Systems and methods active signature detection

1. A system for completing a transaction using an electronic transaction card, the system comprising:

a memory device storing instructions; and

a processor configured to execute the instructions to:

receive, from a user device executing a software application, a selection of a first account function associated with a financial transaction;

determine that the account function requires user verification;

detect, via a motion detection component of the electronic transaction card, a motion interrupt, wherein the detection of the motion interrupt causes the motion detection component to enter a full-power state associated with an increased sampling rate;

detect a motion pattern performed on the electronic transaction card by the user;

authenticate an identity of the user, by the electronic transaction card, based on the detected motion pattern;

complete, by the user device, the financial transaction; and

receive, from the user device, an indication that the financial transaction was completed, wherein the indication causes the motion detection component to enter a low-power state associated with a decreased sampling rate.

2. The system of claim 1 , wherein the motion pattern represents a shape, a series of taps on one or more edges of the electronic transaction card, or a signature.

3. The system of claim 2 , wherein the motion pattern is configured by the user.

4. The system of claim 1 , wherein the motion detection component comprises a multi-axis accelerometer.

5. The system of claim 1 , further comprising instructions to communicate with the user device via a near-field communication component.

6. The system of claim 5 , wherein the near-field communication component comprises a radio-frequency identification tag or a near-field communication antenna.

7. The system of claim 1 , further comprising instructions to authenticate the identity of the user based on a comparison between the detected motion pattern and a stored motion pattern.

8. The system of claim 1 , further comprising instructions to wake the electronic transaction card from a low-power state when the motion detection component detects a predetermined magnitude of acceleration, wherein the low-power state operates at lower power than a full power state of the electronic transaction card.

9. The system of claim 1 , further comprising instructions to receive, from the user device, a signal to wake the electronic transaction card from a low-power state, wherein the low-power state operates at lower power than a full power state of the electronic transaction card.

10. A method for completing a transaction using an electronic transaction card, the method comprising:

receiving, from a user device executing a software application, a selection of a first account function associated with a financial transaction;

determining that the account function requires user verification;

detecting, via a motion detection component of the electronic transaction card, a motion interrupt, wherein the detection of the motion interrupt causes the motion detection component to enter a full-power state associated with an increased sampling rate;

detecting a motion pattern performed on the electronic transaction card by the user;

authenticating an identity of the user, by the electronic transaction card, based on the detected motion pattern;

completing, by the user device, the financial transaction; and

receiving, from the user device, an indication that the financial transaction was completed, wherein the indication causes the motion detection component to enter a low-power state associated with a decreased sampling rate.

11. The method of claim 10 , wherein the motion pattern represents a shape, a series of taps on one or more edges of the electronic transaction card, or a signature.

12. The method of claim 11 , wherein the motion pattern is configured by the user.

13. The method of claim 10 , further comprising communicating with the user device via a near-field communication component.

14. The method of claim 13 , wherein the near-field communication component comprises a radio-frequency identification tag or a near-field communication antenna.

15. The method of claim 10 , further comprising authenticating the identity of the user based on a comparison between the detected motion pattern and a stored motion pattern.

16. The method of claim 10 , further comprising waking the electronic transaction card from a low-power state when the motion detection component detects a predetermined magnitude of acceleration, wherein the low-power state operates at lower power than a full power state of the electronic transaction card.

17. The method of claim 10 , further comprising receiving, from the user device, a signal to wake the electronic transaction card from a low-power state, wherein the low-power state operates at lower power than a full power state of the electronic transaction card.

18. The method of claim 10 , wherein authenticating the user further comprises:

collecting data from a motion detection component of the electronic transaction card; and

comparing the collected data with stored data corresponding to a preconfigured motion pattern.

19. A non-transitory computer-readable storage medium storing instructions for completing a transaction using an electronic transaction card, the instructions comprising:

receiving, from a user device executing a software application, a selection of a first account function associated with a financial transaction;

determining that the account function requires user verification;

detecting, via a motion detection component of the electronic transaction card, a motion interrupt, wherein the detection of the motion interrupt causes the motion detection component to enter a full-power state associated with an increased sampling rate;

detecting a motion pattern performed on the electronic transaction card by the user;

authenticating an identity of the user, by the electronic transaction card, based on the detected motion pattern;

completing, by the user device, the financial transaction; and

receiving, from the user device, an indication that the financial transaction was completed, wherein the indication causes the motion detection component to enter a low-power state associated with a decreased sampling rate.
