According to a report from Brazil, 5 doctors in a hospital in Sao Paulo were discovered to have bogus silicone digits and recorded the presence of some of their friends. It is estimated that there were around 300 bogus doctors present in the hospital whose attendance was being marked through such bogus methods.
The system also reveals that ordinary finger print scanners which don’t detect the pulse or don’t scan “below the skin level” are vulnerable to this type of attacks.
It is stated that the biometric scanners used and approved by the UIDAI in India are “Touch Scanners” which are susceptible to this kind of attack.
It is also known that even those scanners which try to read the finger print along with additional features such as temperature etc to detect if the print is from a live person can be fooled. More details are available here
