According to a second aspect of embodiments of the present disclosure, there is provided a mobile payment device including a receiving setting module configured to set a payment operation state for a transaction to be an operation-invalid state when receiving payment information, a receiving module configured to receive a hardware operation instruction through a hardware element associated with the mobile device, a determining updating module configured to update the payment operation state set by the receiving setting module to be an operation-valid state when the hardware operation instruction received by the receiving module meets the preset condition. The preset condition includes that the hardware information in the hardware operation instruction corresponds to preset hardware information.
According to a third aspect of embodiments of the present disclosure, there is provided a mobile payment device including a processor, a memory for storing an instruction executable by the processor. The processor is configured to setting a payment operation state to be an operation-invalid state, receiving payment information for a transaction, receiving a hardware operation instruction through a hardware element associated with the mobile device, determining whether the hardware operation instruction meets a preset condition, and updating the payment operation state to be an operation-valid state when the hardware operation instruction meets the preset condition. The preset condition includes that the hardware information in the hardware operation instruction corresponds to preset hardware information.
According to a fourth aspect of the embodiments of the present disclosure, there is provided anon-transitory computer-readable storage medium having stored therein instructions that, when executed by a processor of a mobile terminal, causes the mobile terminal to perform mobile payment method. The method includes setting a payment operation state to be an operation-invalid state, receiving payment information for the transaction, receiving a hardware operation instruction through a hardware element associated with the mobile device; determining whether the hardware operation instruction meets a preset condition, and updating the payment operation state to be an operation-valid state when the hardware operation instruction meets the preset condition. The preset condition includes that the hardware information in the hardware operation instruction corresponds to preset hardware information.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the invention and, together with the description, serve to explain the principles of the invention.
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same number in different drawings represents the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the invention. Instead, they are merely examples of apparatuses and methods consistent with aspects related to the invention as recited in the appended claims.
In step S101, a payment operation state for a transaction is set to be an operation-invalid state when receiving payment information. In this embodiment, the mobile terminal may set the payment operation state to be the operation-invalid state after receiving the payment information, such as a payment amount and a payment account, etc., input by a user.
In step S102, a hardware operation instruction is received from a user.
A payment operation cannot be completed after the payment operation state being set to be the operation-invalid state. The user may click a hardware key to complete the payment operation. Thus, the mobile terminal may receive the hardware operation instruction input by the user. The hardware operation instruction includes hardware information (i.e. hardware key information) clicked by the user. For example, if a user pushed a volume up key of the mobile terminal, the hardware operation instruction includes information on the volume up key being pushed.
In step S103, the payment operation state is switched to an operation-valid state if the hardware operation instruction meets a preset condition. The preset condition includes a condition that the hardware information in the hardware operation instruction corresponds to preset hardware information. The hardware information may include the hardware key information, for example, a hardware key identifier, operation times of hardware key, etc.
In this embodiment, updating the payment operation state to be the operation-valid state when the received hardware operation instruction meets the preset condition, for example, setting the payment key to be a clickable state. Therefore, the mobile terminal may complete the payment operation after the user clicks the payment key.
With respect to the embodiment of the mobile payment method, the mobile payment operation is completed by receiving the hardware operation instruction, and by updating the payment operation state from the operation-invalid state to the operation-valid state when the received hardware operation instruction meets the preset condition. That is, the mobile payment operation may be completed only after a payment confirmation by hardware, thereby greatly improving the safety of the capital of the user.
In step S201, a hardware information list is displayed on a mobile device.
In this embodiment, the hardware information list may include one or more the following hardware keys: a volume key and a power key of the current mobile terminal, as well as one or more of a key inserted into an apparatus of a headphone jack of the current mobile terminal and a volume key on a line control earphone of the current mobile terminal. The hardware key may also include a microphone for the mobile terminal which is configured to receive a voice of a user. The volume key includes a volume-increase key and a volume-decrease key.
In step S202, a hardware selecting instruction input by the user is received, and one or more pieces of the hardware information is selected from the hardware information list according to the hardware selecting instruction.
In this embodiment, the user may select one or more pieces of the hardware information from the hardware information list after the mobile terminal displays the hardware information list to be selected by the user. When the user may select one or more pieces of the hardware information from the hardware information list, the mobile terminal receives the hardware selecting instruction input by the user, and then selects one or more pieces of the hardware information from the hardware information list according to the hardware selecting instruction. The hardware selecting instruction includes one or more pieces of the hardware information selected by the user, for example, the hardware key information.
