Abstract

Described in detail herein are systems and methods for interacting with an interactive display using a shopping cart. A user navigate a shopping cart to a computing system including an interactive display and can actuate or press one or more push buttons associated with RFID tags integrated with the handle portion on a shopping cart to interact with the interactive display. A unique identifier can be associated with each RFID tag. A RFID reader disposed with respect to the computing system can detect the unique identifiers associated with the one or more detected RFID tags. The RFID reader can transmit the unique identifiers to the computing system. The computing system can execute the retrieved actions on the interactive display, based on the one or more buttons actuated or pushed and the correlated RFID tags.

Claims

1. A shopping cart system comprising:

a shopping cart including a frame having a handle portion, a basket supported by the frame, and a plurality of caster configured to support the frame;

an actuator disposed on the handle portion;

a plurality of RFID tags integrated with the handle portion, at least one of the plurality of RFID tags including a near field component and a far field component, wherein the near field component and the far field component are configured to be selectively coupled or decoupled in response to actuation of the actuator;

a plurality of RFID readers configured to communicate with the at least one of the RFID tags in response the at least one RFID tag being within range of the plurality of RFID readers and in response to the actuator being actuated to couple the near field component and far field component; and

a plurality of computing systems, each computing system being coupled to at least one of the plurality of RFID readers and including an interactive display, each of the plurality of the computing systems being programmed to;

receive communications from the at least one of the plurality of RFID tags via the at least one of the plurality of RFID readers operatively coupled thereto in response the at least one RFID tag being within range of the at least one of the plurality of RFID readers and in response to the actuator being actuated to couple the near field component and far field component;

determine whether to process the communications based on signal power of the radiofrequency communications received by the at least one of the plurality of RFID readers;

in response to determining that the signal power of the communications is below a threshold signal power, ignore the radiofrequency communications; and

in response to determining that the signal power of the radiofrequency communications is above a threshold power, identify data encoded in the communications and execute one or more actions on the interactive display in response to data.

2. The system in claim 1, wherein a database operatively coupled to the plurality of computing systems.

3. The system in claim 1, wherein the actuator includes a discrete push button.

4. The system in claim 1, wherein the near field component is a near field antenna and the far-field component is far-field antenna.

5. The system in claim 3, wherein the far-field antenna is tuned to a specified frequency.

6. The system in claim 1, wherein the plurality of the RFID tags are passive tags.

7. A method of interacting with a display associated with a first one of a plurality of computing systems via a shopping cart, each of the plurality of computing systems being coupled to at least one of a plurality of RFID readers, the shopping cart having a handle portion including an actuator for selectively coupling or decoupling a near field component and a far field component of at least one RFID tag in response to actuation of the actuator, the method comprising:

receiving, by the plurality of RFID readers, radiofrequency communications from the at least one RFID tag when the at least one RFID tag is within range of the plurality of RFID readers and in response to the actuator being actuated to couple the near field component the far field component;

receiving the radiofrequency communications at the plurality of computing systems from the plurality of RFID readers operatively coupled thereto;

determining, via a first one of the plurality of computing systems, whether to process the communications based on signal power of the radiofrequency communications received by the plurality of RFID readers;

ignoring the radiofrequency communications by the first one of the plurality of computing system in response the first one of the plurality of computing systems determining that the signal power of the radiofrequency communications is below a threshold signal power;

identifying, via the first one of the plurality of computing systems, data encoded in the communications in response to determining that the signal power of the radiofrequency communications is above a threshold power; and

executing one or more actions on the interactive display associated with the first one of the plurality of computing systems based on the data encoded in the radiofrequency communications.

8. The method in claim 7, wherein a database is operatively coupled to the plurality of computing systems.

9. The method in claim 7, wherein the actuator includes a discrete push button.

10. The method in claim 7, wherein the near field component is a near field antenna and the far-field component is far-field antenna.

11. The method in claim 10, wherein the far-field antenna is tuned to a specified frequency.

12. The method in claim 7, wherein the at least one RFID tag is a passive tag.
