4. 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.
5. WHAT IS A DIGITAL WALLET?
A digital wallet is a software component that allows a user to make an electronic
payment with a financial instrument and hides the low-level details of executing
the payment protocol that is
used to make the payment.
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.

7. Server Side Electronic Wallet
A server side electronic wallet stores a customer information on the remote server
belonging to a particular merchant or wallet publisher
Client Side Electronic Wallet
A client side electronic wallet stores customer information on his/her own computer.
Many of the early electronic wallet were client side wallet that require users to download
the wallet software.
8. 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.
9. 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 phoneswill 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
scannerscould also be integrated into cell phones andused for quick
and easy authentication.
10. 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.
11. How it Works?
Sender Mobile sends request to Transfer Money.
System checks available balance in Sender’s A/C from that particular Bank.
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.
12. PAYMENT MODELS
For point-of-sale transactions:-
A NFC-compatible “reader pad” 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.
13. 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.
14. 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 intobank’s online portal and transferring cash into phone.
Transferring that cash to a retailer or another digital wallet by using NFC.

20. 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.
21. 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:
SQUARE Wallet
GOOGLE e-wallet
PayPal
ISIS
Venmo
Dwolla
22. SQUARE Wallet
Square Wallet lets you link a debit
or credit card to your Square
account and pay with it anywhere
Square payments are accepted. If
someone sends you a Square gift
card you can also store that inside
the Square Wallet app for use
whenever you're at that merchant.
For some places of business, you
can even choose items from
inventory and have your sale ready
before even getting to the cash
register.
23. 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
24. 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.
25. 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.
