This portable device can disinfect both sides of banknotes, plastic currencies, receipts and sheet of paper in A4 and letter size. The multiple exchanges of banknotes, receipts and other such documents represent a high risk for users, as viruses and bacteria are transmitted on the surface. Conventional disinfection methods such as chemical disinfection or washing are not suitable for these materials. This disinfection device for currencies, cards and documents eliminates 99.9% of harmful microbes and thus prevents the spread of deadly pathogens.
The researchers said the device is recommended for use in public and private offices, banks, gas pumps, shops, and commercial establishments where cash / card transactions and the circulation of documents are part of routine activity. The design team introduced the essential features of the device to optimize its effectiveness using calculations and tests carried out at IIT Ropar, while ensuring the highest level of user safety through UVGI.
UV Germicidal Radiation (UVGI) can inactivate all types of bacteria and viruses tested to date, including coronaviruses. The UVGI light works in the UV-C spectrum, the effective wavelength spectrum for the germicidal effect.
This affordable device was created by Dr. Khushboo Rakha, Assistant Professor, Department of Metallurgy and Materials Technology, IIT Ropar, designed and developed as a prototype in collaboration with Humanity Works, Mumbai. A patent has been filed for the design.
During the drafting, Dr. Khushboo Rakha: “This simple device is the need of the hour to help organizations such as banks, post offices, authorities and private offices to work safely during this pandemic, as this machine (UVGI disinfectant) is short-wave ultraviolet (ultraviolet C- or UV -C) light to kill or inactivate microorganisms by destroying nucleic acids and destroying their DNA so that they can no longer multiply and infect. IIT Ropar is committed to the good of society and the nation as a whole in this time of crisis. ”
