this research is to provide a trustable path for card swiping transactions by
using the latest Biometric Authentication Techniques to the already in use PIN
authentication. The present Card swiping machines should be replaced with
machines with an added Biometric Scanner. Every card is registered with the
owner’s fingerprint only. The transaction happens successfully only after the
card user enters the card PIN correctly and after the card accepts the
registered fingerprint of the user.

the registration process of the card or if the owner does it manually?

first, PIN authentication or Biometric Authentication?

·       How much time does it take for the
whole transaction to complete successfully and what are the better ways to
reduce the time taken?

nearly impossible. Individuals will be more inclined to go cashless with a
trusted mode of card swiping payments.

the Card swiping machine.
