Systems and methods for secure transaction approval

1. A server, comprising:

a processor; and

a memory,

wherein the processor is configured to:

receive, from a client device, a transaction request specifying a time period for receipt of a transaction approval, the transaction request being received following a transaction lockdown request transmitted to the client device; and

upon receipt of a notification of the transaction approval:

transmit an allowance response if the notification is received within the time period, and

transmit a disallowance response if the notification is received after the time period.

2. The server of claim 1 , wherein the processor is further configured to, prior to transmission of the allowance response, confirm that a transaction associated with the transaction request is associated with an appropriate transaction type provided in the transaction request.

3. The server of claim 2 , wherein the processor is further configured to transmit the disallowance response if the transaction is not associated with the appropriate transaction type.

4. The server of claim 1 , wherein the processor is further configured to modify the time period based on at least one selected from a group of a transaction amount, a transaction location and a user account data records.

5. The server of claim 4 , wherein the transaction location corresponds to a location of the client device initiating the transaction.

6. The server of claim 1 , wherein, if the notification is received after the time period, the processor is further configured to reject all transactions.

7. A method, comprising:

receiving, by a client application comprising instructions for execution on a client device, a transaction lockdown request from an authentication server;

sending, by the client application, a transaction approval request in response to a transaction notification received following the transaction lockdown request;

receiving, by the client application, a tap from a transmitting device on the client device;

sending, by the client application, a transaction pre-approval to the authentication server;

receiving, by the client application if the transaction pre-approval is received by the authentication server within a time period, an allowance response from the authentication server; and

receiving, by the client application if the transaction pre-approval is received by the authentication server after the time period, a disallowance response from the authentication server when the transaction pre-approval is received by the authentication server after the time period.

8. The method of claim 7 , wherein the transaction approval request comprises a data value for the time period.

9. The method of claim 8 , further comprising disabling, by the client application, a function of the transmitting device after receiving the transaction lockdown request.

10. The method of claim 9 , further comprising enabling, by the client application, a function of the transmitting device after receiving the allowance response.

11. The method of claim 10 , wherein the transmitting device comprises a contactless card.

12. The method of claim 7 , further comprising, prior to sending, by the client application, the transaction approval request in response to the transaction notification:

receiving, by the client application, a pre-approval option selection for a pre-approved transaction;

sending, by the client application, a request to the authentication server to permit a transaction pre-approval within the time period;

receiving, by the client application, the transaction notification from the authentication server; and

matching, by the client application, the transaction notification to a pre-approved transaction.

13. The method of claim 12 , wherein matching the transaction notification to the pre-approved transaction includes matching a merchant and an amount associated with the transaction.

14. The method of claim 12 , wherein:

the pre-approval option selection includes a transaction type, and

the method further comprises modifying, by the application, the time period based on the transaction type.

15. The method of claim 7 , further comprising modifying, by the client application, the time period based on at least one selected from the group of a transaction amount and a transaction location.

16. The method of claim 7 , further comprising modifying, by the client application, the time period based on at least one selected from the group of a merchant, an account type, account information, and account history.

17. A method, comprising:

transmitting, by an authentication server, a transaction lockdown request to a transmitting device, the transaction lockdown request being transmitted to the transmitting device via a client application comprising instructions for execution on a client device;

receiving, by the authentication server, a transaction approval request from the client device, the transaction approval request comprising an appropriate transaction type and a data value specifying a time period for receipt of a transaction approval;

receiving, by the authentication server, the transaction approval;

confirming, by the authentication server, that a transaction associated with the transaction approval request corresponds to the appropriate transaction type;

transmitting, by the authentication server, an allowance response if the transaction approval is received within the time period; and

transmitting, by the authentication server, a disallowance response if the transaction approval is received after the time period.

18. The method of claim 17 , wherein the lockdown request comprises an instruction to disable a function of the transmitting device.

19. The method of claim 18 , wherein the allowance response is configured to enable the function of the transmitting device.

20. The method of claim 18 , wherein the appropriate transaction type corresponds to a card-present transaction type or a card-not-present transaction type.
