Simulating I/O using multicomputer data processing
Methods, systems, and computer program products are included for simulating I/O. An exemplary method includes simulating I/O from a card that includes a magnetic stripe. The method includes receiving, at a first controller, a first token from a first terminal. The first token is communicated from the first controller to at least one backend computing device. The first controller receives, from the at least one backend computing device, a second token generated at the at least one backend computing device. The first controller injects the second token into a second controller. The second controller communicates the second token to the at least one backend system.
1. A system comprising:
a non-transitory memory; and
one or more hardware processors coupled to the non-transitory memory and configured to read instructions from the non-transitory memory to cause the system to perform operations comprising:
receiving a first token read from a token input device;
transmitting the first token over a network to at least one backend computing device;
receiving, from the at least one backend computing device, a second token that is different than the first token;
simulating input including a magnetic stripe input or a key press input; and
providing the simulated input to a transaction processing device.
2. The system of claim 1 , wherein the token input device comprises a chip card or a mobile phone.
3. The system of claim 1 , wherein the first token is readable by a chip reader device.
4. The system of claim 1 , wherein the first token comprises a numeric or alphanumeric string that represents a private key or a primary account number.
5. The system of claim 1 , wherein simulating the magnetic stripe input includes generating a magnetic signal that transmits the second token to a magnetic stripe reader corresponding to the transaction processing device.
6. The system of claim 1 , wherein simulating the key press input includes calling an Application Programming Interface (API) function for one or more digits included in the second token to emulate a user entering the key press input on a keyboard or a keypad device corresponding to the transaction processing device.
7. The system of claim 1 , wherein the first token is readable via a near-field communication (NFC) or by reading a microprocessor embedded in a chip card.
8. The system of claim 1 , wherein the second token includes an identifier portion that is uniquely identifiable to the at least one backend computing device.
9. A non-transitory machine-readable medium having stored thereon machine-readable instructions executable to cause a machine to perform operations comprising:
receiving a first token read from a token input device;
transmitting the first token over a network to at least one backend computing device;
receiving, from the at least one backend computing device, a second token that is different than the first token;
simulating input including a magnetic stripe input or a key press input; and
providing the simulated input to a transaction processing device.
10. The non-transitory machine-readable medium of claim 9 , wherein the token input device comprises a chip card or a mobile phone.
11. The non-transitory machine-readable medium of claim 9 , wherein simulating the magnetic stripe input includes generating a magnetic signal that transmits the second token to a magnetic stripe reader corresponding to the transaction processing device.
12. The non-transitory machine-readable medium of claim 9 , wherein simulating the key press input includes calling an Application Programming Interface (API) function for one or more digits included in the second token to emulate a user entering the key press input on a keyboard or a keypad device corresponding to the transaction processing device.
13. The non-transitory machine-readable medium of claim 9 , wherein the first token is readable via a near-field communication (NFC) or by reading a microprocessor embedded in a chip card.
14. The non-transitory machine-readable medium of claim 9 , wherein the second token includes an identifier portion that is uniquely identifiable to the at least one backend computing device.
15. A method comprising:
receiving a first token read from a token input device;
transmitting the first token over a network to at least one backend computing device;
receiving, from the at least one backend computing device, a second token that is different than the first token;
simulating input including a magnetic stripe input or a key press input; and
providing the simulated input to a transaction processing device.
16. The method of claim 15 , wherein the token input device comprises a chip card or a mobile phone.
17. The method of claim 15 , wherein simulating the magnetic stripe input includes generating a magnetic signal that transmits the second token to a magnetic stripe reader corresponding to the transaction processing device.
18. The method of claim 15 , wherein simulating the key press input includes calling an Application Programming Interface (API) function for one or more digits included in the second token to emulate a user entering the key press input on a keyboard or a keypad device corresponding to the transaction processing device.
19. The method of claim 15 , wherein the first token is readable via a near-field communication (NFC) or by reading a microprocessor embedded in a chip card.
20. The method of claim 15 , wherein the second token includes an identifier portion that is uniquely identifiable to the at least one backend computing device.
