The document discusses e-wallets and near field communication (NFC) technology. E-wallets store digital payment information and have advantages over traditional cards like unlimited lifetime and storage of current balance. NFC allows contactless payment and data transfer between devices in close proximity by using magnetic field induction. NFC is supported on many mobile platforms and enables mobile payment apps like Google Wallet.

2. INTRODUCTION
What are Traditional cards??????

3. Advantages :
 Ease of Mobility
 Ease of use
Disadvantages:
 Easy duplication
 No memory to hold the current
balance
 Limited lifetime
 Limited acceptance
And the list goes on………….

4. About e-Wallet:
The electronic wallet (e-Wallet)
is just like a leather wallet as it
does the same, in terms of e-
cash.

5. Salient features of e-Wallet:
More than 40 years of Polarity reversal indicator
data retention is pre-built in our card.
Firewall encrypted Reusability of our card is
security logic unlimited.
Compatible with many Multiple card features are
supporting hardware. incorporated in the same
No separate card reader is card.
required to access our card External complexities are
less

6. Example for transaction:

7.  Refillable
 Infinitelifetime
 Current balance can be stored and read
 User authentication is provided
 Universal access
 Maximum possible cash
 Cannot be duplicated

8. Advantages of e-Wallet:
 Ease of use
 Accessibility and convenience
 Flexibility
 Safety and control

9. e-Wallet is supported on the following platforms:
 Windows® PC running Windows 7, Vista, or XP.
 Apple® iPhone®, iPad™ and iPod® touch, 3.0 and higher.
 RIM® BlackBerry® 4.2 and higher.
 Windows Mobile® 6 and Windows Mobile 6.1 and 6.5 Classic, Standard
(non-touch) and
 Professional (touch). Windows Mobile 6.5 devices are also known as
Windows phones.

11.  NFC or Near Field Communication is a short range high frequency wireless
communication technology.
 A radio communication is established by touching the two phones or keeping them in
a proximity of a few centimeters.
 NFC is mainly aimed for mobile or handheld devices.
 NFC is an extension of Radio frequency identification or RFID technology.
 RFID is mainly used for tracking and identification by sending radio waves.
 NFC devices can be used in contactless payment systems, similar to those currently
used in credit cards and electronic ticket smartcards, and allow mobile payment to
replace or supplement these systems.
 For example, Google Wallet allows consumers to store credit card and store loyalty
card information in a virtual wallet and then use an NFC-enabled device at terminals
that also accept MasterCard PayPass transactions

12.  In 2004, NFC Forum was formed by Nokia,
Philips, Sony,to set standards for NFC . Every
NFC enabled device will have “N-Mark”
trademark ,developed by NFC Forum.

13.  In 2006
First mobile phone( nokia 6131) with NFC
released by NOKIA.

14.  In 2010
First android phone SAMSUNG NEXUS S with
NFC support released.

15.  Near field communication is based on inductive-
coupling.
 NFC works using magnetic induction between two
loop antennas located within each other's 'near
field’.

16.  operating frequency 13.56 MHz.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.

18.  In Active mode, both devices with NFC chip
generates an electromagnetic field and exchange
data.

19.  In Passive mode, there is only one active device
and the other uses that field to exchange
information.

20.  Touch and Confirm
Applications such as mobile payment where the user
has to confirm the interaction by entering a password or
just accepting the transaction.

23.  High convenience to the user, because the data
exchange is done by bringing two mobiles
together.
 Reduces cost of electronic issuance .
 Secure communication.
 No special software.
 No manual configuration and settings.
 No search and pair procedure.

25.  In 2011, handset vendors released more than 40 NFC-enabled handsets.
 iOS mobile operating system does not support NFC.
 Google, on the other hand, includes NFC functionality in their Android mobile operating
system and provides a NFC payment service, Google Wallet.
 BlackBerry devices have also supported NFC using BlackBerry Tag on a number of
devices running BlackBerry OS 7.0 and greater.
 Mastercard has added further NFC support for PayPass for the Android and BlackBerry
platforms, enabling PayPass users to make payments using their Android or BlackBerry
smartphones.
 Microsoft added native NFC functionality in their mobile OS with Windows Phone 8, as
well as the Windows 8 operating system. Microsoft provides the "Wallet hub" in Windows
Phone 8 for NFC payment, and can integrate multiple NFC payment services within a
single application.

27.  QR Codes 2D barcode are Square bar codes, or QR codes are an easy way to inject info
into mobile phone. This makes it easy to create communication such visit a website or
copy useful text.
 QR codes have been around since they were invented in 1994. Originally used to track
products in warehouses, QR codes were designed to replace traditional (1D bar codes).
 Traditional bar codes just represent numbers, which can be looked up in a database and
translated into something meaningful. QR, or “Quick Response” bar codes were designed
to contain the meaningful info right in the bar code

28.  Online companies like PayPal, Amazon Payments and Google Wallet also have mobile
options
◦ Generally, the process is :
First Payment
 User registers, inputs their phone number, and the provider sends them an SMS with a
PIN
 User enters the received PIN, authenticating the number
 User inputs their credit card info or another payment method if necessary (not necessary if
the account has already been added) and validates payment
Subsequent payments
 The user re enters their PIN to authenticate and validates payment

29. Google Wallet
 Mobile pay is one of the
most innovative ways for
merchants to attract
customers.
 Although still in its
relative infancy, mobile
pay, which uses Google
Wallet for its transactions,
allows customers to
purchase items from
apples to zoo tickets at
brick and mortar stores by
using an Android app.

30.  Getting established
with Google Wallet is
simple, particularly for
merchants who
already accept
contactless payments;
otherwise a terminal
must be ISO 18092 or
14443 compliant.

31. It’s a free app for Android
phones.
Free coupons are available
from several sites.
Prepaid offers are also
available from Google
Offers Hub.
Both savings and checkout
are easier and faster for
the customer.

32. Google Wallet is
designed to work with all
retailers, networks, banks
and carriers.
Merchants attract a more
upscale customer base.
No network connection is
required for the
customer.
Cutting-edge security
measures provide the
ultimate safeguards for
the customer.
