Counterfeited hang tags present a serious security threat. Fortunately, there are ways to prevent counterfeiting or at least make it extremely difficult to pull off. One of the most popular ways is adding a hologram to the tags. This can be in the form of holographic films that have 2D or 3D light refracting patterns or a unique micro-etched pattern. One may even use counterfeit deterrent Ink on the tags, which is a clear ink visible only upon illumination by a black light. Micro-print is also an efficient way of preventing counterfeiting. It involves the use of tiny-size text that can only be seen when magnified and cannot be reproduced by just any copier or printer. Additionally, there are some simpler ways also, such as using unique shapes, colors, or fonts, adding logos, etc.
