Payment vehicle with on and off function

1. A computing system comprising a transaction engine of a payment card network, the computing system configured to:

receive, from a user device of a user, a transmission including a rule to be applied to a payment vehicle of the user to limit which future transaction authorization requests are authorized by the computing system, the rule indicating whether to enable or disable the payment vehicle;

in response to receiving the transmission with the rule, update, by the transaction engine, logic of the payment card network associated with the payment vehicle to incorporate the rule, such that an updatable payment vehicle activation status of the logic is updated according to the rule to indicate whether the payment vehicle is enabled or disabled for transactions using the payment vehicle, the updated logic establishing additional security for the payment vehicle by automatically disabling the payment vehicle in response to transactions failing to satisfy the rule;

receive, from a merchant computing system of a merchant, a transaction authorization request;

apply, by the transaction engine, the updated logic to the transaction authorization request to determine that the transaction authorization request is for a transaction that does not satisfy the rule;

in response to the transaction engine determining that the transaction does not satisfy the rule, transmit to at least one of the merchant computing system and the user device an indication that the transaction authorization request from the merchant is not authorized; and

in response to the transaction engine determining that the transaction does not satisfy the rule, automatically cause the transaction to be denied.

2. The computing system of claim 1 , wherein the computing system is configured to receive an e-mail as the transmission with the rule.

3. The computing system of claim 1 , wherein the computing system is configured to receive an electronic text message as the transmission with the rule.

4. The computing system of claim 1 , wherein the computing system is further configured to:

receive, from the user device, a request for information regarding the logic associated with the payment vehicle; and

in response to receiving the request, provide information regarding the logic associated with the payment vehicle to the user device.

5. The computing system of claim 1 , wherein the rule in the transmission indicates the user wishes to disable the payment vehicle, and wherein the computing system is configured to update, in response to receiving the transmission with the rule, the logic associated with the payment vehicle such that the payment vehicle is disabled for subsequent transactions.

6. The computing system of claim 1 , wherein the rule in the transmission indicates the user wishes to disable the payment vehicle for transactions above an amount, and wherein the computing system is configured to update, in response to receiving the transmission with the rule, the logic associated with the payment vehicle such that subsequent transactions above the amount are not authorized by the computing system.

7. The computing system of claim 1 , wherein the rule in the transmission indicates the user wishes to disable the payment vehicle for transactions at a set of merchants, and wherein the computing system is configured to update, in response to receiving the transmission with the rule, the logic associated with the payment vehicle such that subsequent transactions at the set of merchants are not authorized by the computing system.

8. The computing system of claim 1 , wherein the rule in the transmission indicates the user wishes to disable the payment vehicle for transactions within a specified time interval, and wherein the computing system is configured to update, in response to receiving the transmission with the rule, the logic associated with the payment vehicle such that subsequent transactions within the specified time interval are not authorized by the computing system.

9. The computing system of claim 1 , wherein the computing system is further configured to, in response to updating the logic associated with the payment vehicle, provide the user with confirmation of updating the logic.

10. The computing system of claim 1 , wherein the computing system is further configured to:

receive, from a second merchant computing system of a second merchant, a second transaction authorization request;

apply the logic to the second transaction authorization request to determine that the second transaction authorization request is for a second transaction permitted by the rule; and

in response to the determining that the second transaction is permitted by the rule, transmit to at least one of the second merchant computing system and the user device a second indication that the second transaction is authorized.

11. A computer-implemented method, comprising:

receiving, by a computing system, from a user device of a user, a transmission including a rule to be applied to a payment vehicle of the user to limit which future transaction authorization requests are authorized by the computing system, the rule indicating whether to enable or disable the payment vehicle;

in response to receiving the transmission with the rule, updating, by a transaction engine of the computing system, logic of a payment card network associated with the payment vehicle to incorporate the rule, such that an updatable payment vehicle activation status of the logic is updated according to the rule to indicate whether the payment vehicle is enabled or disabled for transactions using the payment vehicle, the updated logic establishing additional security for the payment vehicle by automatically disabling the payment vehicle in response to transactions failing to satisfy the rule;

receiving, by the computing system, from a merchant computing system of a merchant, a transaction authorization request;

applying the updated logic to the transaction authorization request to determine, by the transaction engine of the computing system, that the transaction authorization request is for a transaction that does not satisfy the rule;

in response to the transaction engine determining that the transaction does not satisfy the rule, transmit to at least one of the merchant computing system and the user device an indication that the transaction authorization request from the merchant is not authorized; and

in response to the transaction engine determining that the transaction does not satisfy the rule, automatically cause the transaction to be denied.

12. The computer-implemented method of claim 11 , wherein the transmission comprises an e-mail.

13. The computer-implemented method of claim 11 , wherein the transmission comprises an electronic text message.

14. The computer-implemented method of claim 11 , further comprising:

receiving, by the computing system, from the user device, a request for information regarding the logic associated with the payment vehicle; and

in response to receiving the request, providing, by the computing system, to the user device, information regarding the logic associated with the payment vehicle.

15. The computer-implemented method of claim 11 , wherein the rule associated with the payment vehicle places the payment vehicle into a disabled state.

16. The computer-implemented method of claim 11 , wherein the rule associated with the payment vehicle disables the payment vehicle for transactions above an amount.

17. The computer-implemented method of claim 11 , wherein the rule associated with the payment vehicle disables the payment vehicle for transactions at a set of merchants.

18. The computer-implemented method of claim 11 , wherein the rule associated with the payment vehicle disables the payment vehicle for transactions occurring within a specified time interval.

19. The computer-implemented method of claim 11 , further comprising, in response to updating the logic associated with the payment vehicle, providing, by the computing system, the user with confirmation of updating the logic.

20. The computer-implemented method of claim 11 , further comprising:

receiving, by the computing system, from a second merchant computing system of a second merchant, a second transaction authorization request;

applying the logic to the second transaction authorization request to determine, by the computing system, that the second transaction authorization request is for a second transaction permitted by the rule; and

in response to the determining that the second transaction is permitted by the rule, transmitting to at least one of the second merchant computing system and the user device, by the computing system, a second indication that the second transaction authorized.
