Total-transfer - where an adhesive layer with a void messsage is left behind on the surface to show evidence of tampering. The adhesive layer may be cleaned off on some surfaces to allow reuse of the sealed object. The security label also exhibits the void message to prevent the reuse of the label. By leaving a void message on the surface, recipients will know that the object has been accessed and tampered with.

Non-transfer - where no void message or low traces of adhesive is left behind on the surface. Instead only the security label will exhibit the void message, preventing reuse of the label. With no void message left on the surface, the recipient must be aware there should be a security label, as a missing label or a different serial number is evidence of tampering. However, having no residue is convenient for when the sealed object is meant to be reused quickly - less time is spent cleaning off traces of adhesive.
