Shopping container security system

A system to facilitate prevention of theft of an item in a shopping container, the system comprising:

• a controller attached or attachable to the shopping container;
• and
• at least one memory storing instructions that, when executed by the controller, cause the controller to perform operations comprising:
• receiving a first signal from a first transmitter upon entry of the shopping container into a first area within a store;
• after receiving the first signal, receiving a second signal from a second transmitter upon entry of the shopping container into a second area within the store;
• after receiving the second signal, receiving the first signal again without having received a third signal associated with a third area within the store, wherein the first signal, the second signal, and the third signal are different signals;
• and
• in response to receiving the first signal again without having received the third signal after receipt of the second signal, automatically switching from a normal mode to an anti-theft mode associated with the controller,
• wherein the system further comprises a third transmitter to transmit the third signal upon entry of the shopping container into the third area within the store, and a range of at least one of the first transmitter, the second transmitter, or the third transmitter is set to prevent the controller from receiving two or more of the first signal, the second signal, or the third signal simultaneously.

One or more non-transitory computer-readable storage media storing instructions that, when executed by at least one processor of a controller associated with a shopping container, cause the controller to perform operations comprising:

• receiving a first signal from a first transmitter upon entry of the shopping container into a first area within a store;
• after receiving the first signal, receiving a second signal from a second transmitter upon entry of the shopping container into a second area within the store;
• after receiving the second signal, receiving the first signal again without having received a third signal from a third transmitter associated with a third area within the store, the third transmitter provided to transmit the third signal upon entry of the shopping container into the third area within the store, wherein the first signal, the second signal, and the third signal are different signals;
• and
• in response to receiving the first signal again without having received the third signal after receipt of the second signal, automatically switching from a normal mode to an anti-theft mode associated with the controller,
• wherein a range of at least one of the first transmitter, the second transmitter, or the third transmitter is set to prevent the controller from receiving two or more of the first signal, the second signal, or the third signal simultaneously.
