1. An automated method of detecting an unauthorized exit of a shopping cart from a store, the method comprising: emitting, with a signal emitter, radio frequency signals into a checkout area of the store;detecting the radio frequency signals with a cart transceiver attached to a shopping cart, the cart transceiver comprising a wireless communication system and a controller;determining, based on the detected radio frequency signals, that the shopping cart is located in the checkout area; andautomatically determining, based on recent history information of the shopping cart, whether the shopping cart is authorized to exit the store,wherein the recent history information comprises an amount of time the shopping cart spent in the checkout area and the distance traveled by the shopping cart in the checkout area. 2. The method of claim 1, wherein the recent history information comprises the path and speed of the shopping cart. 3. The method of claim 1, wherein said automatically determining is performed by a monitoring system in bi-directional communication with the cart transceiver. 4. The method of claim 1, wherein said automatically determining is performed by the cart transceiver. 5. The method of claim 1, further comprising: determining, with the cart transceiver, a received signal strength indication (RSSI) value of the radio frequency signals;transmitting, with the cart transceiver, a response signal in response to detecting that the RSSI value exceeds a threshold; andreceiving the response signal with a monitoring system that is not attached to the cart. 6. The method of claim 1, further comprising automatically activating a brake of a wheel of the shopping cart in response to the shopping cart attempting to exit the store without the shopping cart having been determined to be authorized to exit the store. 7. The method of claim 1, further comprising determining whether a checkout station in the checkout area was active, and wherein said automatically determining is further based on whether the checkout station was active. 8. The method of claim 1, further comprising illuminating an indicator to provide a visual indication of a state of the shopping cart. 9. The method of claim 8, wherein the state comprises whether a wheel unit of the shopping cart is locked. 10. The method of claim 1, further comprising transmitting an exit authorized command in response to the shopping cart being determined to be authorized to exit the store. 11. The method of claim 1, further comprising: transmitting a lock command in response to the shopping cart being determined to be unauthorized to exit the store; andlocking a wheel of the shopping cart. 12. The method of claim 1, wherein the distance traveled by the shopping cart in the checkout area is determined by measuring the number of rotations of the wheel. 13. The method of claim 1, wherein the checkout area is a checkout lane or a checkout station. 14. The method of claim 1, further comprising determining movement of the cart. 15. A system for detecting unauthorized exits of shopping baskets from a store, the system comprising: a plurality of transceivers, each transceiver attached to a respective shopping basket, each transceiver including a wireless communication unit and a controller;a plurality of signal emitters, each signal emitter corresponding to a respective one of a plurality of checkout areas of the store, each signal emitter positioned relative to the respective checkout area to enable the transceivers to detect entry of the respective shopping baskets into the checkout area; anda monitoring unit that communicates bi-directionally with the transceivers; wherein the transceivers are configured to: use signals emitted by the signal emitters to detect entry of the corresponding shopping baskets into the checkout areas; andtransmit, to the monitoring unit, information indicative of whether the transceiver has detected entry into one of the checkout areas; andwherein the system is configured to: monitor a location history indicating that a particular one of the shopping baskets is in the general vicinity of the checkout area; anddetermine, based at least in part on the location history, whether the particular one of the shopping baskets is authorized to exit the store. 16. The system of claim 15, wherein the location history comprises the path of the shopping basket over time. 17. The system of claim 16, wherein the location history further comprises the speed of the shopping basket. 18. The system of claim 15, wherein the location history comprises an amount of time the shopping basket spent in the store since the previous entry. 19. The system of claim 15, wherein the location history comprises an amount of time the shopping basket spent in particular areas or departments of the store. 20. The system of claim 15, further comprising a plurality of shopping carts, each of the shopping carts comprising one of the shopping baskets.
