1.  This product has two main functions.

(1) Verifying if the labels are properly deactivated or if the pieces of semihard material for deactivation perform well. This can effectively prevent false alarms caused by improperly deactivated labels.

(2) Verifying if there is any active label inside books or items. This can help to know if the labels are already placed inside books or items. Also, it helps to find out existed labels inside books when changing labels.

2. The verifier is very sensitive. It can detect labels with very low signal. Also, the detection height is high which makes verifying job more relaxed.
