During the COVID-19 pandemic, the virus's ability to spread via banknotes became even more of a concern to users.

In the fight against the COVID virus, some countries devise ways to clean the money. In Korea, people put money in the dryer of the washing machine. In Thailand, gas station staff use a racket with a long handle to receive and pay cash.

In Vietnam, at some sites where people are infected with COVID, money is processed by spraying alcohol, making the notes wet, uncomfortable for the user. Concerned about how to clean countless bacteria on money bills, even the COVID-19 virus, the owner of Thang Loi Mechanical Engineering Co., Ltd started to invent a microbial treatment machine for money bills.

After 10 times of repair, testing, and error-correcting, the money cleaning machine made by Thang Loi enterprises was finally introduced to publish.

Holding a stack of money to put into the machine and press the control button for the machine to operate, Mr. Ha Van Loi, director of Thang Loi Mechanical Engineering Co., Ltd. said that there are also a few types of disinfection machines on the global market today.
