An electronic anti-theft label of a nickel-titanium alloy temperature memory wire includes a first housing, a second housing with a boss, a locking beam, a locking catch, a rotating device, a nickel-titanium alloy temperature memory wire, and an unlocking device. The second coil on the unlocking device generates, after being energized, a magnetic field around. The second coil serving as a sending end is placed in a third groove, so that the first coil is induced to generate electricity by using the electromagnetic induction principle, and the first coil serves as a receiving end. The sending end sends an electromagnetic signal to the external environment under the action of electric power, and the receiving end receives the electromagnetic signal and converts the electromagnetic signal into current. The nickel-titanium alloy temperature memory wire is energized and heated to contract to drive the rotating device to move.
