In the embodiment of the invention, the information of the signal strength of the antenna is obtained, whether the signal strength is greater than a preset signal strength threshold value or not is judged, and if not, the information of moving the mobile terminal is output. According to the embodiment of the invention, after the information of the signal intensity of the antenna is acquired, whether the signal intensity is greater than the preset signal intensity threshold value or not is determined according to the information of the signal intensity, so that whether card swiping failure is caused by card swiping position deviation or not can be accurately known, and the user experience is improved.

In the embodiment of the present invention, in the process of acquiring the information on the signal strength of the antenna, the mobile terminal may directly acquire the information on the signal strength of the antenna at the NFC controller interface, or may not directly acquire the information on the signal strength of the antenna at the NFC controller interface NCI, in order to acquire the information on the signal strength of the antenna, it is necessary to determine whether to acquire the information on the signal strength of the antenna from the NFC controller interface NCI, if so, directly determine whether the signal strength is greater than a preset signal strength threshold, if not, receive the information on the signal strength of the antenna from the NCI, the NFC in the mobile terminal may report the information on the signal strength of the antenna in an active broadcast manner, and after acquiring the information on the signal strength of the antenna, the mobile terminal performs the step of determining whether the signal strength is greater than the preset signal strength threshold.
Example 3:
in order to determine whether the mobile terminal is capable of successfully communicating, on the basis of the foregoing embodiments, in an embodiment of the present invention, the determining whether the signal strength is greater than a preset signal strength threshold includes:
determining a quotient of the signal strength and a stored signal strength maximum;
and judging whether the quotient is larger than a preset proportion threshold value or not.
In the embodiment of the present invention, after the information of the signal intensity of the antenna is acquired, in order to determine whether the relative position between the antenna of the current mobile terminal and the antenna of the card reader such as the point-of-sale terminal is in the correct position state, that is, whether the communication between the mobile terminal and the card reader such as the point-of-sale terminal is successful or not, a signal intensity threshold may be preset, and whether the communication is successful or not may be determined by determining whether the acquired signal intensity of the antenna is greater than the preset signal intensity threshold.

In the embodiment of the present invention, whether the mobile terminal can successfully communicate is determined based on a comparison between a quotient of the obtained signal intensity of the antenna and a maximum value of the signal intensity stored in the mobile terminal and a preset proportional threshold, wherein each maximum value of the signal intensity corresponding to each card reader such as a point-of-sale terminal is different, but each maximum value of the signal intensity corresponding to any two card readers such as two point-of-sale terminals is within a preset difference range, so as to conveniently and accurately determine the maximum value of the signal intensity, the maximum values of the signal intensity corresponding to each card reader such as each point-of-sale terminal can be unified, specifically, in an initial state, that is, when the mobile terminal swipes for the first time, the maximum value of the signal intensity stored in the mobile terminal is unifiedThe maximum value of the signal intensity may be an average value of maximum signal intensities of the card readers such as the conventional point-of-sale terminals, for example, taking four conventional point-of-sale terminals as an example, if the maximum values of the information of the signal intensity that the four conventional point-of-sale terminals can provide are x respectively 1 、x 2 、x 3 、x 4 The maximum value of the signal strength information stored in the mobile terminal is

saving the signal information of intensity;
and judging whether the updating condition of the signal strength threshold value is met, if so, updating the stored maximum value of the signal strength according to the stored information of each signal strength.
In the embodiment of the invention, after the information of successful card swiping is output, the information of the signal intensity is stored, since the maximum value of the signal intensity pre-stored in the mobile terminal is determined according to the average value of the maximum signal intensity of the card readers such as the conventional point-of-sale terminals when the mobile terminal is in the initial state, that is, the mobile terminal swipes the card for the first time, in order to improve the accuracy of the maximum signal intensity of the card readers such as the point-of-sale terminals, the information of the signal intensity is stored after the mobile terminal is determined to be successful in card swiping, and the stored maximum value of the signal intensity is updated when the update condition of the limited intensity threshold is met.
The condition for satisfying the update of the signal strength threshold may be that the number of the saved signal strength information reaches a preset number threshold, or a time threshold is preset, and the time interval between the current time and the last time of update reaches the time threshold.
Specifically, after determining that the update condition of the signal strength threshold is satisfied, the stored maximum signal strength value is updated according to the stored information of each signal strength, and specifically, according to the stored information of the signal strength, the stored maximum signal strength value is updated by determining an average value of the signal strengths according to the stored signal strengths and the currently stored maximum signal strength value, and using the average value as the updated maximum signal strength value, or by searching for a maximum value of the stored signal strengths and the currently stored maximum signal strength value, and using the maximum value as the updated maximum signal strength value.
Example 5:
in order to determine whether the mobile terminal is capable of successfully communicating, in the embodiment of the present invention, on the basis of the above embodiment, the information of the signal strength is a signal strength indicator or a gain value.
When the relative position between the antenna of the mobile terminal and the antenna of the card reader such as the point-of-sale terminal is not in the normal state, the farther the distance between the antenna of the mobile terminal and the card reader such as the point-of-sale terminal is, the more the relative position between the antenna and the card reader such as the point-of-sale terminal is, the lower the coupling degree of the antenna is, the smaller the Field strength induction value is, the smaller the received signal strength indication or gain value is, the closer the distance between the antenna of the mobile terminal and the card reader such as the point-of-sale terminal is, the more the relative position between the antenna and the card reader such as the point-of-sale terminal is, the higher the coupling degree of the antenna is, the larger the Field strength induction value is, and the larger the received signal strength indication or gain value is, so as to determine whether the mobile terminal can successfully communicate, the information of the signal strength indication or gain value can be provided by a Near Field Communication Chip (NFCC), and the mobile terminal and the card reader such as the point-of-sale terminal and the like can successfully communicate on the basis of Near Field Communication.
