Embodiment Construction

[0033] The terminal starts the password keypad processing flow, please refer to figure 1 ,it includes:

[0034] Step A1, judging whether the current input is completed by an external password keypad, if yes, execute step A2, otherwise exit the process;

[0035] Step A2, switch the serial port channel, switch the baud rate;

[0036] In order to ensure the success of channel and baud rate switching, set the delay, generally set the delay to 0.5 seconds;

[0037] Step A3, sending a startup command to the password keypad and prompting the user to start inputting;

[0038] Step A4, enter the terminal and interact with the password keypad data;

[0039] Step A41, enter the terminal and interact with the password keypad data;

[0040] Step A42, judging whether the user data input is complete, if yes, execute step A43, otherwise jump to step A41;

[0041] Step A43, the terminal sends an instruction to close the password keypad; in order to ensure that the password keypad is close...

Abstract

The invention discloses a wireless terminal-based password small keyboard processing method, which comprises a processing flow that a terminal initiates a password small keyboard and a processing flow that the terminal and the password small keyboard are interacted. The password small keyboard is externally connected to a wireless terminal serving as a carrier, the terminal transmits a command through a serial port to control the password small keyboard to open, close and perform multiple prompt input, and a keyboard value input by a user at the password small keyboard is transmit to the terminal through the serial port. The terminal can more reasonably interact with the password small keyboard; therefore, the user password input is independent from an operating keyboard of a terminal owner, the service transaction efficiency is improved, the password leakage can be avoided when the user inputs the password, and the method brings great practicality and convenience to service development in rural areas. In addition, the password keyboard can be initiated when the password small keyboard is needed for input, the password small keyboard is closed when the user completes the input, and the method has the energy-saving effect.

Description

Technical field [0001] The invention relates to a method for processing a small password keyboard based on a wireless terminal. Background technique [0002] With the continuous popularization of mobile communication terminals, in order to meet the needs of people's daily business handling, mobile channel business terminal products have been integrated into electronic channel services such as air number selection and air recharge. In the process of handling business, many operations will require customers to input corresponding password to complete. However, most terminals have only one keyboard for use, which causes the user and the owner (terminal device owner) to share a keyboard, which not only wastes operating time, but also involves information security issues when the user enters a password under the gaze of others. [0003] At present, some large shopping malls or banks have an external password keypad, and the user completes the password input on the password keypa...
