Physical shopping cart having features for use in customer checkout of items placed into the shopping cart
Physical shopping carts can have product detection systems and associate physical shopping carts with mobile computing devices (e.g., smartphones, tablet computing devices, smart watches, wearable computing devices). For example, physical shopping carts can be equipped with one or more product detection systems (e.g., scanners, sensors, cameras) that can electronically tally products that are placed in physical shopping carts. Mobile computing devices can be associated with and mounted on the physical shopping carts to provide a variety of enhanced shopping cart features not possible with conventional physical shopping carts, such as electronically tracking the contents of a shopping cart, checking-out from the mobile computing device (instead of at conventional check-out areas, such as point of sale terminals), and others.
1. A shopping cart for use in a retail environment, the shopping cart comprising:

the plurality of cameras includes, at least, a first camera and a second camera,
the first camera is attached to a first portion of the basket, and
the second camera is attached to a second portion of the basket that is different from the first portion of the basket.
4. The shopping cart of claim 3 , wherein the first portion is opposite the second portion with regard to a vertical plane bisecting the basket.
5. The shopping cart of claim 4 , wherein the first portion of the basket comprises a front of the basket and the second portion of the basket comprises a rear of the basket.
6. The shopping cart of claim 4 , wherein the first portion of the basket comprises a left side of the basket and the second portion of the basket comprises a right side of the basket.
7. The shopping cart of claim 3 , wherein:
the first camera is attached to the first portion of the basket with a first fixed orientation, and
the second camera is attached to the second portion of the basket with a second fixed orientation that is different from the first fixed orientation.
8. The shopping cart of claim 7 , wherein first camera and the second camera have intersecting and overlapping fields of view.
9. The shopping cart of claim 7 , wherein:
the first camera's first fixed orientation comprises the first camera being oriented toward a center region of the basket from a first vantage point provided by the first camera being attached to the first portion of the basket, and
the second camera's second fixed orientation comprises the second camera being oriented toward the center region of the basket from a second vantage point provided by the second camera being attached to the second portion of the basket.
10. The shopping cart of claim 1 , wherein the plurality of proximity sensors are attached to the basket adjacent the plurality of cameras.
11. The shopping cart of claim 1 , wherein:
the plurality of proximity sensors are configured to detect the items breaking one or more planes at or around the opening to the basket, and
the plurality of proximity sensors are configured to detect the items being placed into or removed out of the basket based on the items breaking the one or more planes.
12. The shopping cart of claim 1 , wherein the plurality of cameras are configured to only capture the images of the items in response to the proximity sensors detecting the items being placed into or removed out of the basket.
13. The shopping cart of claim 12 , wherein the controller is configured to identify the items in response to the plurality of cameras capturing the images.
14. The shopping cart of claim 1 , wherein the controller is configured to only identify the items based on the images captured by the plurality of cameras in response to the proximity sensors detecting the items being placed into or removed out of the basket.
15. The shopping cart of claim 1 , wherein
the proximity sensors are further configured to detect whether the items being placed into or removed out of the basket, and
the controller is further configured to update the virtual shopping cart based on whether the items are detected to be placed into or removed out of the basket.
16. The shopping cart of claim 1 , further comprising:
one or more lights that are configured to be selectively illuminated based on direction by the controller.
17. The shopping cart of claim 16 , wherein the controller is configured to illuminate the lights in a first color in response to positively identifying the items based on the images captured by the plurality of cameras, and to illuminate the lights in a second color in response to failing to identify the items based on the images captured by the plurality of cameras.
18. The shopping cart of claim 1 , further comprising:
a display device that is communicatively coupled to the controller and that is configured to present information about the virtual shopping cart to a user, wherein the display device is configured to be mounted at or near a handle for the shopping cart.
19. The shopping cart of claim 1 , wherein the camera and the proximity sensor pair is attached to a common circuit board that is provided in the common housing.
