Abstract:
This paper presents the use of basic concepts of Embedded Systems and the latest technology i.e e-Purse(e-purse) which replaces the use of paperwork which we do in day-to day life for example Banking, Petro, Health, Televoice. Requirement of a special card reader, limited lifetime, acceptance being the main disadvantages of today’s traditional cards, led to the design of e-Purse . The main objective of e-purse is to make paperless money transaction easier. The main idea behind this paper is to bring in a cheaper, more versatile and much more easily usable kind of a card. Using this e-Purse the transaction procedure can be as simple as: the customer goes to the point of sale (POS), does the purchasing and when it comes to the payment, the customer submits his e-Purse to vender who connects it to his terminal (PC).The vender displays the billing information to the customer who finalizes it. The amount in the e-Purse is updated accordingly. Later at periodic intervals, the vender intimates the bank (in case of credit cards) which transfers the amount from the customer’(s) account to his. The advantages of e-Purse are its ease of use (doesn’t require a separate card reader), ease of maintenance, flexibility, safety, being the primary ones. The designing of the card is similar to any other embedded card. The designing cost of the card (e-Purse) being as low as the price of a pizza. There are ample enhancements to this application from credit cards to televoice cards. Unlike traditional cards which are application oriented, all the applications’ software can be embedded into this e-Purse which provides multi-functionality.This paper also highlights on the platform used by e-purse , security ,types of cards, and synchorinzation feature of e-Purse .
INTRODUCTION
E-purse is an electronic purse for your most important personal information
(credit cards, calling cards, passwords, PINs, account numbers and more). Like a real purse,
ePurse keeps your information in cards. You can have several related pieces of information
on a card. For example, on a password card, you might have a username, a password and a
URL. You can also personalize cards with icons, colors, and on some platforms, pictures.
To help keep your cards organized, the cards you create are stored in categories. Purse
files can have many different categories, and you can put any kind of card in any category.
In addition, you can nest categories, allowing you to place categories within categories. Like
you do with files in folders on your Windows PC, you can organize your ePurse cards and
categories however makes the most sense to you, and change how you have them organized
as needed.
You can have as many different purses as you want, and keep different information in each
one. For example, you might want to have a personal purse file for your own cards, but an
office purse file that you share with an assistant or other members of your team. You can
place copies of the same cards in different files as appropriate. For example, you might want
your business credit card listed in both of your purse files for extra.
ePurse is a system that stores a customer's data for easy retrieval for online purchases.
FEATURES OF e-Purse
1. e-purses can store your passwords, credit card numbers, email contacts and vital data like your driver's license or social security numbers. You may have your personal data recorded in several disparate locations, including your browser, spreadsheets, a PDA and on paper. Not only is it inconvenient to manage your online experience this way, but it can also be risky. Paper can get lost or waterlogged. Trying to remember and update your email contacts and credit card information can be overwhelming. An e-purse allows you to unify and store the information that you need. You will only need to remember one password to unlock your encrypted data.
2. A consumer e-purse is a standalone software application that you can download and install on your computer, PDA or Smartphone. Some of the most popular e-purse software programs also allow you to store photos and maps. You can often customize the software's data entry options to fit your needs. Many retailers also provide credit card data e-purses to their customers. These have limited features. They mainly store billing and shipping information.
3. Security:
A good e-purse uses strong encryption for stored data. The user also needs
to enter a password to open the stored files. Some e-purses employ additional password security features such as a limit on failed password attempts. Once this limit is reached, the user will be locked out.
4. Operating Systems
The ePurse application works on a variety of operating systems and platforms including Windows PC, Windows Mobile, Blackberry and Mac OS. With the upgrades made available by version 7, ePurse is also available on iPhone, iPad and iPod Touch through the Apple online store. An ePurse viewer application is available for Android devices.
5. Refillable
6. Infinite lifetime
7. Current balance can be stored and read
8. User authentication is provided
9. Universal access
ABOUT E-purse TECHNOLOGY
With the advent of computers many technologies are taking this world by a surprise. These include Embedded Systems (ES), Artificial Intelligence (AI), Neural Networks (NN), Fuzzy Logic, Bluetooth and many more are upcoming. This paper deals with Embedded Systems in a new perspective.
In easy terms, Embedded Systems can be viewed as a combination of hardware and software components, in which the software is implanted into the hardware to do the specific job. These ES were implemented in various fields from Battery chargers to Aviation Systems besides Cell phones (GSM, GPRS, CDMA, etc.). These ES are being developed in ‘leaps and bounds’. The never-ending efforts of many scientists in the field of ES led to the evolution of Smart Technology (ST).
Using the basic concept of ES, an idea for changing the future of Cards (Banking, Petro, Health etc.) is proposed in this paper. To interpret this idea, it is first needed to know the pros & cons of today’s ‘traditional’ cards. Consider the example of banking:
The magnetic stripe cards used for transactions are as simple as visiting cards, with a magnetic tape to hold the user information. The basic advantages of these cards are:
Ease of mobility
Ease of use
Coming to the disadvantages of these cards, few are listed here under:
• Easy Duplication
• Requires a special card reader
• Networking problems
• No memory to hold the current balance
• Limited lifetime
• No particular user authentication
• Unsecured remote transaction
• Limited acceptance
• Vulnerable to moisture, heat, dirt etc.
and the list goes on……
Keeping these pros & cons in view, the Smart Technology is introduced to develop a new class of cards. This stream of Smart Technology can be termed as Smart Card Technology (SCT). This smart card has a microprocessor or memory chip embedded in it that, when coupled with a reader, has the processing power to serve many different applications. Such cards can be referred to as e-Purse (electronic Purse).
The main objective of e-Purse is to make paperless money transaction easier. The electronic purse (e-Purse) is just like a leather purse as it does the same, in terms of e-cash. In today’s life where monetary value and security both, go hand in hand, it is difficult to satisfy customers using the routine cards. The main idea behind this paper is to bring in a cheaper, more versatile and much more easily usable kind of a card.
TYPES OF e-Purse Cards
e-Purse provides 31 different card types (also called templates) for you to choose from when making a new card (listed below). Each card has fields and labels appropriate for the kind of information generally kept on that card type.
For example:
A credit card provides fields for:
• the card provider
• the card type, number and expiration date
• the name on the card
• your Personal Information Number (PIN)
• the customer service telephone number
