Biometric finger printing devices are more commonly used in both the public and private sectors to record attendance. This system involves the physical contact between the skin and the surface of the device. When successive persons align their fingers on the device there's the prospect of the transmission mechanism of the microorganisms from one person to a different. Keeping in view, this study was carried out to assess hand hygiene practices in the context of our university (IIMTU) that uses biometric machines to monitor employee attendance. The study involved a total of 20 employees falling in the age group of 25-69 yrs. Employees participated in presented study were using public/self-mode of transport. Samples were collected from the surface of individual’s fingers before and after marking attendance using sterile cotton swab method. As a result, all individuals were found to carry microbial load before using biometric device. However, a significant increase in individual’s microbial load was reported after marking the attendance through biometric. This work clearly revealed that biometric devices significantly contribute towards transmission of microflora. The outcomes of this study indicate that there is an immense need of maintaining hand hygiene practices for individuals using such devices.
