at the server,

receiving, from the first client, the identification information of the first user, the payment information, and the first geographical location;

encoding the identification information of the first user, the first geographical location, and the payment information using a first algorithm to generate a payment password;

sending the payment password to the first client;

receiving, from the second client, the identification information of the second user, the payment password, and the second geographical location;

decoding the payment password received from the second client using a second algorithm that corresponds to the first algorithm to obtain the identification information of the first user, the first geographical location, and the payment information;

determining that a distance between the first geographical location obtained from the decoding and the second geographical location meets a threshold distance; and

executing a payment operation between the first user and the second user according to the payment information in response to the determining that the distance between the first geographical location and the second geographical location meets the threshold distance.

2. The method of claim 1 , wherein the first geographical location is automatically detected by a positioning module of the first terminal device.

3. The method of claim 2 , wherein the positioning module includes one or more of a handset-based positioning module and a network-based positioning module.

4. The method of claim 1 , comprising:

at the first client,

encrypting the payment password; and

transmitting the encrypted payment password to the second client; and

at the second client,

decrypting the encrypted payment password to obtain the payment password.

5. The method of claim 1 , comprising:

at the first client, displaying the payment password on a display device of the first terminal device.

6. A method, comprising:

at a server,

receiving, from a first client, payment information and a first geographical location of a terminal device that is used to access the first client;

encoding the first geographical location and the payment information using a first algorithm to generate a payment password corresponding to the first geographical location and the payment information;

sending the payment password to the first client;

receiving, from a second client, the payment password and a second geographical location of a terminal device that is used to access the second client;

decoding the payment password received from the second client using a second algorithm that corresponds to the first algorithm to obtain the payment information and the first geographical location;

determining that a distance between the first geographical location obtained from the decoding and the second geographical location meets a threshold distance; and

executing a payment operation according to the payment information in response to the determining that the distance between the first geographical location and the second geographical location meets the threshold distance.

7. The method according to claim 6 , comprising:

receiving identification information of a first user sent by the first client;

receiving identification information of a second user sent by the second client; and

wherein the executing the payment operation includes linking the identification information of the first user, the identification information of the second user and the payment information.

8. The method according to claim 6 , wherein the payment password comprises one or more of a numeric string, a character string, and a natural language text.

9. The method according to claim 6 , wherein the determining that the distance between the first geographical location and the second geographical location meets the threshold distance includes:

querying whether there is a matching payment password within the threshold distance from the second geographical location.

10. The method of claim 6 , wherein the payment password conceals the first geographic location.

11. The method of claim 6 , wherein the threshold distance is determined as a distance for a face-to-face interaction between users of the first client and the second client.

12. The method of claim 6 , wherein the encoding the payment information and the first geographic location includes encoding the payment information and the first geographic location with a random factor.

13. A system, comprising:

a server including a processor and a memory device storing executable instructions, wherein the processor executes the executable instructions to:

receive, from a first client, payment information and a first geographical location of a first terminal device that is used to access the first client;

encode the payment information and the first geographic location received from the first client using a first algorithm to generate a payment password corresponding to the first geographical location and the payment information;

send the payment password to the first client;

receive, from a second client, the payment password and a second geographical location of a second terminal device used to access the second client;

decode the payment password received from the second client using a second algorithm corresponding to the first algorithm to obtain the first geographic location and the payment information;

determine that a distance between the first geographical location and the second geographical location meets a threshold distance; and

in response to that the distance between the first geographical location obtained from the decoding and the second geographical location meets the threshold distance, execute a payment operation according to the payment information obtained from the decoding.

14. The system according to claim 13 , wherein the payment password comprises one or more of a numeric string, a character string, and a natural language text.

15. The system according to claim 13 , wherein the determining that the distance between the first geographical location and the second geographical location meets the threshold distance includes querying whether there is a matching payment password within the threshold distance from the second geographical location.

16. The system according to claim 13 , comprising:

the first client including a processor and a memory device storing executable instructions, wherein the processor executes the executable instructions to:

obtain the payment information and the first geographical location of the first terminal device;

send the payment information and the first geographical location to the server; and

receive the payment password returned by the server.

17. The system according to claim 13 , comprising:

the second client including a processor and a memory device storing executable instructions, wherein the processor executes the executable instructions to:

obtain the payment password;

obtain the second geographical location of the second terminal device; and

send the second geographical location and the obtained payment password to the server.

18. The system of claim 17 , wherein the second client obtains the payment password from a user input or from the first client upon a user instruction.

19. The system of claim 17 , wherein the second client automatically obtains the second geographic location without interference by the second user.

20. A device, comprising:

a memory, storing a payment program of executable instructions; and

a processor, operable to execute the instructions of the payment program to perform following acts:

at a server,

receiving, from a first client, payment information and a first geographical location of a terminal device that is used to access the first client;

encoding the payment information and the first geographic location using a first algorithm to generate a payment password corresponding to the first geographical location and the payment information;

sending the payment password to the first client;

receiving, from a second client, the payment password and a second geographical location of a terminal device that is used to access the second client;

decoding the payment password received from the second client using a second algorithm corresponding to the first algorithm to obtain the payment information and the first geographic location;

determining that a distance between the first geographical location obtained from the decoding and the second geographical location meets a threshold distance; and

in response to the determining that the distance between the first geographical location and the second geographical location meets the threshold distance, executing a payment operation according to the payment information.
