Various embodiments of a system for tracking and/or controlling wheeled vehicles (such as shopping carts), are described. In some embodiments, the system includes an RFID tag on the cart and an RFID reader device external to the cart. The tag can receive an interrogation signal from the reader and reply with a response signal. In various embodiments, the reader or a central control unit can perform various calculations based on the response signal, such as generating a received signal strength indication (RSSI) value. In some embodiments, based on the RSSI value or otherwise, the reader can send a command signal to the tag to take an action, such as to engage a brake mechanism.
