CREDIT CARDS: YOUR EVERYTHING
It was always inconvenient and stressful to carry cash in your wallet for transactions every time until the debit and credit card, or we can say plastic money came into the market.
With the advancement of technology all over the world, America came up with the idea of credit cards where the cardholder can do the transaction without cash in hand. Fascinating Invention, isn’t it?
Magnetic Stripes Credit Cards:
Around 1970, IBM came up with the prototype of magnetic stripes credit cards.
Instead of carrying cash, users just had to swipe the card in swiping machines for transactions to be successful, and that’s why it is also known as “Swipe Card.”
The downfall of magnetic stripe credit card
Like every coin has two sides, here also the dark side of technology was growing day by day. With the rapid advancement of technology over decades, it became easier for thieves to steal the cardholder’s information from the magnetic stripes credit card and use that information to create a new card or duplicate the card either for their use or to sell them.
Introduction of Chip Credit card
Because of high reported fraud and scams with Magnetic stripes credit cards, European countries came up with the idea of Chip credit card introduced by two German brothers (Helmut Gröttrup and Jürgen Dethloff.)
Now chip card technology has become the standard at merchants throughout the world.
In simple words, it’s a plastic card that holds a microchip embedded in it instead of those traditional magnetic stripes. This chip stores cardholder information but in an encrypted way, which provides more data security when making a transaction at ATM, 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
- Chip and signature cards
- EMV cards
- IC card
Based on EMV Technology
EMV is the acronym for “Europay, MasterCard, and Visa,” the three companies that began this initiative.
How do EMV cards solve the problem?
Earlier when magnetic stripes were in use, thieves quickly copying our information after getting card swiped. But in EMV technology, the card generates a unique code for each transaction while the cardholder’s information remains the same.
So even if the thieves somehow managed to copy the code from POS (point of sale) transaction, they could do nothing with that piece of information as your card will generate new code in the next transaction. This makes it impossible for fraudsters to use credit or debit card information.
How Smart Chip Cards Work
What makes smart cards unique is the memory chip, which is embedded in the contact pad of the card. Without that chip, it’s just like any other regular card.
And this chip embedded contact pad is the primary thing for any transaction, but the only card itself is not enough for transactions.
For successful transactions, we need a smart card along with a smart card reader to function.
When you swipe your chip card in a card reader, then the contact pads come in contact with the card reader, and instantly, they establish electronic interaction between each other. It gives time to the card reader to analyze and check your secure personal information from the chip. After validating, it enables you to make payments through the payment system to complete the payment transaction but not without entering the cardholder’s security code.
However, there is one more type of smart card available in the world market, i.e., contactless smart card. With this card, you don’t need to insert or swipe with a card reader to continue the transaction at POS., and because of its convenience, it is gaining worldwide popularity day by day.
Why your Smart chip card does not work sometimes:
There can be many reasons why your card is not working. Sometimes the cause can be physical, and sometimes it’s technical. Let’s discuss some basic causes for your chip credit card malfunction:
Friction with sharp objects: your credit card chip can be damaged by friction with Keys, coins, or any other sharp object rendering the card unusable for point-of-sale payments.
Wear and Tear: constant use of your card over time can get frayed your card, which might be unnoticeable to you.
But it may it will tear down your chip and make it useless after a point of time. But luckily, magnetic stripes won’t get affected by it, and yet you can use your card.
Magnetic field effect: in this situation, your card when exposed to external but strong magnetic fields, it would stop working as magnetic fields can alter your technical settings and reset the information in the chip.
Physical force: chip credit cards can get easily damaged by physical force. It can bend, pushed hard with other objects of surrounding, or by unwilling physical strength; it can lose its chip holding capacity. And most of the cards get damaged by physical force only.
Water: it may be raining outside, and you did not put your card safely in your pocket, or you visited a beach, and it fell from your pocket. Chip is something technical, and you should keep your technical things away from water.
Fiddling: if someone is constantly fiddling with your card, then also it can stop working because it is protected with authentication from two parties every time. If it detects falsifying, it will lock itself or by company.
Scratch: never leave your card where it will get scratched. The bottom of your purse or putting it with other hard metal materials can result in scratch on-chip. And once the chip got damaged, the card reader can’t read it correctly, which causes none working of your card.
Wrong insertion: if the card reader is saying “failure” of the card or “try again,” then it may be the possible reason that card is inserted at a wrong angle. So better to remove your card and insert it again tills the card reader reads your card. Sometimes, the card reader can also be malfunctioned and destroy your chip.
Extreme heat: never expose your card directly to heat. Heater, ventilation, or dryer, they are not well-wisher of your chip smart card. Direct contact with heat will cause your card to bend or change its shape, and ultimately, it will not insert properly.
