Systems (100) and methods (800) for operating a pin tag. The methods comprise: moving a first structure with a flange in a first direction; and sliding a chamfered surface of the flange against a chamfered surface of a second structure so as to move the second structure in a second direction away from the first structure. The second direction is angled relative to (e.g., perpendicular to) the first direction. Thereafter, the second structure is resiliently biased towards the first structure when the first structure has moved a certain distance in the first direction to a first position. The first structure is retained at the first position through an engagement of the second structure with the flange which is resiliently biased towards to the second structure in a third direction opposed from the first direction.
