Abstract
A system and a method are disclosed for tracking user activity with products in an environment. In an embodiment, a processor detects that a user has entered an environment, and responsively uniquely identifies the user. The processor determines that the user interacts with a product of a plurality of products within the environment, and responsively updates a profile of the user with indicia of the product. The processor determines whether the user is attempting to exit the environment, and, in response to determining that the user is attempting to exit the environment, prompts the user to confirm that the user intends to remove the product from the environment based on the updated profile. The processor receives input from the user confirming that the user intends to remove the product from the environment, and responsively further updates the profile based on the input.
