What is the blue strip on 100 dollar bill? This question often puzzles many people, especially those who are new to handling U.S. currency. The blue strip, also known as the security thread, is a crucial element in the design of the $100 bill, serving multiple purposes to ensure its authenticity and prevent counterfeiting. In this article, we will explore the significance of the blue strip and how it contributes to the security features of the currency.
The blue strip is woven into the paper during the manufacturing process and runs vertically down the length of the bill. It is made of a specialized material that contains tiny, metallic-like fibers. These fibers are embedded with a magnetic ink that can be detected by a magnetic reader, making it easier for banks and businesses to verify the authenticity of the bill.
One of the primary functions of the blue strip is to deter counterfeiters. The presence of the magnetic strip and the metallic fibers make it more difficult for individuals to replicate the bill accurately. Additionally, the blue strip is part of a series of security features that include a watermark, a color-shifting ink, and a raised printing technique, all of which contribute to the overall security of the currency.
The blue strip also contains a unique feature known as the “security thread,” which is visible when the bill is held up to the light. This thread is designed to appear as a series of letters or numbers, which can vary depending on the denomination of the bill. In the case of the $100 bill, the security thread features the number “100” in a variety of colors and orientations, making it difficult to replicate.
Another important aspect of the blue strip is its role in promoting accessibility. The magnetic strip can be read by individuals who are visually impaired, allowing them to easily identify the denomination of the bill. This feature is part of the United States Treasury’s ongoing efforts to make currency more accessible to all citizens.
In conclusion, the blue strip on the 100 dollar bill is a vital component of the currency’s security features. It not only serves as a deterrent to counterfeiters but also enhances accessibility for individuals with visual impairments. By understanding the significance of the blue strip, we can appreciate the meticulous attention to detail that goes into the production of U.S. currency.
