Smart card is defined as a card with IC ( integrated circuit ) which planted in it , and the IC is used for information process , and has its own storage media with capacity . Before maybe , you’ve heard about magnetic stripe card which also can be used for transaction . Today this magnetic stripe card much used for ATM card in Indonesia , which also considered as transaction . Smart Card is different with Magnetic Stripe Card which is an old technology .
Magnetic smart card has an easy look characteristic , just see the magnetic ribbon on the card . Meanwhile , IC in the smart card is inside the card or it can be a small chip . Of course by using both mangetic ribbon and IC / chip altogether , the card can be used as smart card and magnetic stripe card . Both magnetic stripe card and smart card keep the information in its own storage media ( magnetic ribbon in magnetic stripe card , IC / chip in smart card ) . To read and write information , we need a card reader or an encoder . Example , you can easily find a reader when you go to an ATM , which has a reader inside it to read the information from the card you insert to it .
It also when you skrecth the card when you do a transaction . Big usement and booming smart card happened in 90’s , when smart card based SIM ( subscriber identify module ) , which also used in GSM cellular . The credit card and debit card used as payment tool by master card , visa , and europay making the smart card become popular in the public . The next development is contacless in smart card . The contacless technology is making the communication with reader by frequences or gennerally known as RFID ( radio frequency identification ) is possible , which making the card and the card do’t have touch directly ( contacless ) .

Smart Card's Definition
this Technological appearance, making way which the was him of for applications appearance base on more card [of] komplek and each other integrated with human life. During the time card technology which we recognize centred around application [in] machine of ATM, credit card, card of GSM, etcetera. But had also been developed [by] a application where you only needing a just card for all applications which wish you access. One of [the] application which have been developed [by] is Travel Card. By using this Travel Card, you [do] not need ticket when have to travel by using plane, when using telephone set [in] airport, ordering fetching car [in] airport of[is target of, payment of electronic [in] some shopping centres, and hotel room;chamber reservation
By using Travel Card, you needn't again to manage requirement of you during traveling to abroad for example, because only by using one just card, you earn at the same time manage, plane ticket, fetching car, and hotel room;chamber which wish you isn't it when you, wish contacted your family [in] other world cleft, this card change function become telephone card, and do not forget you earn bought present by using this card.
Nevertheless, application there [is] still other which also draw that is Student Card. Using this card, a lecturer or student will get many amenities. When residing in canteen, lecturer or student can use this card as payment card, when re- registration, payment of SPP or short semester. Beside the core important this card is used for the card of student identity or student card. As identity card, this card can be used as [by] card access security when student enter room of praktikum, even as absence card when entering lecture hall. Besides this card can be used as [by] card phone and expense card [in] campus supermarket or co-operation..
Conceiving if only systems is of a kind integrated in a giant system which was interaction, hence can be ascertained [by] the the system will reach entire/all society to level the smallness that is household.

