Traditional Footprinting Labels

Footprinting Labels

Our traditional footprinting labels (also known as VOID labels or checkerboard labels) are an off-the-shelf, easy-to-implement security solution that can help identify fraudulent tampering activity.

These Brady Defender™ labels produce a visible and irreversible footprint pattern if the seal has been altered. A “VOID” or checkerboard pattern will immediately appear across the seal upon any tampering attempt.

These standard footprinting labels are available as stock products, but in many cases can be used as a base material for adding customized overt or covert authentication features. 

This customized approach adds an extra layer of protection that is unique to your brand.
