In mature markets, credit cards tend to replace cash and checks as the most common payment mechanism, thanks to its greater safety, convenience and broad acceptance. A credit card is a plastic card with a magnetic strip that contains data and is a financial instrument that allows the holder to pay for goods or services on credit instead of cash. While credit card companies provide the infrastructure for settlement of transactions, the cards are issued by banks and increasingly by retail outlets and consumer-oriented entities.

Credit cards allow customers to buy goods and services immediately and then pay the aggregated transactions at a later date. Debit cards, on the other hand, allow customers to buy funds directly debited from their accounts.

Visa and Mastercard are the two largest credit card companies worldwide. Both were originally formed by consortia of banks. Indian Express is both a provider of credit card and bank.

If you have a card with a strong balance carried over each month, you should consider transferring the debt to a different company. Several issuers offer 0% APR on balance transfers credit card. The honeymoon period usually lasts about 12 months, although some of the best credit cards for balance transfers offer interest rates during free time at 13 or 15 months. This may provide some welcome respite to settle the debt without accruing interest. When the grace period ends the APR back to the standard, which varies, depending on the credit card in the UK that you choose and your credit rating.

Individuals who are concerned about the debt should switch to a card charging 0 percent of the balances for an introductory period and the objective is clear what should be within that period of time. If this is unlikely, go for a card offering a low rate until the balance is completely cleared.

Balance transfer rates can be a sting in the tail, so be sure to take into account when comparing rates.

Those who have remained loyal to their bank and never changed their credit card are most likely to be charged excessive interest rates.

It has never been easier to switch deals, and there are a wide variety of supply.

Before we discuss about the credit card process, let’s first look at the players involved in the credit card business:

Credit Card Holder : The person who is issued a credit card, who actually holds & uses it. He purchases various things through the card & pays the borrowed money later within a scheduled time to the bank or the company.
Merchant/Shop-keeper : The person who accepts the payments from the card holder through the swiping of the credit card in return of the transaction.
Card Issuing Bank : It is the bank which has actually issued the credit card to customers & offers credit to them on transactions made by the card holder.
Acquiring Bank: All the transactions made using the credit card is done through the acquiring bank. The merchant pays a fee to the acquiring bank for the signing of machine & other services.
Credit Card Network : This is that network which helps facilitate the card transactions such as Visa or Master Card.
