Credit cards are often called ‘plastic money’ or simply ‘plastics.’ A credit card is issued by a bank, a financial company or a large chain of stores. A credit card allows you to pay bills or make purchases.

In simplest terms, a credit card works on the principle: ‘Buy Now, Pay Later.’ When you pay with a credit card, the issuer allows you to repay the money within 20 to 45 days.

The number of days you can enjoy credit is at the discretion of the issuer. They will inform you in advance of the exact date by which you need to repay the amount.

Types of Credit Card

Broadly speaking, there are two types of credit cards.


This is a credit card made of PVC, a kind of plastic. These are the most common types of credit cards in circulation around the world.

They have a 16-digit unique number embossed on the front, an electronic chip that contains your financial information, magnetic strip for swiping at Point of Sale (POS) machine and a paper strip that bears your signature.

There is also a three-digit CVV or card verification code for online transactions. Some credit cards also carry your picture to prevent misuse. Worldwide, all credit cards are of a standard size: 85.60mm X 53.98mm.


With online banking and countries moving towards paperless economy, you can also get a digital credit card. A digital credit card will appear on a special app provided by the issuing bank or financial organization.

The numbers are concealed for additional safety. A digital credit card will not have features of a physical one.

Instead, it will have a QR code that a merchant will scan to get payment.

You need to key-in a four or six digit Personal Identification Number (PIN) and verify the payment with a One Time Password (OTP) sent to your smartphone. They also have a three digit CVV for online transactions.

Credit Card Issuers

Worldwide, credit cards are issued by several organizations. They do so independently or in collaboration with banks and financial organizations.

Two of the largest credit card issuers worldwide include:

  • Visa International
  • MasterCard

Other credit card issuers are:

  • Discovery
  • American Express
  • Japan Credit Bureau (JCB)

The system of stores issuing credit cards is most common in the US. Giant retailers including Walmart, Target, Kohl’s and others issue their own credit cards for clients that are independent of any financial organization or bank.

For many people around the world, getting a credit card might prove difficult due to any reason. Yet, if you do wish to pay using ‘plastic’ or use alternatives to cash, you can use a debit card.

Financial companies that issue credit cards also issue debit cards. Only, stores and other entities do not issue debit cards since they are not authorized to keep your money like a bank.

Debit cards rank as the second most preferred option worldwide to pay bills or make a purchase.

Debit cards are also issued by banks and financial institutions where you hold an account and have funds.

The plastic card you use at an ATM to withdraw cash or make transactions is also called a debit card. It allows you to pay bills or make purchases in place of cash.

You can use a debit card to pay bills or buy something only if you have sufficient money in your bank account.

When you make the payment, this money is instantly debited from your bank balance. Hence the term ‘debit card’.

It is a very safe mode of payment since you do not have to worry about paying something later.

Debit cards are also available in two variants.


A physical debit card is made of PVC, bears a unique 16-digit number and an electronic chip, paper strip for signature and magnetic strip for swiping. They have a three-digit card verification code for online transactions.


A digital debit card is issued by banks that are online and provide apps for mobile banking. These cards also have a 16-digit unique number but do not bear your signature.

Once again, payment is by scanning a QR code and verifying through OTP. Digital debit cards also have a three-digit CVV for confirming online transactions.

  • Banks and financial institutions will charge a stiff fee for any cash withdrawals at ATMs made using credit cards. This is because credit cards are primarily to avail credit for shopping and paying bills.
  • You will not be charged a fee for cash withdrawals at ATMs made with debit card, provided you are within limits of the permitted free transactions. This fee varies according to bank and your location. Banks with fewer ATMs do not charge fees if you exceed the number of free withdrawals in any particular month.
  • Cash withdrawals on credit cards come with a preset limit. Meaning, you cannot avail of cash advance on a credit card over a specified amount.

Additionally, recovery agents from credit card issuers can harass you at home and office in some countries till you repay the due amount.
