Initialization phase


Before providing NFC
-
based service, constructing an NFC
mobile commerce environment is needed. There are four
critical components:


back
-
end services



responsible for all information exchange during the commerce process.


Generic terminal service(GTA)


The application is responsible for retrieving information from back
-
end service


Function tags


Function tags trigger the GTA to communicate with back
-
end service or
activate the connection .



Four types of tag are defined in the NMC Model:


First
-
time Tag (FT), Product Tag (PT), Coupon Tag (CT), and Service Tag (ST).


NFC
-
enabled handsets


Before using the NFC
-
based service, GTA has to be loaded in the NFC
-
enable
handset in advance

Ordering phase


After initialization, the customer can start to use NFC
-
enabled handset to download the catalog and place the order


Merchant's catalog

1:tapping the handset on the PT.

2:The handset will retrieve the content of the PT and launches the
corresponding GTA automatically

3:GTA will download the corresponding catalog from the back
-
end
server according to the content stored in the PT

4:After that, GTA can display the product information such as
descriptions, images, videos, and product dependent options.

Shipping/Collection phase


customers can choose how they receive their products or
services.


For physical products, they can choose a place to ship or to collect,
such like their home address or exit number of shopping mall.


For virtual products, such as on line music or video game, it should
be transferred virtually to a particular storage device by email or short
message.

Loyalty management phase


Loyalty program is designed to attract a customer to
purchase again.


Receiving coupons Customers can receive coupons by tapping a
CT which accounts for downloading a coupon.


Coupon sharing mechanism With NFC
-
enable handsets, customers
can share their coupons with others more easily.

11

RFID Lab, Dept. IECS, FCU

Service phase


If customers require assistance for any problem, they can just
tap the ST by the handset. The service request will be
addressed, and the corresponding service can be delivered
as soon as possible.

Order

15

RFID Lab, Dept. IECS, FCU

Payment


E
-
Wallet

1:a consumer order and determines to pay by e
-
wallet,

2:the application will activate the connection and transfer the order
information to the back
-
end service by 3G or

GPRS.

3:the back
-
end authentication will request the application to check the
e
-
wallet and auto debit if the balance is sufficient.


Credit Card

1:the customer decides to pay by credit card

2:The GTA will upload the order information to back
-
end service by3G or
GPRS, and write the order number into SE.

3:the order information will be recognized by external readers.



16

Shipping/collection



the bill is paid, the consumer will be asked to choose Dine
-
in
or take
-
away.


Dine
-
in

1:customer chooses to dine
-
in, he/she can use the handset to tap the seat
tag which is embedded on the table.

2:GTA will transfer the seat number to back
-
end service

3:waiter can use this information to deliver the service.


Take
-
away

1:After receiving the customer's order, the back
-
end service will transfer
the order information to the screen/printer in the kitchen.

2:For take
-
away, consumers just wait for the SMS which will inform
them where to take out their meal.

Loyalty&Service


Loyalty


If the consumer completes the ordering process, the back
-
end
service will send a restaurant coupon to the handset directly.


Or customers may just tap the handset on CT to download the
coupon for a special discount.


The customer may share coupons with others, so that more than
one customer benefits from the coupon discount.


Service


Consumers simply tap these tags with their handsets and then select
the service, their selection will send to the backend service.

Conclusion


we propose a generic model for NFC
-
based mobile
commerce.



we implement the service in a normal restaurant in order
to verify the feasibility and flexibility of the model.




