Introduction :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

topic deals with Embedded Systems in a new perspective.

Using the basic concept of ES, an idea for changing the future

of Cards (Banking, Petro, Health etc.) is proposed in this topic.

To interpret this idea, it is first needed to know the advantages

& disadvantages of todays traditional cards.

Traditional cards:

Advantages :

Ease of Mobility

Ease of use

Disadvantages:Easy duplication

No memory to hold the currentbalance

Limited lifetime

Limited acceptance

And the list goes on.

Smart card technology:

Keeping those advantages & disadvantages 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 amicroprocessor 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-Wallet (electronic Wallet).

About e-Wallet:

The main objective of e-Wallet is tomake paperless money transactioneasier. The electronic wallet (e-Wallet) is just like a leather wallet as

it does the same, in terms of e-cash.In todays life where monetary valueand security both, go hand in hand, itis difficult to satisfy customers using

the routine cards. The main ideabehind this topic is to bring in acheaper, more versatile and muchmore easily usable kind of a card.

Card Designing:

Application Specific Integrated Circuit:

Most of the home friendly electronic oriented products

works on custom specified integrated circuit chips like electric

oven, cellular phones, washing machines etc. Following this

global trend we are using FIELD PROGRAMABLE GATE

ARRAY (FPGA) belonging to the family of APPLICATION

SPECIFIC INTEGRATED CIRCUIT

Advantages of e-Wallet:Ease of use:

Withdraw or deposit value by

telephone

No signature required

Immediate payment

In the future, access points may

include mobile phones

Accessibility and convenience:

Cash machines and telephones

give more access points tofunds in bank account

Available 24 hours / 365 days

Cash machines and telephones

cannot run out of electroniccash

Flexibility:

Transfer value by telephonePay person to personFor low or high valuesMulti-currency capabilityNo age limit, so suitable for all

the family

Safety and control:Spend only what you have

Read your balanceLoad value at homeLock your card or walletKeep track of what you have

spent and where

Customer is traceable if a lostcard is found

Conclusion:With all the above mentioned features it is definite that the

future of cards is definitely e-Wallets. Besides credit cards,this e-Wallet can also be extended into the following fields,namely:

Sim card *Petro card Credit card *Health card Insurance card *Access card ATM *Tele voicecard

These are only the few to mention. Due to its ease ofadaptability to its environment, this e-Wallet would certainlychange the way people transact (monetary transactions).
