A sticker in biometric devices to kill germs

The biometric identification system which is now being increasingly used to establish an individual’s identity for Aadhaar cards, visa application or even attendance in offices has been found to be a potential source of germs. Studies have shown that the device which use technology to capture fingerprints harbor pathogens like staphylococcus aureus and E-Coli that easily spread through such contact points.

A startup in Chennai by the name Microgo has come up with a novel technology that works on a small patch-like sticker installed in these biometric systems which can sanitize fingers before or after the use of the device, thereby curbing the transfer of infections.

BARC scientist-turned entrepreneur Rachna Dave said the patches are made of a specialized silicon-based polymer which contains an alcohol or water-based sterilizing agent. They are stuck on the biometric fingerprint reading devices. When the user places his finger on the patch for reading, a solution immediately oozes out and works as a sanitizer killing germs.

Dave said the polymer is designed in such a way that the germs a user passes onto the surface of the device also gets killed in the process. She added that the patch can be used as much as 400 times. She informed that a sterilizing patch has also been designed for door knobs and handles that could be hotspots for infection transfer. Such patches could be used in the food industry, hospitals,schools, colleges and workplaces.
