3. VISION
In the past few thousand years,
the way we pay has changed just
four times—from barter system
to coins, to paper money, to
plastic cards.
Now we’re on the brink of the
next big shift. We now want to
introduce the digital wallet, which
contains the virtual versions of
our existing plastic cards.

4. WHAT IS A DIGITAL WALLET
 A digital wallet allows a user to make an electronic payment with a
financial instrument (such as a credit card or digital cash), and hides
the low-level details of executing the payment protocol that is used to
make the payment.
 It authenticates the consumer through the use of digital certificates or
other encryption methods, stores and transfers value, and secure the
payment process from the consumer to the merchant.
 It can hold other than payments like Bank account details,Credit
cards,Gift coupons and reward certificates,Loyalty cards Offers.

5.  Thick, bulky, unmanageable physical wallet.
 Finding particular items is time consuming.
 Evocating a lost wallet is extremely hard.
 Managing multiple monetary and identification
implements is not easy. Monetary implements include
cash, debit and credit cards, and stored value cards
while identification includes national or state
identification cards and driver’s licenses.
 Reducing the chance of theft by having only one item to
manage.
THE NEED

6. COMPONENTS
 A digital wallet has a software and information component.
 The software provides security and encryption for the personal information
and for the actual transaction.
 Normally, digital wallets are stored on the client side and are easily self-
maintained and fully compatible with most e-commerce Web sites.
 A server-side digital wallet, also known as a thin wallet, is one that an
organization creates for and about you and maintains on its servers.
Server-side digital wallets are gaining popularity among major retailers due
to the security, efficiency, and added utility it provides to the end-user,
which increases their enjoyment of their overall purchase.
 The information component is basically a database of user-inputted
information. This information consists of your shipping address, billing
address, payment methods (including credit card numbers, expiry dates,
and security numbers), and other information.

7. TECHNOLOGY
 Secure Communication Medium
• New NFC (Near Field Communication) chips are already
appearing in smart phones which provide very close range, low
power, easy to setup up point-to-point communication.
• NFC acts as the communication medium for exchanging
monetary and identification information, such as credit card
numbers and receipts, with other devices.
 Fast Secure Authentication and Secure Tamper Proof
Storage
• Secure programmable chips in cell phones will allow the cell
phone to securely store both “digital cash” and the phone
owner’s monetary and identification implements.
• This assumes that the cell phone owner secures his digital
wallet with a good password. This chip will ensure that thieves
are unable to access the digital wallet embedded in the stolen
phone. Biometric scannersfor could also be integrated into cell
phones and used for quick and easy authentication.

8. OPERATION OF NFC
Near field communication is based on
inductive-coupling.
NFC works using magnetic induction
between two loop antennas located within
each other's 'near field’.
Operating frequency 13.56 MHz @ the
data rate 106 kbit/s to 424 kbit/s.
NFC use an initiator and a target; the
initiator actively generates an RF field that
can power a passive target.

9. How it works???
 Sender Mobile sends request to Transfer Money.
 System checks available balance in Sender’s A/C from
that particular Bank or wallet.
 It transfers money from senders A/C to receivers A/C.
 After a successful money transfer it sends a confirmation
notification (SMS/Email) to receiver.
 Money can be send and/or receive from PayPoints.

10. PAYMENT MODELS
 For point-of-sale transactions:-
 A NFC-compatible “reader pad or MobileNo. Or
QR code” can be deployed in retail stores.
 When payment is required, consumers place their
cell phone on/near the pad and all their valid
payment options appear on a display.
 They can then select the payment method they
plan to use (cash, specific credit card, etc.) for the
transaction.
 The pad transmits the transaction request to the
appropriate financial institutions using existing
banking protocols provided by NETS, Visa, Amex,
and MasterCard.
 The consumer can provide any necessary
signatures using a digital signature pad located
next to the reader pad.
 Once the transaction is verified and completed,
the receipt is automatically sent to the cell phone
and stored for future reference.

11.  For peer-to-peer cash exchange, use the phone’s NFC capability together
with an easy to use peer-to-peer cash application. Using the application, the
payer can enter how much cash he needs to send to the other person. The
payer then taps the cell phone of the payee and the cash is transferred
instantaneously using NFC. The recipient is then informed of the exact
amount transferred.

12. HOW TO SUPPORT CASH
TRANSFER
 Place cash in the digital wallet either by :
a) Topping-up the cash on device at specific top-up
machines which are integrated with existing automated
teller machines
b) Online by logging into bank’s online portal and
transferring cash into phone.
 Transferring that cash to a retailer or another digital
wallet by using NFC or any other method .

Manages information
about clients and groups
of clients of the wallet
including their user

and potentially other user

complexity of the other
components of the wallet,

17. DISADVANTAGES:
 System Outages: Information for digital wallets are stored on the cloud of
business servers; therefore, the risk of a system malfunction or shut down is
always present. As a result, businesses will not be able to process payments
or they will become increasingly slow due to high traffic in the servers.
 Security: Companies must ensure that their customers' information is
encrypted and well protected. One of the biggest concerns of adopting a
digital wallet application is "will my information be safe"? This is the hurdle that
companies must face and as a result, must develop security systems that are
as safe and full proof as possible to avoid potential security issues.
 Stake Holder Dynamics: Satisfying the business and strategic goals of
multiple stake holders such as banks, retailers, regulatory bodies, is difficult.
 Compelling user experience: A user-friendly wallet interface, easy to use
and intuitive is difficult to produce.

18. How it is being used right now?
There are many different companies offering E-Wallets.
Although each one is a little different, they all perform the
same basic tasks. Some of them are
 Paytm
 GOOGLE e-wallet
 PayPal
 ISIS
 Venmo
 Dwolla

19. Paytm
Paytm, owned by One97
Communications, is a digital
payments platform that allows
you to transfer cash into the
integrated wallet
via online banking, debit cards,
and credit cards, or even by
depositing cash via select banks
and partners

20. GOOGLE e-wallet
Google Wallet, currently
available for purchases in the
United States, lets you save all
your loyalty cards in once place.
You can also make payments
online and at any merchant that
has a card with credit attached to
it. If you need to send money to
someone, you can do so for free
as long as they're using Google
Wallet as well. Google Wallet
offers tap to pay for NFC-enabled
devices

21. ISIS
Isis is available to both AT&T and
Verizon customers and offers the
same tap to pay functionality
Android users currently enjoy
with NFC. The only catch? You'll
need to buy an accessory case to
make Isis work. After that you
can add all your payment cards,
including American Express
Serve and Chase bank cards, and
start tapping to pay at literally
thousands of merchants with tap
to pay terminals.

22. PAYPAL
PayPal is one of the most accepted
payment services on the planet.
Lots of physical merchants can
also let you pay with PayPal, no
actual credit card needed. The
PayPal app can use your location
to determine what merchants
around you let you pay with
PayPal. Once you're at the
checkout, just tell them you're
paying with PayPal instead of cash
or a card. You'll just have to enter
your mobile number and PIN and
you're good to go. PayPal just
deducts the funds from whatever
bank account or credit card you
have linked.
