Regardless of what kind of system you would use, you will be needing some auxilary equipments such as deactivators, double checkers or detachers.
Detachers have two main categories; Standard or Straight. Standard ones will be detaching normal tags but will not be much of a good at super locked ones.
Electrical or Manuel Detachers are only used for super tags, which use AM technology.
Other detachers as Stop Lock, Hook, Bottle Neck or Optics detachers are specialized detachers and only to be used in their own categories.
Deactivators, comes with sound option, are used for "killing" the soft tag attached on the goods you've sold and Double-Checker is for if the label "got killed" properly so that alarms won't go off. All the deactivators with sound also have light warning and they can be used as double checker, too.If no label will be used, devices with only having double-checker option would be a better choice since it is cheaper.
There is a needle detector in these categories too and it is used to check if any needle is left on the clothing after returning from tailoring.
