A play object in combination with an identification tag, the identification tag being attachable to a play accessory for contacting and manipulating the play object, the play object and identification tag comprising: a body of the play object having an outer surface to be engaged by the play accessory upon a player using the play accessory, the body having an interior; a transceiver of the play object attached to the body and operable to emit an activation signal upon the body being contacted by the play accessory thereby positioning the transceiver in near field communication with the identification tag, and the transceiver configured to receive signals from the identification tag; the identification tag on the play accessory being a passive Near Field Communication tag operable to receive the activation signal from the transceiver and to emit in response thereto an identification signal to the transceiver, the identification signal comprising information on the player using the play accessory; and a data-collecting unit of the play object disposed in the interior of the body and operable during at least movement of the play object, the data-collecting unit comprising: an accelerometer unit measuring acceleration values of the play object along at least one translational degree of freedom; a gyroscope unit measuring rotation values of the play object about at least one rotational degree of freedom; a processor in communication with the transceiver, the accelerometer unit, and the gyroscope unit, the processor obtaining the acceleration values from the accelerometer unit, the rotation values from the gyroscope unit, and the identification signal from the transceiver, the processor wirelessly transmitting the acceleration values, the rotation values, and the identification signal; and a power source supplying electrical power to the transceiver, the accelerometer unit, the gyroscope unit, and the processor; wherein the transceiver is operable to emit the activation signal upon the accelerometer unit measuring an acceleration value exceeding a threshold value, and to not emit the activation signal when the acceleration value is less than the threshold value. a body of the play object having an outer surface to be engaged by the play accessory upon a player using the play accessory, the body having an interior;
