VersaLok by Alpha High Theft Solutions is a great way to protect retail merchandise that is boxed. VersaLok is applied to the packaging with a removable "trace". If a shoplifter attempts to steal the merchandise or remove the VersaLok then the alarm sounds. Cashiers remove the VersaLok module at checkout to be reused. The trace stays on the packaging and goes out with the customer. The low cost, paper thin traces are replaceable.
