Abstract
Example embodiments of information-shielding cards and systems and methods of fabricating the same are provided. An information-shielding card can comprising a substrate comprising a first layer, a second layer, a third layer, a chip embedded in the second layer, and a quick-response (QR) code formed on the second layer. The second layer can be disposed between the first layer and the third layer. The first layer can comprise a first material that is transparent when exposed to a non-visible light, the second layer can comprise a second material that is opaque when exposed to visible light and when exposed to non-visible light, and the third layer comprises a third material that is transparent when exposed to a non-visible light.
