Hologram stickers are self adhesive and tamper evident. They can be used on various substrates to help protect, secure and authenticate different items. Any tampering attempt may be obvious, as the stickers cannot be removed without destroying.

Hologram is a two or three dimensional photographic image produced by laser light.One of the most widely recognized hologram technology for anti-counterfeiting applications is the dot-matrix technique, where a design comprising of many tiny dots—which are too small to be seen by the naked eye (diameter usually bellow 100 µm) and each of which is a separate diffraction grating (a holo-pixel)
