About Smart Card

The smart card build up of the microchip integrated on it, and the bright card is made up of synthetic plastic, and the integrated chip in it is capable of saving the information and also it carries the data between the users. The Card’s data transferred to a reader which is a part of a computer system.


What is Smart Card

It includes with increases the security, and at present, they are in avail in many fields like healthcare, hospitals, banking, and entertainment etc. We further move to many levels, the users of smart card and the application fields of creative card get advantage from the features of smart card that it furnish and an example of it is the protection parameters. Some of the applications of the original ticket implemented by science are the credit card, debit card, and identification cards and also the loyalty cards. Now, due to the bringing of the high-level cards like java card as the SIM card, even the mobile phone having the feature of payment applications.

The smart card is the modern innovation in the world of information applied science. It consists of memory cards are just capable of saving the data and plays the role of a small floppy disk, but the microprocessor has the extra features like adding the data, deleting the data and handling the data in the memory that is present in the card. The smart card gives more security than the other kind of data storing devices, and quick card furnishes better solutions and increases the protecting feature of the operation.

Smart Card History

In 1968, Two Germans namely Jurgen Dethloff and Helmet Grotrupp made the plastic to be the carrier of microchips. In the passing year of 1970, Dr Kunitaka Arimura from Japan filed the first and exclusive patent on the idea of a smart card. In the year of 1974, Roland Moreno filed the original control on the active card. In the year of 1977, the three commercial people namely Bull, Schlumberger, and SGS Thomson started advancing the IC card.

In the year of 1979, Motorola advanced the first chip microcontroller for French banking. In the year of 1982, the first IC card testing had done, and in the year of 1992, a project began in Denmark on the national prepaid card.

In the year of 1999, the Federal government started the smart card identification for the federal employees.

Classification of the Smart Card:

The smart cards distributed into two categories, and they are as follows:

1 Contact Vs contactless

2 Memory Vs microprocessor

A. Contact Vs contactless: The smart card integrated with microprocessors and requires energy to work, along with it the original tickets have some techniques to exchange the information, receiving the data and transmitting the data. Few intelligent cards consist of the golden plates, and contact pads at the corner of the card, this category of the smart cards are known as the smart contact cards. The plates present at the edge of the card supply the required amount of energy and for exchanging the information through direct electrical contact with the help of a reader. The contact pad will not be present on few smart cards, and in such cards, the connection between a reader and the card will be created through radio frequency.

The contactless cards do not need a reader, and they have the serial interface, and an antenna will be present which is used to connect the card.


B. Memory Vs microprocessor: In general and the affordable smart cards are the memory cards, and they have the non-volatile memory and the electrically erasable programmable read-only memory, for example, EEPROM.

As we know Smart card is a non-volatile memory, if we displace the card from the reader or have issues with the power of power cut then the card saves the information.
The microprocessor cards are similar to the computers, and they contain the RAM, ROM, and EPROM with the 8-bit microprocessor or the 16-bit microprocessor.


The Relation Between SIM Card and the Smart Card:

The abbreviation of the Subscriber identification module, i.e. SIM is a smart card that is used for the mobile phones to identify each portable machine with the other. The mobile network furnisher furnishes this card, and it will have a unique key, and in the simple words, the SIM card is a smart card’s application that put into action the specification of GSM.

Smart Card Applications :

The applications of the smart card are
Payment system
Communication applications
Retail and loyalty

Intelligent networking
National ID or Authentication
University identification
Financial applications

Smart Card Advantages:

The capacity of storing the information will increase.

Smart Card Disadvantages:

• It assuredly was stolen.
• It needs to avail the similar reader technology.
• It is very costly.
