How do you deactivate a magnetic security strip?

To deactivate a magnetic security strip, you typically need a specialized device called a deactivator, which emits a magnetic field to neutralize the strip. This process often occurs at the point of sale, where the cashier uses the deactivator after the purchase is completed. Some retailers may also use a handheld deactivator. Attempting to deactivate a strip without proper equipment can damage the item or cause the strip to malfunction.
