A shopping cart wheel includes a braking apparatus, and electronics that control the braking apparatus in response to wireless signals. The wireless signals include low frequency electromagnetic signals within a low frequency band and high frequency signals within a high frequency band. The braking apparatus includes a moveable interposer and an interposer controller where the moveable interposer is moved between braking and non-breaking positions at least partially with magnetic force.
