CREDIT CARDS: EVERYTHING

Credit cards

It has always been inconvenient and stressful to carry money in a transaction wallet every time until a debit and credit card, or we can say plastic money, comes to market.

Advancing technology around the world, America has come up with the idea of ​​credit cards where the cardholder can perform the transaction without cash in hand. A fascinating invention, isn’t it?

Credit cards with magnetic strips:

Around 1970, IBM devised a prototype of magnetic stripe credit cards.

Instead of carrying cash, users only had to slide the card into the swap devices for the transactions to be successful, which is why it is also known as a “Sliding Card”.

Risks of magnetic stripe cards

Just as every coin has two sides, so the dark side of technology has grown day by day. With the rapid advancement of technology over the decades, it has become easier for thieves to steal cardholder card information from magnetic stripe credit cards and use that data to create a new card or copy the card either for use or for sale.

Introduction of Chip Credit Card

Introduction of credit card chip

Due to the frequently reported and credit card frauds with magnetic strips, European countries came up with the idea of ​​a Chip credit card introduced by two German brothers (Helmut Gröttrup and Jürgen Dethloff.)

Now chip card technology has become the standard among retailers around the world.

In simple words, it is a plastic card in which a microchip is built in instead of traditional magnetic tapes. This chip stores cardholder data, but in an encrypted way, which provides greater data security when performing transactions at ATMs, stores, or elsewhere.

Chip cards are also known as:

  • Smart card
  • Chip and pin cards
  • Smart chip cards
  • Chip-and-Choice Cards
  • Smart payment cards
  • Cards with chips and signatures
  • EMV cards
  • IR card

Based on EMV technology

EMV stands for “Europay, MasterCard and Visa”, the three companies that launched this initiative.

How do EMV cards solve the problem?

Earlier when magnetic tapes were used, thieves quickly copied our data after crossing the card. But in EMV technology, the card generates a unique code for each transaction, while the cardholder information remains the same.

So, even if the thieves somehow managed to copy the code from the POS (point of sale) transaction, there would be nothing they could do about it because your card will generate new code in the next transaction. This prevents fraudsters from using credit or debit card information.

How smart chip cards work

operation of smart chip cards

What makes smart cards unique is the memory chip that is built into the card’s contact card. Without that chip, it is like any other common card.

And this contact card built into the chip is the primary thing for every transaction, but a single card alone is not enough for transactions.

For successful transactions, we need a smart card along with a smart card reader to make it work.

When you slide the chip card into the card reader, then the contact pads come in contact with the card reader and immediately establish electronic interaction with each other. It gives the card reader time to analyze and verify your secure personal data from the chip. After validation, it allows you to pay through the payment system to complete the payment transaction, but not without entering the security code of the cardholder.

However, another type of smart card is available on the world market, i.e. the Contactless Smart Card. With this card, you do not need to insert or swipe the card reader to continue the transaction at the POS. Due to its practicality, it is gaining worldwide popularity day by day.

Why your smart chip card sometimes doesn’t work:

Common EMV chip card errors

There can be many reasons why your card does not work. The cause can sometimes be physical and sometimes technical. Let’s talk about some basic causes of your credit card failure in the chip:

Friction with sharp objects: your credit card chip can be damaged by the friction of keys, coins or any other sharp object that makes the card unusable for points of sale.

Wear and narrow: Constant use of your card over time can ruin your card, which may be inconspicuous to you.

But it may crash your chip and make it useless after a while. But luckily, the magnetic strips won’t affect it, and yet you can use your card.

Magnetic field effect: In this situation, when your card is exposed to external but strong magnetic fields, it would stop working because the magnetic fields can change your technical settings and reset the data in the chip.

Physical force: Credit card chips can be easily damaged by physical force. It can bend, push hard with other surrounding objects, or involuntary physical force; may lose its chip holding capacity. And most cards are damaged only by physical force.

Water: it may be raining outside and you have not safely put the card in your pocket or you have visited the beach and it has fallen out of your pocket. The chip is something technical, and you should keep your technical stuff away from water.

Trivial: if someone is constantly looping through your card, it can also stop working because it is protected by two-party authentication each time. If it detects counterfeiting, it will be locked by itself or by the company.

Scratch: never leave the card where it will be scratched. The bottom of the case or placing it with other hard metal materials can result in scratches on the chip. And once the chip is damaged, the card reader cannot read it properly, causing your card to not work.

Invalid insertion: if the card reader says “card failure” or “try again,” this may be the reason the card is inserted at the wrong angle. Therefore, it is better to remove the card and reinsert it until the card reader reads your card. Sometimes a card reader can also malfunction and destroy your chip.

Extreme heat: never expose the card directly to heat. Heater, ventilation or hair dryer are not good for your smart card chip. Direct contact with heat will cause your card to bend or change shape and ultimately will not insert properly.
