About Security Tag Remover

Many people wonder how to remove the security tag. In fact, you only need to pull the beads up, lowering the tension on the nail and making it easy to remove, therefore, security tag remover have emerged.

For security tag remover, magnetic field will be gathered in a specified area through special designs for the whole magnetic circuit, and nail can be removed rely on enough attractive force between beads and security tag remover.

Different security tag has the different requirement of the magnetic field, and SDM team skilled in design and optimize the magnetic circuit by FEM simulation software, then provide the suitable solution to customers.