In step S203, the preset hardware information according to one or more pieces of the selected hardware information is generated and stored. In this embodiment, the preset hardware information may be generated according to one or more pieces of the selected hardware information. For example, the preset hardware information may be generated according to one or more pieces of the selected hardware key information.
With respect to the embodiment of the mobile payment method, the user is provided with convenience to acquire the hardware information list by displaying the hardware information list, and the preset hardware information is generated by selecting one or more pieces of the hardware information from the hardware information list according to the received hardware selecting instruction, so as to provide condition for determining subsequently whether the hardware operation instruction meets the preset condition.
In step S301, the payment operation state is set to be the operation-invalid state when receiving payment information, and displaying the first prompt information.
In this embodiment, the mobile terminal may display the first prompt information when the payment operation state is set to be the operation-invalid state, for example, when the payment key is set to be in the non-clickable state. The first prompt information is configured to remind the user to implement the mobile payment with the hardware operation.
For example, the prompt information of “the mobile payment is implemented by clicking the hardware key” may be displayed to facilitate the user to complete the operation of clicking the hardware key according to the prompt information. Therefore, the user is guided to implement the subsequent operation by displaying the first prompt information.
In step S302, a hardware operation instruction is received from a user.
In this embodiment, as the user has preset the hardware information for payment confirmation (for example, the hardware key information), the user may click the preset hardware key according to the above prompt information to realize the payment confirmation of the hardware.
When the user clicks the hardware key, the mobile terminal (for example, the mobile phone) may receive the hardware operation instruction input by the user. The hardware operation instruction includes hardware key information clicked by the user.
In this embodiment, when the user presets one piece of the hardware key information for the payment confirmation, the user will click one hardware key, and at this time, the mobile terminal may receive one hardware operation instruction. When the user presets two pieces of the hardware key information for the payment confirmation, the user will click two hardware keys, and at this time, the mobile terminal may receive two hardware operation instructions. When the user presets at least three pieces of the hardware key information for the payment confirmation, the user will click at least three hardware keys, and at this time, the mobile terminal may receive at least three hardware operation instructions.
Therefore, the number of the hardware operation instruction corresponds to the number of the keys operated by the user. The mobile terminal may accurately acquire the hardware operation instruction through this corresponding relation.
In step S303, it is determined whether the hardware operation instruction meets the preset condition. If the hardware operation instruction meets the preset condition, carrying out step S304. If the hardware operation instruction does not meet the preset condition, carrying out step S305.
In step S304, the payment operation state is switched to the operation-valid state.
In this embodiment, when the preset hardware information is one piece of the hardware information, for example, one piece of the hardware key information, the preset condition may be that the hardware information in the hardware operation instruction is consistent with the preset hardware information. When the preset hardware information includes two pieces of the hardware information, for example, two pieces of the hardware key information, the preset condition may be that the hardware information in two hardware operation instructions received in order is consistent with the preset hardware information, and the time interval between the two hardware operation instructions is less than a first preset threshold. The first preset threshold may be 50 millisecond or 100 millisecond. As the first preset threshold is very small, it may be considered that the two hardware operation instructions are received at the same time. That is, the user needs to click two hardware keys at the same time. When the preset hardware information includes at least three pieces of the hardware information, for example, three pieces of the hardware key information, the preset condition may be that the hardware information in at least three hardware operation instructions received in order is consistent with the preset hardware information, and the time interval between the two adjacent hardware operation instructions is less than a second preset threshold. The second preset threshold may be 1.5 seconds.
Noted that when the preset hardware information includes two or more pieces of the hardware information, the received order of the hardware operation instructions may be set. Therefore, when determining whether the hardware operation instruction meets the preset condition, the received order of the hardware operation instructions is taken as one portion of the above preset condition determination. That is, it is determined that the order of the preset condition is met when the received order of the hardware operation instructions is consistent with the stored order of the hardware information included in the preset hardware information. Of course, the received order of the rest of the hardware operation instructions may also be set by the user or a system.
For example, the preset hardware information is key 1, key 3 and key 2. If the hardware information in at least three hardware operation instructions received in order are the key 1, the key 3 and key 2 respectively, and the time interval of two adjacent hardware operation instructions is less than 1.5 seconds, the hardware operation instruction meets the preset condition. If the hardware information in at least three hardware operation instructions received in order is the key 1, the key 2 and the key 3 respectively, the hardware operation instruction does not meet the preset condition as the orders of the above two sequence do not correspond to each other.
