In this article, we will talk about what is a smart card. If you have ever been inside the metro, you are given a token and when you touch the gate, the gate opens automatically. All this is possible only due to smart cards.

A smart card is a physical card. There is a chip inside which saves your data. It is made of plastic and is similar to your driving license. It acts as a radio-frequency identification. The chip on the smart card can be either a microcontroller or an embedded memory chip. And the information inside it can be changed.

If we talk about today, the use of smart cards has increased a lot inside the world. It is also used as an EMV payment card. Smart cards capable of short-range wireless connectivity can be used in contactless systems.

There are many specialties inside the smart card and many parameters are seen inside it. In the United States, smart card standards conform to ISO / IEC 7816 and ISO / IEC 14443.

1. Smart card invention

a) In 1968 and 1969, Helmut Grötrup and Jürgen Dethloff filed patents for an identification card.

b) A memory card was patented by Roland Moreno in 1974. Which was later known as Smart Card.

c) In 1977, Michelle Ugan of Honeywell Bull had invented the first microprocessor smart card with two chips. Later, she also patented a self-programmable one.

d) Only 3 years later, this patent was used in Matrolane CP8.

e) In 2006, Exalto and Gemplus merged to become Gemalto. It was two big smart card manufacturers.

f) The smart card was first used in the French payphone launched in 1983. Now this card is also known as magstripe technology with a capacity of 300 bytes non-rewriteable.

2. How does smart card work?

There are two things inside it, one is your smart card which is passive and the other is a smart card detector. Which is active. As you go inside the metro, your token does not work when it is inside your pocket, but as soon as we take it to the gate. The gate of the metro opens automatically. The real card detector sends an electromagnetic wave inside its surrounding aria and when your card falls within its area, some of the voltage inside the chip inside it comes and sends the information to the detector.

For example, if you have worked inside a company, you get a smart card and your data is stored inside that card. When you register your presence, you have to take that card to the machine, then Machine stores the information when you have entered the company.

When you take a smart card to the detector, it transfers the data by about ‌212kbps. In which some milliliters are found. And you can reprogram a smart card 1 million times. Meaning you can punch it so many times.

3. Use of smart card inside the mobile

Friends, NFC chip is embedded inside the smart card. Which means near field communication. Now even inside mobile, Google has successfully tested the smart card. NFC chip is installed inside the mobile and after that with the help of an app, you can save your ATM card information here. After that, if you can shop anywhere with the help of it. The biggest thing is that it is very convenient. However, it is not yet used in its entirety. But with the help of this, you will be able to withdraw money in the coming time.

4. Types of smart cards

There are many types of smart cards. They are made differently depending on their type of use. Some smart card data cannot be modified inside. While some smart card data can be changed. Let's know about different types of smart cards.

a) Magnetic stripe cards

Inside this card is a strip of magnetic tape material attached to the surface. The information stored in it cannot be changed. Similar standards are used inside the bank. Your ATM also works on this principle. You cannot change every information stored inside it.

b) Optical cards

Optical cards can be read and written inside. But laser technology is used to do this. Optical cards have a capacity of several megabytes. Meaning you can store a lot inside it. ‌‌‌ It can be easily moved anywhere against a disk.

c) Memory cards

You must know about the memory card. It is also a kind of smart card. You can store data inside it, you can also use it. It is both reed and right. Meaning you can delete the information inside it and then store it again. Memory cards of different capacities are available within the market today.

d) Microprocessor cards

Smart cards with microprocessors look like standard plastic cards but are equipped with an embedded integrated circuit (IC) chip and card OS. It can store and process data as well as perform calculations. Tell you that memory cards can only store information, but microprocessor smart cards are really smart. And can actually store data. Smart cards are small and portable and can be communicated with computers and other devices.

5. What are the advantages of smart card

Friends are now increasing the use of smart cards worldwide. There are many advantages to using a smart card. The biggest advantage is that it increases security. Apart from this, it is very easy to use. Let's know about some special benefits of smart cards.

a) Processing power and security

There is a Cpu inside the smart card. And it protects the CPU information. As it intercepts the PIN, it protects it. If you enter the wrong PIN seven times, it can block you for an hour. Also, if you continuously enter the wrong PIN, it forces you to call the customer part number.

In a way, the smart card is quite good for data security. When you withdraw money inside time, you have to intercept the pin. But there is a fear that no one can see the pin. But this is not the case with smart cards. You can withdraw money by entering a PIN on your mobile.

b) It costs less to make

Friends, one advantage of using a smart card is the cost of making it is less than that of your credit card. If a lot of smart cards are made simultaneously, it reduces the cost of making them. Which can be quite dull for companies.

c) Advantage Flexibility of Smart Card

The biggest advantage of the Friends Smart Card is its flexible way. Usually, when we have accounts inside many banks, each bank has its own ATM card. But inside a smart card, you can access multiple bank ATMs and accounts with a single card.

A card can simultaneously hold an ID, a credit card, a stored-value cash card, and a repository of personal information such as telephone numbers or medical history. If it is lost, it can be easily regained. And a pin is used inside it. Without that pin, it is completely useless.

d) Very easy to use

Friends, using a smart card is very easy. There is no need to touch any kind of physical device to use them. The way you bring your card near the metro gate. The gate opens automatically. It is very easy to use. To use it, you have to go inside the frequency area of ​​the detector. After that, it starts working on its own.

e) Stability of data

Once a business or other types of information is saved inside the smart card, then it cannot be erased. It is forever. Smart card technology is also protected against electronic interference and magnets. This makes the card a good choice for storing valuable data that cannot be easily reproduced.

f) Use of smart card as an ID card

Friends have told you that inside the smart card, the person lives the entire biodata store. And it can also be used as an identity.

6. Loss of smart card

While the smart card has many advantages, it also has its disadvantages. For example, if you lose your smart card, then you may get discomfort. Apart from this, the problem of data theft continues.

a) Discomfort on eating
Friends, if your smart card is lost, then you may face serious inconvenience. If all your bank details are present in it, then after that you may face more problems. Whereas if there are different cards, the chances of losing them are less.

b) Security
Friends smart card is more secure than swipe card. But some people are not much worried about the security of their card and they write their PIN on the card. If your smart card gets lost in such a situation, then after that all your bank accounts can be empty. If anyone cares about the security of their smart card, then it is good for that only.

c) Hardware problem
Generally, the hardware to detect smart cards inside India are negligible. If you use a smart card, then the first problem you will face is where you will use it. In many shopping malls inside India, this facility is not available yet. It limits the use of smart cards.

d) Identity theft risk
Smart card hardware can be vulnerable to hacking. This means that the data inside your smart card can be altered or information can be corrupted. Usually, it can also be used inside fake works. Once the smart card hardware is hacked, it can cause a lot of damage.
