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 today’s ‘traditional’ cards.
Traditional cards:
Advantages :
Ease of Mobility
Ease of use
Disadvantages:
Easy duplication
No memory to hold the current balance
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 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-Wallet (electronic Wallet).
About e-Wallet:
The main objective of e-Wallet is to make paperless money transaction easier. The electronic wallet (e-Wallet) is just like a leather wallet 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 topic is to bring in a cheaper, more versatile and much more easily usable kind of a card.
Salient features of e-Wallet:
More than 40 years of data retention
Firewall encrypted security logic
Compatible with many supporting hardware.
No separate card reader is required to access our card
Polarity reversal indicator is pre-built in our card.
Reusability of our card is unlimited.
Multiple card features are incorporated in the same card.
External complexities are less
Example for transaction:
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
Internal Architecture of FPGA:
Internal blocks of FPGA IC are:
Embedded micro controller
Crypto coprocessor
Random Word Generator
On chip security power management
Access control
Flash ROM/ROM
EEPROM
RAM
Serial interface
RF Interface
Internal 16 bit address/data bus
Operation
Features of e-Wallet:
Refillable
Infinite lifetime
Current balance can be stored and read
User authentication is provided
Universal access
Maximum possible cash
Cannot be duplicated
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 to funds in bank account
Available 24 hours / 365 days
Cash machines and telephones cannot run out of electronic cash
Flexibility:
Transfer value by telephone
Pay person to person
For low or high values
Multi-currency capability
No age limit, so suitable for all the family
Safety and control:
Spend only what you have
Read your balance
Load value at home
Lock your card or wallet
Keep track of what you have spent and where
Customer is traceable if a lost card is found
