Wireless dongle facilitated mobile transactions

1. A system, comprising:

a signaling device connected to a merchant device at a location, wherein the signaling device provides a wireless communication protocol for a communication exchange between the merchant device and a mobile device of a user at the location within a wireless proximity range;

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:

detecting, via a hardware communication interface, the mobile device of the user using the communication exchange with the signaling device at the location, wherein the communication exchange occurs when the mobile device is within the wireless proximity range to the signaling device;

performing a user check-in for the user based on the detecting;

receiving a user identifier associated with the mobile device through the signaling device using the communication exchange;

determining an account of the user using the user identifier;

determining a history of past purchases for the user using the account;

transmitting, through the signaling device using the communication exchange, one or more promotional items to the mobile device based at least on the history of past purchases;

receiving a transaction processing request for a transaction from the mobile device at the location, wherein the transaction processing request is also received by the signaling device at the location from the mobile device over the communication exchange; and

causing a payment for the transaction using the account of the user when the mobile device is detected at the location using the communication exchange without requiring affirmative action by the user on the mobile device.

2. The system of claim 1 , wherein the operations further comprise: broadcasting, through the signaling device, one or more requests to perform the user check-in.

3. The system of claim 2 , wherein the one or more requests, when received by the mobile device, cause the mobile device to initiate a handshake request with the signaling device at an increased energy level.

4. The system of claim 1 , wherein the causing the payment comprises:

processing the payment from the account identified to the merchant device at the location.

5. The system of claim 1 , wherein the signaling device is self-powered.

6. The system of claim 1 , wherein prior to the transmitting the one or more promotion items, the operations further comprise:

selecting the one or more promotional items based on the location and the history of past purchases.

7. The system of claim 6 , wherein selecting the one or more promotional items are further based on

a merchandise for sale identified within a predefined proximity to the location.

8. A method, comprising:

operating a signaling device through a merchant device at a location, wherein the signaling device provides a wireless communication protocol for a communication exchange between the merchant device and a mobile device of a user at the location of a wireless proximity range;

detecting, via a hardware communication interface, the mobile device of the user using the communication exchange with the signaling device at the location, wherein the communication exchange occurs when the mobile device is within the wireless proximity range to the signaling device;

performing a user check-in for the user based on the detecting;

receiving a user identifier associated with the mobile device through the signaling device using the communication exchange;

determining an account of the user using the user identifier;

determining a history of past purchases for the user using the account;

transmitting, through the signaling device using the communication exchange, one or more promotional items to the mobile device based at least on the history of past purchases;

receiving a transaction processing request for a transaction from the mobile device at the location, wherein the transaction processing request is also received by the signaling device at the location from the mobile device over the communication exchange; and

causing a payment for the transaction using account of the user when the mobile device is detected at the location using the communication exchange without requiring affirmative action by the user on the mobile device.

9. The method of claim 8 , further comprising:

broadcasting, through the signaling device, one or more requests to perform the user check-in.

10. The method of claim 9 , wherein the one or more requests, when received by the mobile device, cause the mobile device to initiate a handshake request with the signaling device at an increased energy level.

11. The method of claim 8 , wherein the causing the payment comprises:

processing the payment from the account to the merchant device at the location.

12. The method of claim 11 , wherein the transaction processing request is received wirelessly from the mobile device through the signaling device.

13. The method of claim 8 , wherein prior to the transmitting the one or more promotion items, the method further comprises:

selecting the one or more promotional items based on the location and the history of past purchases.

14. The method of claim 13 , wherein the one or more promotional items is further based on

a merchandise for sale within a predefined proximity to the location.

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

providing a communication exchange between a merchant device and a mobile device of a user at a location through a signaling device at the location, wherein the signaling device is connected to the merchant device and provides a wireless communication protocol for the communication exchange over a wireless proximity range;

detecting, via a hardware communication interface, the mobile device of the user using the communication exchange with the signaling device at the location, wherein the communication exchange occurs when the mobile device is within the wireless proximity range to the signaling device;

performing a user check-in for the user based on the detecting;

receiving a user identifier associated with the mobile device through the signaling device using the communication exchange;

determining an account of the user using the user identifier;

determining a history of past purchases for the user using the account;

transmitting, through the signaling device using the communication exchange, one or more promotional items to the mobile device based at least on the history of past purchases;

receiving a transaction processing request for a transaction from the mobile device at the location, wherein the transaction processing request is also received by the signaling device at the location from the mobile device over the communication exchange; and

causing a payment for the transaction using account of the user when the mobile device is detected at the location using the communication exchange without requiring affirmative action by the user on the mobile device.

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

broadcasting, through the signaling device, one or more requests to perform the user check-in.

17. The non-transitory machine-readable medium of claim 16 , wherein the one or more requests, when received by the mobile device, cause the mobile device to initiate a handshake request with the signaling device at an increased energy level.

18. The non-transitory machine-readable medium of claim 15 , wherein the causing the payment comprises:

processing the payment from the account to the merchant device at the location.

19. The non-transitory machine-readable medium of claim 15 , wherein the transaction processing request is received wirelessly from the mobile device through the signaling device.

20. The non-transitory machine-readable medium of claim 15 , wherein prior to the transmitting the one or more promotional items the operations further comprise:

identifying a merchandise for sale within a predefined proximity to the location; and

selecting the one or more promotional items based on the merchandise and the history of past purchases.
