Systems and methods to facilitate repeated purchases

1. A computer-implemented method of performing transactions, comprising:

receiving, by an interchange, a top-up request from a server when the server determines that a balance of an account held by a user on the server falls below a predetermined amount due to an activity of the user on the server;

charging, by the interchange, a phone number account held by a carrier for a top-up amount in response to receiving the top-up request;

receiving, by the interchange, an indication of payment from the carrier; and

paying, with the interchange, the server based on the amount, thereby topping-up the balance of the account on the server using funds from the carrier and processing a previous payment for the phone number;

receiving, in the computing device, a message from a mobile phone having a phone number;

identifying, by the computing device in response to the message, the previous payment transaction processed by the computing device for the number;

communicating, by the computing device, with a merchant to repeat a purchase identified according to the previous payment transaction; and

processing, by the computing device, a payment to the merchant using funds associated with the phone number to repeat the purchase.

2. The method of claim 1 , wherein the user tops the balance up without having to go outside an application provided by the server.

3. The method of claim 2 , wherein an interface of the application alerts the user when the balance falls below the threshold.

4. The method of claim 3 , wherein the alert is a pop-up window.

5. The method of claim 3 , wherein an icon alerts the user.

6. The method of claim 1 , further comprising:

communicating, using the interchange, with a mobile phone at the phone number to confirm the topping-up.

7. The method of claim 6 , wherein the user is presented a message on the mobile phone to confirm repeated top-up operations.

8. The method of claim 7 , wherein after the communication to confirm the repeated top-up operations, the interchange skips a requirement to confirm with the mobile phone for subsequent topping-up operations.

9. The method of claim 6 , wherein the user confirms repeated topping-up operations based on a calendar.

10. The method of claim 6 , wherein the user confirms repeated topping-up operations on an as needed basis when the balance is below the threshold.

11. The method of claim 1 , further comprising:

communicating, using the interchange, with a server to determine if the account needs additional funds.

12. The method of claim 1 , further comprising:

requesting, using the interchange, that the server notify the interchange when the account is low.

13. The method of claim 1 , further comprising:

communicating, by the computing device, with a merchant to repeat a purchase identified according to the previous payment transaction.

14. The method of claim 1 , wherein the identifying of the previous payment transaction comprises identifying a most recent payment transaction associated with the phone number as the previous payment transaction.

15. The method of claim 1 , wherein the previous payment transaction is identified based on the message.

16. The method of claim 1 , wherein the message is a reply to a previous message transmitted from the computing device to the mobile phone in connection with the previous payment transaction.

17. The method of claim 16 , wherein the message received from the mobile phone is received via a short message service (SMS).

18. The method of claim 17 , wherein the previous message transmitted from the computing device to the mobile phone includes a code to identify the previous payment transaction.

19. The method of claim 18 , wherein the message received from the mobile phone includes the code to identify the previous payment transaction.

20. The method of claim 1 , further comprising:

communicating, by the computing device, with the mobile phone to request confirmation of a request for the previous payment transaction; and

wherein the payment to repeat the purchase is processed without the computing device communicating with the mobile phone to request confirmation.

21. The method of claim 1 , wherein the processing of the payment comprises:

transmitting, by the computing device, at least one messages to a telecommunication carrier according to the phone number;

receiving funds corresponding to the at least one message messages from the telecommunication carrier of the mobile phone; and

providing the funds to the merchant as the payment.

22. The method of claim 1 , wherein the processing of the payment comprises:

charging a financial account associated with the phone number to collect funds for the payment.

23. A non-transitory computer-readable storage media storing instructions which, when executed on a computer, cause the computer to perform a method of performing transactions, the method comprising:

receiving, by an interchange, a top-up request from a server when the server determines that a balance of an account held by a user on the server falls below a predetermined amount due to an activity of the user on the server;

charging, by the interchange, a phone number account held by a carrier for a top-up amount in response to receiving the top-up request;

receiving, by the interchange, an indication of payment from the carrier; and

paying, with the interchange, the server based on the amount, thereby topping-up the balance of the account on the server using funds from the carrier and processing a previous payment for the phone number;

receiving, in the computing device, a message from a mobile phone having a phone number;

identifying, by the computing device in response to the message, the previous payment transaction processed by the computing device for the phone number;

communicating, by the computing device, with a merchant to repeat a purchase identified according to the previous payment transaction; and

processing, by the computing device, a payment to the merchant using funds associated with the phone number to repeat the purchase.

24. A computing apparatus, comprising:

a processor;

a non-transitory computer readable medium connected to the processor;

a local storage on the non-transitory computer readable medium; and

a set of instruction on the non-transitory computer readable medium that are executable by the processor to carry out a method including:

receive a top-up request from a server when the server determines that a balance of an account held by a user on the server falls below a predetermined amount due to an activity of the user on the server;

charge a phone number account held by a carrier for a top-up amount in response to receiving the top-up request;

receive an indication of payment from the carrier; and

pay the server based on the amount, thereby topping-up the balance of the account on the server using funds from the carrier and processing a previous payment for the phone number;

receive a message from a mobile phone having a phone number;

identify, in response to the message, the previous payment transaction processed by the computing device for the phone number;

communicate with a merchant to repeat a purchase identified according to the previous payment transaction; and

process a payment to the merchant using funds associated with the phone number to repeat the purchase.
