1. Everything can be copied, including "Thumb Impressions".
2. Even humans & animals have been copied (cloned).
WHAT ABOUT THIS : (heee...heee... )
a) The bank should take DNA samples (as specimen) of their clients on their records, when opening of a bank account.
b) When ever a cheque is issued, the drawer should supply a drop of blood too with the cheque.
c) The bank would have the blood DNA checked with the specimen sample, from their in-house forensic dept. and then only clear the cheque.
d) However what happens if the drawer happens to donate his blood and the blood falls into wrong hands. One unit of blood full of DNA signatures will be sufficient to wipe out each bank account, his demat account and make him insolvent.
Please let the signature remain, in as it is condition, since the fraudesters and forgerers too have families.
BTW, most banks worldwide have banking transactions computerised and access'able, via internet, which is "literally" 100% safe. AS IT IS, NOTHING IN THIS WORLD IS 100% SAFE.
