The utility model relates to a be applied to measurement terminal row and prevent distorting secondary line radio frequency buckle belongs to intelligent buckle technical field, including radio frequency buckle, induction type electronics wafer card and scanner. The professional is behind the line of school in the measurement, withhold the radio -frequency card into the terminal row both ends, ifsomeone employs and falsify terminal row measurement secondary line privately, just must destroy the buckle could become flexible the screw, and the buckle produces destruction obvious, the designability to convenient relevant management Department collects evidence to the measurement secondary line of employing privately and falsifying, reaches the supervisory role to measurement secondary line.The measurement professional punch the card on the scanner through induction type electronics wafer card, obtains authority unblock or lock and all radio frequency buckles. Because terminal row both sides secondary line number volume is many, bring certain difficulty to the sexual periodicity inspection in the future of measurement professional, prevent through what the setting was buckled to theradio -frequency card that it marks the secondary line to falsify the label, can easily find measurement secondary line, provide work efficiency.
