Abstract: To better protect collectible cards, a better tamper evident case is needed, one that counterfeiters cannot replicate. Disclosed is a collectible card case where each edge is physical unclonable function (“PUF”) material that counterfeiters cannot replicate. Further disclosed is a thermally sealed bag with an integrated PUF material where each bag is unique and unclonable, and a device for sealing and measuring the magnetic and optical properties of the PUF material. Finally, a reusable hard case is disclosed with features that allow for a one-time use PUF security clip.
