Service Computing &

MoneyMind Mash-up

What is Service Computing?

Service Computing

Self-contained, platform-independent method of bridging the gap between

business and IT

Businesses can find, utilise and create their own services and integrate them

with others to create a tailored system to match their business needs

Technology includes: Web services, service-oriented architecture (SOA), cloud

computing and many more

What are its impacts?

Global Impacts

Most obvious impact is between businesses globally and their interaction

Large companies like Microsoft putting cloud computing as a top priority

IBM spent $360 million on building a cloud computing software centre in NY

Estimated by 2014, 30% of Global 1000 companies will use two or more cloud

services up from 5% today

Local Impacts

Less cost on businesses

Use PAYG (or subscription)

based services

Flexibility for upgrade –

providing “on-tap” IT

capability for start-ups,

spikes in workload, etc.

Integration of business and IT

systems, allows businesses to

easily interact with and

upgrade where necessary

Personal Impacts

Mobile applications as web services

Capability to access web services from all locations – integration of systems

Increase in cross-platform capabilities

More rich applications where processing can be done server-side and the

phone doesn’t need the processing power

HTML5 further enhances them with APIs such as Google Charts

What Web Services will be used

in MoneyMind?

PayPal – Access and Use in App

Accessed through the PayPal Adaptive API

The PayPal API uses both RESTful and SOAP protocol and responses can be

formatted as XML, JSON or NVP

Encryption over HTTPS

XML is used as the chosen response format. This text-based information allows

for easy storage within the application’s transaction database

Google Maps - Functionality

Google maps can be used on both a personal and a business level.

Personal - Finding directions and locations of key areas.

Business - Businesses can use Google Maps in websites and applications.

The Google Maps API allow for the embedding of Google Maps onto web pages of outside developers, using a simple JavaScript interface or a Flash interface. It is designed to work on both mobile devices as well as traditional desktop browser applications. The API includes language localization for over 50 languages, region localization and geocoding, and has mechanisms for enterprise developers who want to utilize the Google Maps API within an intranet. The API HTTP services can be accessed over a secure (HTTPS) connection by Google Maps API Premier customers.

Within our application, Google Maps integration with transaction history would provide the user with a visual representation of where their money is being spent, and would help them target specific locations or stores in which they need to budget.

Google Maps – Owners and providers

Google Maps is owned and operated by Google.

The intended audience of this service are businesses and developers that

want to have an accurate map system in their application.

Google Maps - Constraints

Quality of service dependent on internet coverage. Additionally, if no access

to internet, PayPal cannot be used.

Google Maps – Pricing Factors

Google maps have no costing policy as they make their money off

advertisements and selling data.

Google Maps – Legal Factors

It is important to remember that people’s locations are being recorded and to

consider extra security so people’s privacy is not at risk.

The data can be sent over the HTTPs encryption, giving the data an added

level of security

Google Maps – Access and Use in App

Accessed through Google Maps adaptive API.

The API is accessed by grabbing the functions in a simple JavaScript attached

to the application.

APIs can talk over multiple encryptions such as HTTP and HTTPs.

Proximiant - Functionality

Application used to create digital receipts from specific transaction data

While the application also includes a bump-to-pay feature and NFC tagging,

only the functions required to produce the digital receipt are needed and the

information used will be stored within the database.

Digital receipts are also location-based

Both iPhone and Android application

Proximiant – Owners and providers

Owned and provided by a Silicon Valley-based start-up Proximiant

Intended audience is smartphone users (generally from between the ages 18

and 30 - due to bank implementation) who wish to obtain efficient

transaction records to create a smart shopper

Proximiant - Constraints

While NFC-payments are constrained by transceiver availability, we are only

interested in the functions required to generate the digital receipts and

hence this constraint is eliminated.

Quality of service dependent on internet coverage. Additionally, if no access

to internet, Proximiant cannot be used.

Proximiant – Pricing Factors

Proximiant is a free service, provides perfect business application

Proximiant – Legal Factors

Proximiant develops digital receipts based off information, in this case we

would utilise the XML data stored in the database, without having to share

personal information such as email address

Additionally, data is stored in secure servers app sent via encrypted HTTPS

Proximiant – Access and Use in App

SOAP, HTTPS, XML FILES -> Converts to digital receipts

Google Charts - Functionality

Used to visualise data into graphs/charts for mainly a Business perspective but can be used for personal use. This may vary from small line charts to a complex hierarchical tree.

Personal: Used for small visualisations of data. for example, a small presentation

Business: Businesses can use Google charts to visualize their data for things such as work presentations, Business meetings or just for general use.

The most common way to use Google Charts is with simple JavaScript that you embed in your web page. these charts are rendered using HTML5/SVG technology so that it can be compatible with all common browsers.

