Abstract: Systems and methods for operating a Security Tag (“ST”). The methods comprise: capturing a first Tack End (“TE”) of a Tack Assembly (“TA”) by a first Securement Mechanism (“SM”) disposed in the ST's body; removing a Tack Head (“TH”) from TA so as to expose a second TE that is opposed to the first TE; placing TH on the second TE; and capturing the second TE by a second SM disposed in TH. Alternatively/additionally, the methods comprise: retracting a tack into a TH of TA; depressing TH so as to cause telescoping concentric parts to slide into each other; causing a free end of the tack to travel out of TH while the telescoping concentric parts are being slid into each other; inserting the free end of the tack into ST's body; and capturing the free end of the tack by SM disposed in ST's body.
