According to one aspect of the present disclosure, a device and technique for impact detection includes a housing and switch circuitry having an omega-shaped switch element. A passive radio-frequency identification (RFID) module is coupled to the switch circuitry and is configured to detect a state of a circuit condition of the switch circuitry. A mass member is movable within the housing from a first position to a second position in response to receipt by the housing of an acceleration event. Movement of the mass member to the second position causes the mass member to move the switch element to change the state of the circuit condition of the switch circuitry.
