Proof-of-entry device and badge

摘要

A proof-of-use device made of a thick fibrous sheet such as paperboard has manually tearable perforation defining an invalidation component on one side of the perforation and a basic component on the other side of the perforated region. The basic component has a front surface adaptable to receiving a badge image. A flexible region formed in the basic component defines a hinge along which the basic component is bendable over on itself. An attaching component is applied to at least one selected region of the basic component. Depending on configuration the attaching component may be on the front or back of the basic component. The attaching component and the hinge make the basic component attachable for wearing to display the badge image.
