Systems and methods for adjusting point-of-sale interfaces

1. A computer-implemented method for enabling a merchant to complete a transaction, the computer-implemented method comprising:

presenting, on a display of a POS device, a first interface associated with interaction with the merchant;

sensing a first change in a physical position of the POS device;

restricting access to a first set of functionalities of the first interface in response to sensing the first change in physical position of the POS device;

sensing a second change in the physical position of the POS device;

presenting, on the display of the POS device and in response to sensing the second change in the physical position of the POS device, the first interface associated with interaction with the merchant.

2. The computer-implemented method of claim 1 , wherein the first interface is configured to facilitate a creation of a line item by the merchant, the line item being associated with an item to be purchased by a customer.

3. The computer-implemented method of claim 1 , wherein the first set of functionalities comprises an ability to view or access private information including sales records, customer information, or merchant information.

4. The computer-implemented method of claim 1 , wherein changes in the physical position of the POS device comprise turning, rotating, or flipping the POS device.

5. The computer-implemented method of claim 1 , wherein changes in the physical position of the POS device are detected by a sensor.

6. The computer-implemented method of claim 5 , wherein the sensor indirectly detects the physical position of the POS device based on sensing whether or not the display is at a location.

7. The computer-implemented method of claim 5 , wherein the sensor provides an indication of change or adjustment to a POS application when change in the physical position of the POS device is detected.

8. The computer-implemented method of claim 7 , wherein the POS application is configured to adjust the first interface associated with interaction with the merchant to a second interface after receiving the indication of the first change in the physical position of the POS device from the sensor.

9. The computer-implemented method of claim 8 , wherein the second interface is configured to facilitate customer payment for an item to be purchased.

10. A device comprising:

a first interface associated with interaction with a merchant, wherein the first interface is presented on a display;

a sensor for sensing a physical position of the display;

a second interface associated with interaction with a customer, wherein the second interface is presented on the display in response to the sensor sensing a change in the physical position of the display; and

wherein the first interface has a first set of functionalities that is restricted in the second interface.

11. The device of claim 10 , wherein:

the first interface is configured to facilitate a creation of a line item by the merchant, the line item being associated with an item to be purchased by a customer; and

the second interface is configured to facilitate customer payment for the item.

12. The device of claim 10 , wherein:

the sensor senses a change in the physical position from a first position to a second position;

in the first position the display faces the merchant; and

in the second position the display faces a customer.

13. The device of claim 10 , wherein the second interface is a locked down version of the first interface.

14. The device of claim 10 , wherein the device is configured to adjust the physical position of the display by rotating the display.

15. The device of claim 10 , wherein the device is configured to adjust the physical position of the display by flipping the display.

16. The device of claim 10 , wherein the first set of functionalities is accessible only to the merchant.

17. A system comprising:

a display for a user interface, the user interface comprising a first interface and a second interface;

a sensor that detects an adjustment in a physical position of the display from a first position and from a second position;

at least one memory storing computer-executable instructions;

at least one processor configured to access the at least one memory and execute the computer-executable instructions to:

present, based on information from the sensor indicating the physical position is the first position, the first interface on the display; and

present, based on information from the sensor indicating the physical position is the second position, the second interface in the display; and

wherein the first interface is associated with interactions with a merchant and the second interface is associated with interactions with a customer.

18. The system of claim 17 , wherein:

the first interface is configured to facilitate a creation of a line item by the merchant, the line item being associated with an item to be purchased by a customer; and

the second interface is configured to facilitate customer payment for the item.

19. The system of claim 17 , wherein in the first position the display faces the merchant, and in the second position the display faces a customer.

20. The system of claim 19 , wherein the first interface is a merchant interface and the second interface is a locked down version of the first interface.

21. The system of claim 19 , wherein the system is configured to adjust the physical position of the display by rotating the display.

22. The system of claim 19 , wherein the system is configured to adjust the physical position of the display by flipping the display.
