Fluorescent anti-counterfeiting, also known as ultraviolet anti-counterfeiting, is to combine special fluorescent ink on the label, so that the naked eye and touch can't find the position of serial number, text or pattern, and must be irradiated with fluorescent lamp, that is, ultraviolet lamp. Invisible fluorescent serial numbers are generally used by enterprises to prevent goods from escaping.

This technology uses ink with double invisible anti-counterfeiting performance to print fixed characters, patterns, numbers or flowing numbers on anti-counterfeiting labels. This technology is extremely hidden, and the hidden technology can't be found by the naked eye and touch. When identifying its authenticity, special testing instruments must be used. The fluidity of this technology can be used to prevent the smuggling of goods, and the effect of preventing the smuggling of goods can be achieved without using the anti-smuggling system. Moreover, this technology is invisible and not easy to be discovered and imitated. Invisible codes and bar codes can correspond (or not), tracking the behavior that can destroy labels and achieve the smuggling of goods.
