2. Introduction
AIM : To create a biometric sensing machine which will help people in
paying their bills with the help of their finger print.

3. Literature Survey
1)Biometric Sensor:
• A biometric sensing machine is a security identification&
authentication device. This device uses automated method of
verifying the identity of a living person based on a
physiological or behavioral . This characteristics includes
fingerprint ,&voice recognition
• The study of automated identification, by use of physical or
behavioral traits.
• A fingerprint sensor is an electronic device used to capture a
digital image of the fingerprint pattern.

5. 2) Card Swiping Machine:
• An EDC machine (also known as a card swipe machine) is a
payment terminal provided by the bank on which the
merchant can swipe or dip cards to receive payments. Since
the card can be a debit card or a debit card, the machine is
also known as a credit card swipe machine or a debit card
swipe machine.

6. Idea Proposed
• Idea of the project is to make a card swiping machine which will
have a fingerprint sensor through which people could pay their
shopping bills.
• The fingerprint details will be stored in the database of the bank.
• Whenever someone applies his fingerprint on the sensor , he will be
automatically connected to his bank account and transaction will be
done.

7. Design
• The machine can be made by attaching the fingerprint sensor with
card swiping machine.

8. • This fingerprint scanner was developed by Arduino for lock systems.
In this system a transistor, an LCD chip, a resistors, lock and an
Arduino chip is used. This model is the easiest model that can be
used to make a biopay machine as this is not a complex system and
can be easily connected with the card swiping machine.

9. • Here the sensor chip can be the finger print sensor chip and this
could be easily connected to the Arduino system and therefore
biopay can be made.
• When the connection is made , the sensor will work and unlock the
lock in the system that will enable the machine to send the signal to
the bank that a transaction is being processed and the verification of
the transaction has been done by the user and he is willing to spend
his money from the account. After this, money will be deducted
from the account of the user.
• This is how we can make biopay using fingerprint sensor and a card
swiping machine.

10. Tools Used
• Card Swiping Machine
• Biometric Sensor
• Aadhar Card
• Switches

11. Implementation
• Firstly we would have to link our Aadhar card to the bank account so
that finger print details are accessed by the bank. This method of
payment will be added by the bank.
• To make a biopay we would first take a biometric sensor which has
finger print scanning technology. We would then take a credit/debit
card swiping machine and join the fingerprint sensor at the
magnetic chip sensor and make them compatible with each other.
As the machine accesses the database of the bank, the finger print
sensor will also be linked to the database. After the linking is
complete, the user will be able to use the finger print sensor which
will directly connect the person to his/her account.

12. Outcome
Advantages
• It is faster and easier method of payment.
• Shopping can be done at anytime ,even if a person is not carrying
anything with him.
• It is useful when credits card breaks or cracks.
• It is a very secure method of payment.
• Getting in stolen is not a problem.
• Getting it copied is not a problem.
• Being used by anyone else is not a problem.

13. Limitations
• If a person has different bank accounts ,then this could cause a
problem in payment.
Solution: After applying fingerprint an option will appear which
will provide himher with bank option from which heshe will
choose the bank through which he wants to pay.
• If by some reason ,the biometric sensor does not work or fails.
Solution: Bio pay will also provide card swiping system so that there is no issue
of payment.

14. Future Scope
• Biometric verification is gaining a lot of popularity among the public
security systems as well as in the commercial market. In our daily
life, we witness the use of biometric in so many places such as the
digital attendance system at offices, security checkpoints at
airports, wearable tech gadgets retrieving our biological
information, and even our national ID cards aka Aadhaar cards are
created using biometrics technology. In fact, this national ID
program holds the largest biometric database in the world.

15. • Biopay can become a revolution in the future and will make life
simpler.
• Biopay will enable people to pay their bills by just using their finger.
• This will also reduce security issues like losing of card as none would
be carried by anyone.
• The Future is here with Biopay.

16. Interdisciplinary Area
• We have combined IT technology with Electronics & Electrical
Engineering by combining a biometric sensor with a machine which
works on Database through which it accesses the accounts of the
user.

18. Conclusion
• This payment method could be a revolution & could simplify
payment on every aspect.
