a virtual A smart card resembles a credit card
in size and shape, but inside it is completely different.
The inside of a smart card usually contains an embedded
8-bit microprocessor. The microprocessor on the smart
card is there for security. The host computer and
card reader actually "talk" to the microprocessor.
The microprocessor enforces access to the data on the
card. If the host computer read and wrote the smart
card's random access memory (RAM), it would be no different
than a diskette.
smart card may have up to 1
kilobyte of RAM, 24 kilobytes of ROM, 16 kilobytes of
programmable ROM, and an 8-bit microprocessor running
at 5 MHz. The smart card uses a serial interface and
receives its power from external sources like a card
reader. The processor uses a limited instruction set
for applications such as cryptography.
smart cards are very much popular
in Europe than in the United States. In Europe, the
health insurance and banking industries use smart
card extensively. Even though smart cards have been
around in their modern form for at least a decade, they
are just starting to take off in the United States.
Magnetic stripe technology remains in wide use in the
United States. However, the data on the stripe can easily
be read, written, deleted or changed with off-the-shelf
equipment. Therefore, the stripe is really not the best
place to store sensitive information. To protect the
consumer, businesses in the U.S. have invested in extensive
online mainframe-based computer networks for verification
and processing. In Europe, such an infrastructure did
not develop -- instead, the card carries the intelligence.
The most common smart card applications
are:
- Credit cards
- Electronic cash
- Computer security systems
- Wireless communication
- Loyalty systems (like frequent flyer points)
- Banking
- Satellite TV
- Government identification
smart card solutions bring
security, expediency and accessibility to people worldwide.
Smart card –based solutions are being used in
a wide range of applications from mobile telephony to
CRM, loyalty, and to the development of next generation
applications and services. In applications like Electronic
cash, Security, Access control, Transportation and RFID
/ IC Tags, smart card solutions are proving to be of
great value.
Looking for an all inclusive development
system for building compact, efficient smart card
programs? A good number of development systems for smart
card applications entail costly, complicated simulators,
emulators, and other awkward tools. In such a scenario,
a company that unites you directly to the card, applying
unique "cross-target link" or XTL, definitely
is a good service provider. With such technology, you
could be able to examine data space, even define new
commands right from the command line and test them immediately.
The XTL can write to flash and EEPROM on the fly, so
you seldom have to download the program using the bootloader.
This helps you test your programs incrementally, dramatically,
reducing your development time. WE-SC's programming
environment helps you write simple "scripts"
to send APDUs to your card, and make out the results
yourself. It's a complete programming and testing environment
with one convenient user interface.
