Why is there a metal thread in currency notes? 75 years ago, threading started in England, know the history!

All of you must have seen a special thread in print currency ie notes. This thread is not ordinary but made in a special way. It also plays the most important role in checking the authenticity of any note. This thread is made of metal and came to be used as a safety standard. You must have also seen some codes on the thread inside the 500 and 2000 rupee notes.

Actually, the idea of ​​putting the metal thread in notes came in 1848 in England. It was also patented. However, it could be implemented only after about 100 years. This ploy was also used to stop the printing of fake notes. The process of inserting a special thread between the notes is now completing 75 years.

According to "The International Bank Note Society" i.e. IBNS, "Bank of England" did the work of putting the metal band in the middle of note currency in 1948 for the first time in the world. 

When the note was held against the light, a black line was visible in the middle. By doing this it was believed that even if the criminals could counterfeit the notes, they would not be able to make the metal thread. However, later people were fooled by making only a simple black line inside the fake note.

In 1984, the Bank of England introduced broken metal threads on the £20 note. It was thought that since this metal thread is in many pieces, the criminals would not be able to make it. However, this experiment also failed. Counterfeiters started using broken aluminum threads.

However, the government has left no stone unturned in creating safeguards against counterfeiters. Later, instead of metal, plastic strips were also used. In the 1990s, central banks belonging to the governments of many countries used plastic threads as security codes in bank notes. Along with this, some printed words were also used on the thread. Which has not yet been copied.

In October 2000, the Reserve Bank of India issued a 1000-rupee note in India, using a thread reading INDIA, 1000, and RBI in Hindi. Now the 2000 note has a metal strip on which RBI is written in English and India is written in Hindi. All this is written in reverse. The 500 and 100 rupee notes also use a similar security feature.

This method is also used on 5, 10, 20, and 50 rupee notes. This thread is on the left side of Gandhiji's portrait. Earlier, the metal strip used by the Reserve Bank did not have anything written on it. Generally, the metal strip used by banks is very thin.

The use of metal bands on currency notes in India started very late. You will see this band in two colors on Indian currency notes. Its color is golden and it shines. The E strip on the 2000 and 500 notes is green. However, the color of this strip is red on the notes of some countries. The metal strip used on the higher denomination notes of India is silver.

This strip of metal is pressed inside the notes using a special technique. You will see these bands shining when you hold them against the light.

Usually only a few companies in the world manufacture this type of metal strip. India imports such strips for its currency.
