The data would be transmitted as well as received on the 125kHz bandwidth. This is because they are un-powered, and they would have a limited transmission range – anywhere from 1 to 15 centimetres. Certain materials can be penetrated by these radio transmissions like the plastic surrounding the chip built into a car key.
