Card technology whether it be credit cards, ATM
cards and GSM mobile phones, today is no longer the monopoly of the public in
big cities, but also has expanded into smaller cities and even rural areas.
This card growth both in the number of users and the technology itself is
really sped up very quickly. One of the many technologies that are implemented
in different types of cards are SmartCard technology.
When talking about smart cards, of course you are
talking about a small chip that has been programmed to handle certain functions
and to store information that is implanted in your card. In general, there are
three models developed in the smart card industry in the world today, namely:
PC / SC: Developed by Microsoft and several other
companies. PC / SC smart card application is an interface for communication
with a PC-based smart card from Win32.
OpenCard Framework: is an open standard that
provides interoperability between smart card applications through NC, POS,
desktops, laptops, set top boxes, and so on. OpenCard should normally be used
in communication with external devices and / or use a library that is in the
client. In addition, OpenCard also provides an interface to the PC / SC to be
used for Win32-based devices.
JavaCard: first introduced by Schlumberger and is
used as a standard for Software Java Card today. Schlumberger also just use the
Java card is the only card that is currently marketed, as well as the first
company that has licensed the JavaCard the standard ISO 7816.
Smart card is different from Magnetic Card are also
quite widely used in the attendance card applications in offices and so forth,
but it has some advantages in terms of reliability, the ability to store
information that hundreds of times more, more difficult to forge. Smartcard is
quite easy to be programmed, so it allows for further development in the
application. Nevertheless, technology hardware itself is not expanding rapidly
and tends to be static
Figure 1. The standard size and components SmartCard
The standard size of a SmartCard specified by
ISO7816. If you look carefully when buying a new GSM card, then you will see
that there are two components that you may observe that his own smartcard and
smartcard substrate plastic that keep it from damage before use. Physical
characteristics of smart card based standard ISO 7816 you can see in some
applications such as credit cards, ATM cards, and so on like Figure 2.
Figure 2. Physical Characteristics of a SmartCard
Normally, a smart card does not have a power supply,
display, or keyboard. Smart card interacts with the outside world using serial
communication interface through the eight points of contact or the contact
point there.

world
The emergence of this technology, paving the way for
the emergence of the widest card-based applications are more complex and
integrated with each other's lives. So far as we know card technology in
applications ranging from ATM machines, credit cards, GSM cards, and so on.
But has also developed an application where you just
need a card just for all the applications you want to access.
One application that has been developed is a Travel
Card. Using the Travel Card, you do not need a ticket when it comes to
traveling by using aircraft, when using the phone at the airport, book a car at
the destination airport shuttle, electronic payments in several shopping malls,
and hotel room reservations.

Using the Travel Card, you no longer need to take
care of your needs for traveling abroad, for example, because it is only using
one card, you may as well take care, airline tickets, car pool, and the hotel
room when you want tempati.Bahkan you, want to contact your family in other
parts of the world, this card is changed into a phone card, and do not forget
you can buy souvenirs using this card.
Nevertheless, there are other applications that also
attract the Student Card. Using this card, a student or teacher will get a lot
of ease. When I was in the cafeteria, students or faculty can use this card as
a payment card when re-registration, payment of fees or semester
pendek.Disamping cards are used primarily for student ID card or student card.
As an identity card, this card can be used as an
access card security when students entered the lab, even as attendance card
when entering the classroom. In addition the card can be used as a phone card
and shopping card at the supermarket or cooperative campus ..
Imagine if similar systems are integrated in a giant
system of interconnected, it is certain that the system will reach the entire
community to the level of a small household.
By adding additional components such as Card Reader
households, Flexibility SmartCard increasingly feel the benefits. Through a
Set-Top Box is connected to the Internet which is equipped with a Smart Card
Reader, you do not have far to shop, book movie tickets, book a queue to see a
doctor, hotel reservation, and thousands of other applications. When SmartCard
becomes an identity card and a representative yourself, then perhaps the value
of the card is almost equal to the value yourself. You can use just a card just
in Schools, shopping centers, airports, stations, office, and in all the places
where you are.
Figure 5. Just a few examples of applications illustrate
the integration of course, but in fact a system with a very complete
application can be described again, but due to space limitation, only a few
applications that can be displayed.

card applications in the household
