Claim:
1. A shopping cart wheel comprising: a non-rotating component; a rotating component configured to rotate relative to the non-rotating component when the shopping cart wheel is in a non-braking configuration and configured not to rotate relative to the non-rotating component when the shopping cart wheel is in a braking configuration; a low frequency antenna; a high frequency antenna; a low frequency receiver electrically connected to the low frequency antenna and configured to receive one or more low frequency signals through the low frequency antenna; a high frequency receiver electrically connected to the high frequency antenna and configured to receive one or more high frequency wireless signals; a controller connected to the low frequency receiver and the high frequency receiver, the controller configured to place the shopping cart wheel in the braking configuration and the non-braking configuration in response to the one or more low frequency signals and the one or more high frequency signals; a wheel hub; and a clutch mechanism between the rotating component and the wheel hub, the clutch mechanism providing resistance between the wheel hub and the rotating component such that the wheel hub can rotate relative to the rotating component only when a force between the wheel hub and the rotating component exceeds the resistance.
