The document describes Money Pad, a proposed replacement for paper currency using biometrics. Money Pad would use fingerprint recognition technology to provide secure electronic transactions. It would store a user's bank account information, including their fingerprint, to enable debit transactions. A fingerprint reader would verify the user's identity against the stored fingerprint before approving transactions from the Money Pad e-wallet. The document outlines how Money Pad could work, its technical implementation using biometrics, and its potential applications for secure e-commerce payments.

3. ABSTRACT
 Replaced paper currencies, electronically.
 Initiated debits and credits will become the dominant
payment modes, creating the potential for private money to
compete with government-issued currencies.
 Just as every thing is getting under the shadow of “e” today
we have paper currency being replaced by electronic
money or e-cash.
 The Money Pad introduced here uses the biometrics
technology for Finger Print recognition.
 Thus providing a form of security to the ever-lasting
transaction currency of the future “e-cash”

4. KEYWORD
MONEY PAD - A form of credit card or smart card similar to
floppy disk, which is introduced to provide, secure e-cash
transactions.
DIGITAL MONEY OR e-CASH - they refer to any of the various
methods that allow a person to purchase goods or services by
transmitting a number from one Computer to another.
BIOMETRICS TECHNOLOGY - Technology used to accurately
identify and verify an individual’s identity.
FINGER PRINT READER – A machine with read/write head
capable of reading the information stored in the Money Pad.

5. INTRODUCTION
 The 21st century will be paperless paper currency and checks
are gradually being substituted by smartcards, digital cash
and instant transfers of funds.
 It will hold Money Pad
containing digital cash and other
financial information, updated — perhaps automatically — by a
PDA with a satellite communication link.
 Biometrics Technology has made individual privacy even
more secure
 Money Pad recognises Finger Print’s of the user and decides
weather the user is a authorized or not.

6. PRESENT SYSTEM
(A)DEBIT CARD
(B)SMART CARD
They are payment devices that allows the consumer to make purchases
within guarantied limits as defined by the issuer of card.
Holds up to 8000 bytes of information
Disadvantages1- Instant clearing of funds is not possible .
2- User is always under the pressure of limits on purchase
defined by the issuer of the card and also every transaction involves
certain Charges

7. New Approach
To over come the above drawbacks of credit cards and smart cards
a medium of exchange to carry digital cash wherever man wants, which was
named as “Money Pad”.

8. Operations of money pad: Design of the system:-

9. Transaction using money pad
 A user wants to use the money pad he has to place his finger on the touch sensor
and then place it in a finger print reader. The reader will ask for bank code of the
database. Then he can enter into his e-bank, After the reader will access the
finger print.

10. Technical implementation of
money pad
The money pad uses the Biometric Technology as the
technique with which the security is provided. Biometric
Technology are used to accurately identify and verify an
individuals identity.
It generally believed that the pattern on each finger unique.

11. HOW A SENSOR WORKS ?
• A sensor reads the ridge pattern on the finger surface.
• Analog reading in the digital from through an analog
to digital converter.

12. How To Use Money Pad?
 New User :
1. Visit a nearby bank with e-banking facility.
2. Create an account with some balance.
3. Give necessary details along with finger prints.

14. CONCLUSION
For a digital currency system to attain widespread recognition
and use the following three requirements are necessary:
1. Instant clearing of funds
2. Elimination of payment risk
3. Secure transactions using strong encryption
Since the Money Pad aims to satisfy the above conditions there
is no doubt that in near future it will be widely recommended for
use.
