Once inside the 230 thousand square meter area of the currency printing shop, an indescribable sense of excitement rises as you walk through the magnificent marble paved lobby, because right behind it is the currency printing shop, where you can see and smell the fresh taste of finely crafted banknotes flashing before your eyes.

A senior technician tells us: What looks like a simple banknote is actually full of several hidden devices, such as currency figurehead watermark, hand carved sculptures, magnetic security thread, low-vision feature, currency denominator printed in color-shifting ink, horizontal and vertical dual numbers, microprinting letters, etc. …. at least 10 different counterfeiting prevention security features. The most effective way to check a banknote´s authenticity is by observing the hair on the image. The hair on a real bill is very clear and vivid, with each strand completed in one single brushstroke. Such fineness cannot be copied on a counterfeit bill. Currency printing shops use the RS-232 signal to perform such precise image control. In addition, the number of banknotes printed and the important task of assigning a serial number for each banknote is also precisely controlled through the RS-232 signal!

In order to raise the hurdle for printing counterfeit currency, technicians at the currency printing shops go all out in making new technological breakthroughs, and at the same time request very unique equipment specifications. SUNIX not only provides state-of-the-art RS-232 serial cards, but also produces customized RS-232 transmission cables that are tailored made to meet the special requirements of currency printing shops. This type of exclusive service allows currency printing shop workers to feel assured and at ease.
