A void message is the hidden message which is left on the surface when the tape has been removed.
The void message is a key part of tamper evidence, the message or pattern, can be customised to suit your needs. This hidden message can be a pattern, barcode, words in different languages, even QR codes or logos.
Once the hidden message is revealed it is irreversible. This irreversible change provides evidence of unauthorised entry.
