Wireless communication beacon and gesture detection system

1. A secure transaction processing system comprising:

a wireless beacon;

a non-transitory memory; and

one or more hardware processors coupled to the non-transitory memory and the wireless beacon, and configured to read instructions from the non-transitory memory to cause the system to perform operations comprising:

associating a transaction at a point of sale system of a merchant with a transaction identifier;

in response to the associating, determining motion information based on changes in signal strength of a signal provided by a user device and detected by the wireless beacon at intervals;

detecting a first gesture of the user device based on the motion information; determining the first gesture of the user device corresponds with a trained gesture associated with the user device;

in response to the first gesture of the user device corresponding with the trained gesture, sending a broadcast that includes the transaction identifier using the wireless beacon to the user device;

providing transaction information of the transaction and the transaction identifier to a payment provider device over a network; and

receiving, from the payment provider device over the network, an indication that the transaction was completed using the transaction identifier.

2. The system of claim 1 , wherein the transaction identifier has an expiration.

3. The system of claim 2 , wherein the transaction associated with the transaction identifier is terminated when the transaction identifier expires.

4. The system of claim 1 , wherein the system dynamically changes a signal strength of the broadcast by the wireless beacon based on an estimated number of consumers.

5. The system of claim 1 , wherein a point of sales identifier is broadcasted with the transaction identifier using the wireless beacon.

6. The system of claim 1 , wherein the operations further comprise:

providing a receipt electronically to the user device for the completed transaction.

7. The system of claim 1 , wherein the operations further comprise:

dynamically changing a signal strength of the broadcast in response to receiving an indication of a number of user devices attempting to use the same transaction identifier.

8. The system of claim 1 , wherein the operations further comprise:

causing the user device to display information about the transaction on a display of the user device.

9. A method of performing a secure transaction, comprising:

associating, by a merchant system that includes a wireless beacon, a transaction at a point of sale system of a merchant with a transaction identifier;

in response to the associating, determining, by the merchant system, motion information based on changes in signal strength of a signal provided by a user device and detected by the wireless beacon at intervals;

detecting, by the merchant system, a first gesture of the user device based on the motion information;

determining, by the merchant system, the first gesture of the user device corresponds with a trained gesture associated with the user device;

in response to the first gesture of the user device corresponding with the trained gesture, sending, by the merchant system, a broadcast that includes the transaction identifier using the wireless beacon to the user device;

providing, by the merchant system, transaction information of the transaction and the transaction identifier to a payment provider device over a network; and

receiving, by the merchant system from the payment provider device over the network, an indication that the transaction was completed using the transaction identifier.

10. The method of claim 9 , further comprising:

terminating, by the merchant system, the transaction associated with the transaction identifier when the transaction identifier expires based on an expiration time associated with the transaction identifier.

11. The method of claim 9 , wherein a signal strength of the broadcast by the wireless beacon dynamically changes based on an estimated number of consumers.

12. The method of claim 9 , wherein a point of sales identifier is broadcasted with the transaction identifier using the wireless beacon.

13. The method of claim 9 , further comprising:

providing, by the merchant system, a receipt electronically to the user device for the completed transaction.

14. The method of claim 9 , further comprising:

dynamically changing, by the merchant system, a signal strength of the broadcast in response to receiving an indication of a number of user devices attempting to use the same transaction identifier.

15. A non-transitory machine-readable medium having stored thereon machine readable instructions executable to cause a machine to perform operations comprising:

associating a transaction at a point of sale system of a merchant with a transaction identifier;

in response to the associating, determining motion information based on changes in signal strength of a signal provided by a user device and detected by a wireless beacon at intervals;

detecting a first gesture of the user device based on the motion information;

determining the first gesture of the user device corresponds with a trained gesture associated with the user device;

in response to the first gesture of the user device corresponding with the trained gesture, sending a broadcast that includes the transaction identifier using the wireless beacon to the user device;

providing transaction information of the transaction and the transaction identifier to a payment provider device over a network; and

receiving, from the payment provider device over the network, an indication that the transaction was completed using the transaction identifier.

16. The non-transitory machine-readable medium of claim 15 , wherein the operations further comprise:

terminating the transaction associated with the transaction identifier when the transaction identifier expires based on an expiration time associated with the transaction identifier.

17. The non-transitory machine-readable medium of claim 15 , wherein a signal strength of the broadcast by the wireless beacon dynamically changes based on an estimated number of consumers.

18. The non-transitory machine-readable medium of claim 15 , wherein a point of sales identifier is broadcasted with the transaction identifier using the wireless beacon.

19. The non-transitory machine-readable medium of claim 15 , wherein the operations further comprise:

providing a receipt electronically to the user device for the completed transaction.

20. The non-transitory machine-readable medium of claim 15 , wherein the operations further comprise:

dynamically changing a signal strength of the broadcast in response to receiving an indication of a number of user devices attempting to use the same transaction identifier.
