To provide timer equipment or the like, capable of appropriately performing athletic timing or the like while saving power.
A wireless tag (timer equipment) in a waiting mode is transferred, upon detecting arrival of a start point on a loop coil (T1), to a power-saved operation mode. The wireless tag is then transferred, upon detecting arrival of a clocking point onto the loop coil (T2), to a general operation mode. The wireless tag which is made communicable performs time communication operation (T3) and performs, upon detecting a polarity change point of electromagnetic field (T4), timing operation (T5) and polling operation (T7). When the polling operation is terminated, the wireless tag is transferred from the general operation mode to the power-saved operation mode.
