobile terminal and password are protected When memory cell distance is in a preset range, mobile terminal control starting NFC function.
By the password holding unit with NFC function close to the mobile terminal, when mobile terminal and password holding unit away from From when a preset range (such as 10 centimetres) is interior, mobile terminal control starts NFC function.
Step S400, mobile terminal reads payment cipher from password holding unit by NFC function.
Wherein, mobile terminal reads payment cipher from password holding unit by NFC function and specifically includes: D1, movement are eventually The operational order that end receives user opens the program of mobile terminal write-in password, and mobile terminal starts the proximity test function at the back side Energy.
D2, when mobile terminal to detected object close to and when a predetermined distance range (such as 10 centimetres) is interior, move Dynamic terminal starts NFC, is set as ad hoc mode.Wherein, ad hoc mode with other equipment for communicating wirelessly.
D3, mobile terminal and password holding unit are communicated, and (it is point-to-point mould that NFC, which is usually arranged, in password holding unit Formula, so when password holding unit NFC be ad hoc mode);After communicating successfully, mobile terminal sets NFC to read mould Formula (password holding unit will set mode card for NFC after communicating successfully);NFC is set card mold by password holding unit Formula;Wherein, mode card can be read for being modeled to card by other readers.
Wherein, the communication refers to that mobile terminal and password holding unit carry out data communication to increase safety, has Body are as follows: a string of legal data are pre-saved inside password holding unit, mobile terminal is establishing NFC with password holding unit When point-to- point communication, burst of data is sent to password holding unit, password holding unit judges this string data, if legal Then communicate success;NFC is set reading mode by mobile terminal later, and NFC is set mode card by password holding unit.
D4, mobile terminal read password from password holding unit;After the completion of reading, mobile terminal closes NFC, and password is protected NFC is set ad hoc mode by memory cell.
The payment cipher input processing method based on mobile terminal, wherein the step S400 further include: if Not reading password successfully from password holding unit yet more than certain predetermined time T1 then prompts payment to fail.