Therefore, in this embodiment, as the preset hardware information is different, the way of determining whether the hardware operation instruction meets the preset condition is different, thereby realizing a flexible means. Meanwhile, when the preset hardware information includes a plurality of pieces of the hardware information, the hardware is more difficult to be confirmed. Therefore, the safety of the mobile payment may be greatly improved.
In step S305, the number of times that the hardware operation instruction does not meet the preset condition is determined. If the hardware information in the received hardware operation instruction does not correspond to the preset hardware information, the hardware operation instruction does not meet the preset condition. In the embodiment, the number of times that the hardware operation instruction does not meet the preset condition need to be accounted.
In step S306, it is determined whether the counting times equals to the preset times. If the number of times equals to the preset times, carrying out step S307. If it is less than the preset times, carrying out step S308.
In step S307, the current mobile payment operation is cancelled. If the number of times that the hardware operation instruction does not continuously meet the preset condition is equal to the preset times, for example, three times, the current mobile payment operation is canceled.
In step S308, second prompt information is displayed, and the hardware operation instruction is received from the user and then the process returns to step S303.
If the number of times that the hardware operation instruction does not continuously meet the preset condition is one time, which is less than the preset times, the second prompt information may be displayed. The second prompt information is configured to remind the user to re-implement the mobile payment with the hardware operation. When the user clicks the hardware key according to the second prompt information, the mobile terminal receives the hardware operation instruction re-input by the user and then determines whether the hardware operation instruction meets the preset condition. If the hardware operation instruction meets the preset condition, the payment operation state may be updated to be the operation-valid state, to complete the mobile payment operation. If it does not meet the preset condition, the number of times that the hardware operation instruction does not continuously meet the preset condition are two times. As the two times is less than the preset times three, the second prompt information is continuously displayed and the hardware operation instruction re-input by the user is received. If the hardware operation instruction still does not meet the preset condition, the number of times that the hardware operation instruction does not continuously meet the preset condition are three times. Therefore, the current mobile payment operation is cancelled.
With respect to the above embodiment of the mobile payment method, the current mobile payment operation is cancelled when the number of times that the hardware operation instruction does not continuously meet the preset condition equals to the preset times, so that an illegal user cannot implement the mobile payment operation, thereby avoiding the capital loss to the user. The second prompt information is displayed when the number of times that the hardware operation instruction does not continuously meet the preset condition is less than the preset times, to remind the user how to implement the subsequent operation, and therefore provide the user with convenience.
With the combination of
With respect to the above embodiments, the mobile payment operation is completed with the manner of payment conformation of both software and hardware, thereby greatly increasing the safety of the capital of the user and effectively avoiding the capital loss to the user.
In step S401, the payment operation instruction is received from a the user.
The payment operation instruction includes operation gesture information. The operation gesture information may include, but is not limited to, a click, a sliding operation and other operations with a track.
For example, in step S101, after receiving the payment amount, the payment account and the payment code input by the user, the mobile terminal sets the payment operation state to be the operation-invalid state (that is, sets the payment key to be in the non-clickable state), then receives the hardware operation instruction input by the user, and updates the payment operation state to be the operation-valid state when the hardware operation instruction meets the preset condition. After updating the payment operation state to the operation-valid state, that is, after setting the payment key to be in the clickable state, the mobile terminal may acquire the click operation of the payment key by the user.
In addition, the payment operation instruction may still include voice information, fingerprint information, etc. Assuming that the payment information in step S101 does not include the payment code, the information prompting the user to input code may be displayed when the payment key is clicked. At this time, the user may input the code with a voice manner or may input a fingerprint code. Correspondingly, the payment operation instruction may include the voice information or the fingerprint information.
In step S402, a payment result is displayed when the payment operation instruction meets a preset payment condition.
The preset condition may include that the payment key is triggered, and also may include that the code included in the payment operation instruction (such as the voice code and the fingerprint code) is consistent with a preset code.
In this embodiment, the payment result, for example, the payment completion or an insufficient balance is displayed, when the payment operation instruction meets the preset payment condition.
In addition, it needs be described that the above step of acquiring the payment operation instruction may be implemented before or after the hardware operation instruction is acquired. This embodiment does not limit the implementing order of acquiring two operation instructions. The above payment result is further displayed when the two above instructions meet the condition corresponding to these instructions, respectively.
