Back in 1996, the United States Treasury introduced an important security feature on its 100 dollar bills: the security strip. This addition was a response to the increasing problem of counterfeiting and aimed to provide a reliable and robust method of authentication. Since then, the security strip has become a crucial component of the bill, ensuring its authenticity and integrity.
The introduction of the security strip marked a significant milestone in the evolution of currency security measures. Prior to its implementation, counterfeiters had been able to replicate the appearance of genuine bills relatively easily, making it essential for the government to enhance the existing security features. The solution came in the form of a polyester strip embedded within the paper of the 100 dollar bill.
The **security strip**, also known as the **embedded security thread**, is a thin, vertical strip that runs along the left-hand side of the bill when looking at the front. It is approximately 2 millimeters wide and is visible when held up to light or examined closely. The strip is woven into the paper and is an integral part of the bill, making it difficult to counterfeit.