To create these charts, a Datatable is used to sort, modify and filter all data that can be directly imported onto a webpage.

Google Charts – Owners and providers

Google Charts is owned and operated by Google.

The intended audience for this is for businesses to make a clear, visual

representation of their data towards other businesses or within their own.

Google Charts - Constraints

Operating goggle charts requires internet access to operate. Although saved

images of data can be taken for use outside of Google charts.

Google Charts – Pricing Factors

The Google charts website states that Google charts is completely free and

guarantees three years compatibility.

Google Charts – Legal Factors

Their is a small risk that people can obtain your data through breaching

specific networks.

HTTPs can be used to make the use of their business data more secure, with

the added level of security over the network.

It states within the privacy region within Google charts that Google does not

share or obtain data that you have uploaded with other charts outside of your

account.

Google Charts – Access and Use in App

The Google Chart API lets you dynamically generate charts with a URL string and

embed these charts on a web page, or download the image for local or offline use.

The Google Chart Tools enable adding live charts to any web page. They provide

advantages such as a rich gallery of visualizations provided as image charts and

interactive charts and they can read live data from a variety of data sources

Users embed the data and formatting parameters in an HTTP request, and Google

returns a PNG image of the chart. Many types of chart are supported, and by

making the request into an image tag the chart can be included in a web page.

The API is accessed by grabbing the functions in a simple JavaScript attached to

the application.

APIs can talk over multiple encryptions such as HTTP and HTTPs.

So what is MoneyMind?

Application Overview

Powerful, easy-to-use money managing application

Purpose is to allow users to use their phone to:

Pay using NFC (Bump-to-pay)

Collate Digital Receipts

Organise receipts into powerful Infographics

Track expenditure

Budget

Become more ‘money aware’

Platform

Application was chosen to run on Android exclusively. This is due to the

following reasons:

NFC feature is not available in iPhones – they do not have an embedded NFC chip

Hence they would not be an effective device to use with the application

As the main purpose of the phone is to provide a unified, complete finance

management package the necessity of this NFC feature is vital

Android applications are written in Java, which would effectively integrate all the

web services easily

How is better value generated?

Currently, methods of payment and transaction tracking are limited, despite

this age of technological advancement - for example, the fact that we still

use paper receipts

The purpose of MoneyMind is to provide users with a visual representation of

where their money is being spent, as well as integrating current payment

methods through the use of PayPal, and payment tracking methods through

the use of Proximiant digital receipts and Google Maps.

As well as having the ability to use the bump-to-pay feature through PayPal,

users have on-hand access to graphical representations of where their money

is being spent, for example. in the past month they 70% of their expenditure

was for purchasing food.

How is better value generated? (contd.)

By utilising the information through the PayPal transaction data such as: store

locations, store type, amount spent, products purchased etc. can then be

delivered into services such as:

Google Charts - to create a visual representation of spending habits and allow the

user to become money-aware

Google Maps - so that users can see location-based spending habits and determine

areas or stores in which they are purchasing too much items

Proximiant - to create a neat digital receipt, and allow the user to search through

their purchasing history. Proximiant also provides the user with discounts and

coupons based on their purchasing history. GPS-data can be synced with Proximiant

to enable this feature.

Strengths and Limitations

Strengths Limitations

Integrates the four web services to

create a powerful financial

management tool

Internet connection is required to use

the payment, Google Maps and Google

Charts features

Eliminates the need for physical

receipts

Data and privacy concerns – Data must

be kept secure at all stages throughout

the app and data messages encrypted

Eliminates the need for multiple bank

accounts, cards etc.

Lack of NFC features within iPhones

disallow the use of bump-to-pay.

User-centred design that focuses on the

app being user-friendly and easy to use

Beautiful Infographics that allow

effective representation of spending

habits

Google Maps integration to show

location-based spending habits

What would it look like?

Marketing

Social media outlets as platforms to reach our target users

Target users are between 18 and 30 year old (smartphone users)

Users are money-conscious shoppers

Free versions of the app will be sent to reputable app reviewing websites,

such as App Advice

Websites and blogs focused on Finance industry, such as DailyFinance.com will

be sent a copy to test and publish on their site

Utilise Google Ads to ensure high-priority in searches

Use Google’s alert system

Future Directions

In the future new integrations could be added to this application:

Integrate more banks to this application so any bank accounts can be used and not

just PayPal

Integrate voice recognition so that the user can ask the application basic questions

about their monetary status.

Expansion of the application so that it can be used on iPhones, which would come

with the addition of an NFC chip in the iPhone

Turn this application into a web service by creating APIs for this application so it

could be integrated into other web applications

Introduce extra security such as finger printing or voice recognition so that money

cannot be stolen