According to the experience, service providers can built up
a feasible NFC
-
based solution to satisfy several mobile
commerce scenarios

THE DUAL APPROACH OF STOLPAN


StoLPaN

(Store Logistics and Payment with NFC)aims to
establish a secure, interoperable operating environment for
third party applications delivered into Secure Elements (SEs)
in an NFC
-
enabled mobile handset.



the following deliverables have been defined for the project: a
set of commercial and technical frameworks for the delivery,
use, update and removal of secure NFC
-
enabled applications



The dual approach to develop the technical and commercial
environment simultaneously will also help to harmonize the interests
of diverse stakeholders and to promote the deployment of NFC
-
enabled mobile applications in many diverse markets

NFC TECHNOLOGY AND THE BASIC
CHALLENGES OF THE NFC ECOSYSTEM


NFC is a standard
-
based, short
-
range wireless
communication technology at 13.56 MHz radio frequency
that enables simple and safe two
-
way interactions among
electronic devices.



One of the key directions of development is to define an
environment that supports NFC services portfolio
management.



when defining the NFC
-
based services and applications,
only a part of the problems are technology related, and even
those have business process implications usually.

FUNCTIONAL SCHEME OF NFC
-
BASED
MOBILE SERVICES(1/2)


User,


is the person who selects the application/service and can initiate the
request for post issuance and personalization.


the SE Issuer


has control over the SE. Control means the right to decide how the SE’s
storage capacity is used.


the Service Provider.


is the actor who wishes to deploy or manage a service application or
data element on the SE

DIVERSE INTERESTS AND POSSIBLE

CONFLICTS
BETWEEN MAJOR

STAKEHOLDERS(1/2)


The MNOs(Mobile Network Operators)


have the natural advantage that they control the only generally
available download facility. Moreover, they also have the space on
their SIM cards, which could also be utilized for storing third party
secure applications. Controlling the download and hosting the
applications as well
-

two services that can be charged for



service providers


would prefer a solution where they can independently arrange for
the application download, and where the application would be hosted in
a neutral space in the handset. This could be a second chip, which is
either embedded in the device or an SD card that can be used in various
devices, or under certain operating and security conditions even a SIM
card

DIVERSE INTERESTS AND POSSIBLE

CONFLICTS
BETWEEN MAJOR

STAKEHOLDERS(2/2)


whose interests must be harmonized, otherwise either
conflicting, not interoperable solutions will gain market
acceptance, or the technology itself will not be able to
proliferate

TECHNOLOGICAL DEVELOPMENT AND
BUSINESS PROCESS

ANALYSIS(1/2)


The first major research track of the
StoLPan

project was to
establish an open platform for the delivery, use, update and
removal of secure NFC
-
enabled applications on mobile
devices.


The main functions of the technical platform are



technical transparency


single platform;



remote communication, information provision;



dynamic management of multi
-
application SEs;



application management;



application interoperability.

TECHNOLOGICAL DEVELOPMENT AND
BUSINESS PROCESS

ANALYSIS(2/2)


At the same time, following the basic concept of simultaneous
development and cooperating with service providers, MNOs
and other key players in the value chain, the
StoLPaN

consortium identifies and analyses the applications and use
cases that the open NFC platform will enable.


The process involves:


Evaluating how NFC affects the existing value chain for the issuance of
payment cards, tickets and other services;


Identifying the business requirements and flow of funds within and
among the key players;


Verifying the commercial dependencies and distribution of risk
between key stakeholders.


29

RFID Lab, Dept. IECS, FCU

The transparent technology platform and
common methodology


From the technical aspect


hiding diversity of handsets and applications;


specification of general minimum requirements;


introducing standards;


simpler development, applications distribution and applications management.


From the commercial aspect


revenue generation for key stake holders;


testing new use cases;


performing user studies;


validating existing solutions;


introducing new value
-
added functions;


identification of issues that deteriorate economics of services;


identification of issues that hinder penetration of the technology, or individual
services.

CONCLUSIONS AND FURTHER
DEVELOPMENT DIRECTIONS


NFC
-
enabled mobile services have proved is that
technology and standardization have reached the level where
commercial launch preparations can begin


One of the bottlenecks of market penetration is the limited
number of NFC
-
enabled handsets.


Another important issue is that the current trial operations
usually feature a limited number of services, without the
possibility of removal or insertion of any new or unused
service
