UV lamp illuminating security banknote with invisible inks and blockchain hash network for anti-counterfeit protection.
Anti-counterfeit printing combines covert inks that respond to ultraviolet (UV) or infrared (IR) light with serialized codes recorded on a blockchain ledger. The ink binds authentication to the physical item, while the ledger stores one 256-bit cryptographic hash per serial that exposes altered records. The ledger alone cannot confirm that […]

UV LED is one of the finest technologies designed to generate intense light, albeit with minimal power consumption. Ideally, especially in the printing business, they can emit significantly little heat while enjoying a longer lifetime. LEDs are beginning to replace traditional hot, power-hungry, and short-lived metal halide (mercury vapor) lamps […]