Rumah makanadded additional component in the form of Card Reader [in] households, Flexibility of Smartcard progressively felt his benefit. Passing a Set-Top Box which incircuit with Internet provided with Smartcard Reader, you needn't far to go shopping, to ordering cinema ticket, ordering queue to check to doctor, hotel reservasi, and thousands of other application. When Smartcard become identity card and representative yourself, hence perhaps assess that card almost [is] equal to value yourself. You earn to use only a just card [in] School, Shopping Centre, Airport, Station, Office, and [in] all places where you reside in. Picture 5. Only defining integration some just application example [of]s, but in fact a system with very complete application can be portrayed again, but because keterbasan of room, only some just applications able to be presented.
Model Smart Card
If you talk about smart card , then you’re talking about a small chip which is programed to handle a specific function and also to keep information which planted in your card . Generally , there’re three developing smart card model in this world nowdays : 1. PC/SC : developed bu microsoft and some other companies . PC/SC is an interface smartcard apllication to communicate with smart card from PC based on win32 . 2. OpenCard FrameWork : an open standard giving an operation between smart card apllication throught NC , POS ,Desktop , laptop , set top box and others . 3. javacard : introduced first time by Schlumberger and used as standard card for java software todays . Schlumberger too , only use java card as the only card in the market now , and also as the only company which has javaCard license which is ISO 7816 standard . 
Smartcard different from Magnetic Card which also quite a lot used in absence card applications office and others, but have some excesses in the case of mainstay, ability to saving hundreds of times more many information , more is difficult to spurious.Smart card easy Enough for program, so that possibly to be developed furthermore beside his application. Nevertheless, hardware technology do not expand swiftly and tend to staticly.
Standard gauge from a Smartcard determined by ISO7816. If you pay attention carefully when buying new card [of] GSM, hence you'd see that there are two your which can component perceive that is smartcard-nya alone and the plastic substrat of taking care of smartcard-nya of damage before used. Physical character of card smart based on standard of ISO 7816 earning you see [at] some applications like Credit card, card of ATM etcetera like Picture hereunder.
Smart Card Reader
[So that/ to be] there are clear boundary, You need to make a[n module ( possible was You need the giving of name, for example module of Smart) which accommodating requirement till this phase. Comands of used programming it is possible that differing if You use FIRE or of SDK different, but elementary function [of] him being equal. Rest outside module of Smart above, is [common/ public] database application, and menyimpan of memroses data, [doing/conducting] needed calculation, presenting report, and others
If in a moment You make other application which use card smart, You earn re-using module re-use) of Smart above, and concentrate on business process [in] database and application. Information in possible card smart have selected format, for example written in character of hexadecimal.For that, a set or library of function conversion need You prepare. To support security, there [is] good [of] Your him [do/conduct] enkripsi [at] important information wishing to be kept [at] card smart. From a simple application, [is] not [do] not possibly round into more complex application like example [of]s which have been explained above. In this case, all possibility which earn to be thought of to become system security gap have to anticipate better.
Contactless Smart Card
As have been explained before all, card smart contactless communicate with technology and reader of RFID. In card smart contactless there are RFID tag or of transponder as kasi identifi use radiowave. RFID is also recognized with term of proximity or of proxy. Do advantage of compared to card smart contact? Smart card Contacless work more practical, especially for transaction requiring process quickly, the example is usage of card smart contactless [at] transportation system like MRT ( Mass Rapid Transit), where You earn to [do/conduct] transaction, without require to [release] card of Your purse.
Like [at] card smart contact, card smart contactless also have standard kasi klasifi, owning support differ [at] range ( selected jarak) [among/between] and card of reader. There are some standards of internasio nal to support application which is spesifi k. For example ISO 18000-3 used as [by] standard of tag high-frequency, and ISO 18000-6 for the ultra-high of frequency. ISO 15693 is popular standard, and use high-frequency 13,56 MHZ, what was widely used for the credit card of. Smart card Contactless nor use battery, but card smart contactless have inductor which is build-in to catch trouble of sinyal radio frequency, and use him as source of power [at] IC.
Even though, enabled [by] a card smart contactless have or battery of power internal supply, or referred [as] [by] RFID tag ngan de the activeness. this Ngan ability De, is enabled [by] communications distance till hundreds of metre with tired battery resilience 10 year, and also can support big depository capacities. Farther [regarding/ hit] example [of] usage of card smart which have been applied [by] is Octopus card, which have been gone into effect [by] [in] Hong Kong. Octopus Card is card smart contactless used for the payment of electronic onlinely and ine offl.
Card Octopus [do] not can only be used for the system of transportation, but also as medium of exchange [at] supermarket, shop, restaurant, park, and POST application ( Point Of Sales) like station service and of vending machine. In brief, only by satu card, can be functioned to various need of payment.

Example [of] of Contactless Smart Card :
MIFARE is a[n technology of contactless recognized card smart wide [of], provided with and card of reader. Technological [of] MIFARE pursuant to ISO 14443, with frequency 13.56 MHZ. MIFARE used many for the applications of e-wallet, control access, Card ID, ticketing, and others. From capacities side, there are MIFARE Standard 1k owning depository capacities 768 byte, consist of 16 sector, where the each sector of diproteksi by two different key ( A key and of key B). MIFARE Standard 4k owning capacities 3 kilobyte, what consist of 64 sector.
Security
Conversing to [regarding/ hit] a system, more than anything else if used as [by] payment system, hence security side is indivisible matter of itself system. A risk which is is proper to be considered [by] is excellence of tracking yielded by RFID potency tag can read widely, is so that enabled [by] other party know possible location have the character of secret or privat, good in the bearing of with importance of individual security, company, or military. Of course system which wish You apply by using card smart or of tag RFID, have to beforehand consider above possibility and or other risk. Card Smart alone have supplied with kriptografi by hardware, by using algorithm of enkripsi ( for example RSA, DSA, and others) yielding unique key. This matter cause duplication card smart cannot easily. Through good tidiness [at] card, data [at] chip also can protect so that hold up to water and dirt.
Contact Smart Card
Eight contact with external worldContact smart card has a gold tiny chip in it . When read by the reader , the chip will conecting wtih the conector which can read the information from the chip . In the contact smart card , a few ISO standartization has been established to define the physical shape , position , characteristic , protocol , sending command , and back respond , card resistance , untill the function . The card also doesn’t have its own battery .
In Aladdin story , there’s a magic lamp . If scratched it will appear a powerfull geane which can fullfill all wish . because of technology development , you don’t have to feel down of geane magic lamp . Today , you just need to open your wallet and take out a card , and only with a scratch , slowly you’ll have a new shirt .
Normally, a smart card do not have to ration energy, or keyboard. Smart Card have interaction with external world use serial communications interface pass eight dot contact or existing point contact.
