System and method of secure payment transactions

1. A method of authenticating a debit card payment transaction, comprising:

receiving, by one or more processors of an adaptive payment server, a debit card number associated with the debit card payment transaction from a first communication device over a first communication channel;

generating, by the adaptive payment server, a transaction identifier that uniquely identifies the debit card payment transaction;

communicating, by the adaptive payment server, the transaction identifier to the first communication device over the first communication channel;

identifying, by the adaptive payment server, a second communication device based on the debit card number;

initiating, by the adaptive payment server, a second communication channel with the second communication device, wherein the first communication channel is different from the second communication channel;

communicating, by the adaptive payment server, the transaction identifier to the second communication device over the initiated second communication channel;

receiving, by the adaptive payment server, a Personal Identification Number (PIN) associated with the debit card number from the second communication device over the second communication channel; and

authenticating, by the adaptive payment server, the debit card payment transaction using the debit card number and the PIN.

2. The method of claim 1 , further comprising:

encrypting the PIN after the PIN is received by the adaptive payment server.

3. The method of claim 1 , wherein the first communication channel is over a data network.

4. The method of claim 1 , wherein the second communication channel is a voice network.

5. The method of claim 4 , wherein the voice network includes a public switched telephone network.

6. The method of claim 1 , wherein the second communication device includes a telephone function, and wherein the second communication device is identified by a telephone number.

7. The method of claim 6 , wherein said initiating a second communication channel further comprises:

calling, by an interactive voice response (IVR) system associated with the adaptive payment server, the second communication device using the telephone number; and

prompting, through the second communication device, input of the PIN.

8. The method of claim 1 , wherein the first communication device and the second communication device are different devices.

9. The method of claim 1 , wherein the first communication device and the second communication device is the same device.

10. A system of authenticating a debit card payment transaction, comprising:

an adaptive payment server comprising:

one or more processors, and non-transitory memory coupled to the one or more processors, the memory configured to store instructions that on execution by the one or more processors cause the one or more processors to perform:

receiving receive a debit card number from a first communication device over a first communication channel;

generating a transaction identifier that uniquely identifies the debit card payment transaction;

communicating communicate the transaction identifier to the first communication device over the first communication channel;

identifying identify a second communication device based on the debit card number;

initiating initiate a second communication channel with the second communication device, wherein the first communication channel is different from the second communication channel;

communicating communicate the transaction identifier to the second communication device over the initiated second communication channel;

receiving receive a Personal Identification Number (PIN) associated with the debit card number from the second communication device over the second communication channel; and

authenticating authenticate the debit card payment transaction using the debit card number and the PIN.

11. The system of claim 10 , wherein the one or more processors of the adaptive payment server are further perform:

encrypting the PIN after the PIN is received by the adaptive payment server.

12. The system of claim 10 , wherein the first communication channel is over a data network.

13. The system of claim 10 , wherein the second communication channel is a voice network.

14. The system of claim 13 , wherein the voice network includes a public switched telephone network.

15. The system of claim 10 , wherein the second communication device includes a telephone function, and wherein the second communication device is identified by a telephone number.

16. The system of claim 15 , wherein initiating the second communication channel further comprises:

calling, by an interactive voice response (IVR) system associated with the adaptive payment server, the second communication device using the telephone number; and

prompting prompt, through the second communication device, input of the PIN.

17. The system of claim 10 , wherein the first communication device and the second communication device are different devices.

18. The system of claim 10 , wherein the first communication device and the second communication device is the same device.

19. The method of claim 1 , further comprising:

receiving, by the adaptive payment server, third identification information via the first communication channel or the second communication channel, the third identification information comprising one or more of: a global positioning system (GPS) information from the second communication device, a prerecorded verbal utterance from a payor, or an Internet Protocol (IP) address.

20. The method of claim 19 , further comprising:

receiving, by the adaptive payment server, fourth identification information via the first communication channel or the second communication channel, the fourth identification information comprising one or more of: a global positioning system (GPS) information from the second communication device, a prerecorded verbal utterance from a payor, or an Internet Protocol (IP) address.

21. The method of claim 20 , further comprising:

receiving, by the adaptive payment server, fifth identification information via the first communication channel or the second communication channel, the fifth identification information comprising one or more of: a global positioning system (GPS) information from the second communication device, a prerecorded verbal utterance from a payor, or an Internet Protocol (IP) address.

22. The system of claim 10 , wherein the one or more processors of the adaptive payment server are further perform:

receiving receive third identification information via the first communication channel or the second communication channel, the third identification information comprising one or more of: a global positioning system (GPS) information from the second communication device, a prerecorded verbal utterance from a payor, or an Internet Protocol (IP) address.

23. The system of claim 22 , wherein the one or more processors of the adaptive payment server are further perform:

receiving receive, by the adaptive payment server, fourth identification information via the first or the second communication channel, the fourth identification information comprising one or more of: a global positioning system (GPS) information from the second communication device, a prerecorded verbal utterance from a payor, or an Internet Protocol (IP) address.
