Could you imagine the stressful expression knowing that you have received fake dollar during a saving session at the bank counter? Counterfeiting is not a new game in the market, it has existed in human history starting from the ancient, where a ‘smart’ imitator cheat the general public to enjoy some short of profit by themselves.
Even though in past several decades, treasuries across the globe have been setting higher security standard to the country’s bank notes each and every year, but the counterfeiters seem always know how to produce the fake money and laundry the fake money into the the market.
You probably have known the security standard including watermarks, ink that never dries, holograms, and colors that canâ€™t be copied. But, the counterfeiters also keep on upgrading their printing technology each and every year.
In order to overcome the mass ‘stealing’ of a country’s bank note in the market, here comes the new technology that using thin-film transistors that are made out of gold, organic molecules, and aluminum oxide that designed to wrap on a legal bank note’s surface.
Owing to the invisble 3 volt invisible transistors and 100 different different organic on each side of the paper note, a merchants would be able to identify whether the bank note is legal or fake by putting it through a special designed sensor device.
Once the sensor could detect correspondent voltage, the bill will be defined as real, while without the responding voltage, a bank note is likely to be a fake currency note.
Building technology barrier to those counterfeiters is perhaps a good idea, but how long would it last? The smarter the police, the cleverer the thief, as long as human born with greed in their heart, would it just become another rat race or unending cycle of misery to prevent counterfeiting for governments around the world?
