Background :

• e-Wallet a service payment application to transact virtual

money with shopping vouchers via android smartphone

(your money in smartphone as a wallet).

• Instant, flexible and simple for user

(access and protect all important your information).

• Using NFC technology on RFID contactless system with

reader/writer mode based standard ISO/IEC 14443 and

FeliCa scheme.

• Needed a system that can transfer some user data to or from

web server, activate voucher code and shopping payment.

Purpose :

• Activate account on registration-login from the application with

input Username, IMEI and PIN to get listed in web server.

• Add payment balance user on voucher card with activate 16

digits voucher.

• Expenditure transactions on smartphone apps to get closer to

logo smartposter (NFC tag) then scan it and send product

data to the web server.

Problem Limitation :

• e-Wallet app specifically for smartphone android platform 2.3

(Gingerbread) and above who support NFC tech.

• This project is only for transfer of data transaction from

smartposter to e-Wallet app and validation in web server.

• This system not discuss the network security etc.

• Only use NFC tech reader/writer operating mode with

standardization ISO/IEC 14443 and FeliCa schemes.

• Payment model made alternative with shopping voucher as

income user (buyers).

Problem Limitation : Cont…

• Assumptions shopping transactions conducted in a shopping

center where the user brings smartphone include e-Wallet

app.

• Assumptions administrator set up the transaction in the

website and of course shopping center provide free WiFi

Hotspot.

• Assumptions shopping vouchers are only available at stores

(retail) where user can buy it if their balance is less and each

of the products is mounted smartposter that embedded

information product.

THEORY

Electronic Wallet :

e-Wallet systems are common several types : Business to

Business (B2B), Business to Consumer (B2C) and Consumer to

Consumer (C2C). Suited to provide a safe way for smartphone

users to store and use online shopping information. Consists of

software and information that provides security and encryption

personal info transaction. Information like ID, PIN number, billing

and date transaction can be managed easily from server

administrator.

Electronic Wallet :

NFC :

NFC is a set of wireless connectivity based RFID tech which

uses magnetic field induction to enable communication between

electronic device within a close (<2 inch). NFC evolved

contactless system refers standard ISO/IEC 14443, operates at

13.56 MHz with data transmission speed 106 – 424 kbps

NFC defined 2 types mode operation as an initiator and a target

communication, namely Active Mode and Passive Mode.

NFC support 3 types method operation very unique compatible

smart card standard, such Reader/Writer Method, Peer-to-Peer

(P2P) Method and Emulation Card Method.

NFC :

NFC Tag

NFC tag is a small area of

programming information that can be

embedded in poster, on billboards or

ads in the product retail stores.

Dimensions for NFC tag format is

determined to be 85.46 x 53.92 x 0.76

mm (± tolerance).

The process of making tags using

RTD (Record Type Definition NDEF

Signature), to verify the integrity and

authenticity of content. The benefits

will be more secure for the long term

but weakness if you want to change

the new information then all tags must

also be replaced and it takes time and

is expensive.

Smartposter :

Smartposter is billboards or posters

displayed in public area are equipped

with contactless NFC tag, typically

RFID embedded in them. Smartposter

simplify customer interaction with the

product being advertised, smartposter

also significantly increase marketing

potential.

SUGGESTION

Conclusion :

• Network Statistics in DDMS with connection speeds an EDGE, 3G and WiFi

based on the TX (transmitter) and RX (receiver), the maximum value is 10.29

kbps which indicates that RX is always greater than TX.

• Resource usage required size of 2.36 MB so that need 2.39 MB free storage

can be installed. Heap size 9.383 MB, 8.485 MB storage allocation so

percentage of memory to used is 90.43%.

• Constraints perceived by the respondents while running this application is

Internet Connection (47%).

• App dev. suitable location according responding chose in Shopping Centers

(40%).

• Use IMEI smartphone to help authenticate user accounts with system single

user, single wallet, single account prevent misuse by other.

Suggestion :

• Expected application design must focused on security

system on the web server such as uses http security

(https) portal and added functionality for transportation

service, cinema and home security.

• Expected next project development this application not

only works on Android OS but also applied on Apple

iOS, Windows Phone and Blackberry smartphone so that

all users can benefit of this technology.
