Scientists out of the National University of Singapore have found a method of utilizing nanohole technology to potentially prevent the counterfeiting of documents, credit cards, currency, and ID cards. The new technology was designed to incorporate over 34,000 nanoholes on an "ultra-capacity nano-photon sieve" surface. This surface would ensure that holograms could not be replicated by counterfeiting fraudsters.
Virtual information could be stored on the nanoholes, and holographic images would be displayed and retrieved with proper counterfeit detection devices. While this technology is still in the beginning phases, there is great hope that advancements in the field will help to prevent counterfeiting.
