If you talk to people, you will find that they are in one of two camps, the first camp relies on credit cards for making purchases, and camp two doesn’t want to touch them and would only use them as a last resort.

What is a credit card?

Credit lets you buy things and pay for them later instead of taking money out of your account or not having enough money.

So, when you use your credit card, you aren’t spending your own money. Instead, the credit card company pays for everything you’ve bought and sends you a bill at the end of the billing cycle.

If you pay this bill in full when you get it, you won’t have to pay any interest.

Type of credit card

There are different types of credit cards to choose from, and it’s easy to get lost in the options. You have to figure out what kind of credit card would work best for you, your situation, and your goals.  

Here are some types of credit cards available on the market.

  • Rewards credit cards. For every amount you spend, rewards credit cards give you points, cash back, or rewards.
  • Balance transfer credit cards. Balance transfer cards give a welcome offer or introductory 0% interest rate for 15 to 21 months, allowing you to pay down debt without paying much interest. Most cards charge a 3% to 5% balance transfer fee.
  • Secured credit cards. Most credit cards are unsecured, which means you don’t have to put anything up as collateral. A Secured credit card requires a cash deposit in order to secure a credit line, which is typically the same amount. So, for example, a secured card with a £500 limit requires a £500 deposit.
  • Business credit cards. Credit cards for businesses make it easy to separate business and personal spending.
  • Travel credit cards

How do credit card works

To use your card responsibly, you must first understand how it works. As mentioned earlier, you use the cards to buy things and get to pay later when you get the bill at the end of the billing cycle. 

Every credit card company’s billing cycle is different. You can determine this for your card by either calling your credit card company or checking your credit card statement, which starts and ends at the beginning and end of a billing cycle. 

Pay your entire credit or statement balance to avoid interest. You can also pay the minimum or a different amount, and interest is charged on the outstanding amount.

Most banks allow you to set up a monthly direct debit to clear your balance. This ensures that you never miss a payment, which can have a negative impact on your credit report.

Usually, the company that issued your credit card will give you a grace period to pay off the credit card bill. This added time will end on the due date. You won’t pay interest if you pay off your balance by this date.

Many credit card companies charge annual fees that you must pay every year to keep your card, so consider this.

Pros and cons

Pros

  • Credit cards are more widely accepted 
  • Easily cancel your card if it’s lost or stolen. You’re more likely to get your money back if it’s stolen and used fraudulently.
  • You won’t pay interest if you pay off your balance each month. You have 30-40days interest-free credit.
  • Section 75 protects credit card purchases over £100 and up to £30,000. That means you can get your money back if the provider doesn’t deliver.
  • Air miles, reward points, and cashback are common credit card perks.
  • Sticking to your credit limit and paying off your card each month can boost your credit score, while even one missed payment can hurt your credit. Make sure to make payments!

Cons

  • There are plenty of studies that show that credit cards make most people spend more than they should 
  • High-interest payments and late fees If you don’t clear your balance each month (and you’re not on a 0% deal).
  • Debt can quickly compound If you don’t pay off your card each month due to very high interest
  • Missing payment can damage your credit score.
  • Cash withdrawals have additional fees and penalties.

Credit card network and Credit Card Issuer

An issuer is a bank or financial institution giving out cards and lending money to people who have them, for example, Barclays or HSBC.

Networks include Visa, Mastercard, and American Express, which are businesses that process credit card transactions.

Card networks and card issuers work together to handle customer transactions at stores.

For example, suppose you bought something from Amazon or a grocery store and paid with your HSBC credit card. In that case, you (the customer), Amazon/grocery store (the merchant), Visa (the network), and HSBC (the issuer) are all part of the payment process.

When you pay with a credit card, it sets off a chain of events. Here’s how it works:

  • At checkout, you pay.
  • Amazon tells Visa about the transaction.
  • Visa tells HSBC about the transaction.
  • HSBC will approve or deny the transaction and tell Visa.
  • Visa transmits HSBC’s decision to Amazon.

This digital communication occurs almost instantly.

Credit scores

When you apply for credit, your credit score is important. Lenders look at your credit report to figure out how risky you are and how likely you are to pay back the money. a good credit score doesn’t just affect if you will get a credit card but other types of credit you might apply for and the rates you get

Credit reference agencies are in charge of getting your credit history and storing it. Experian, Equifax, and TransUnion are the largest in the UK.

Your card affects your credit report because lenders tell CRAs about how you pay back debts. Keeping up with your card payments will help you build a good credit history. Failure to make payments will result in a negative report to credit reporting agencies.

Credit card vs Debit card

The bank accounts linked to both cards are different. Your bank account is linked to your debit card, while a bank gives you a revolving line of credit that you can access through a credit card.

This is huge because, as we have said earlier, Credit card companies pay for purchases, and you pay them back later, while Debit cards use money from your bank account.

You can call to have a fraudulent charge removed from your credit card and not lose money. However, the bank must investigate before reversing the funds if you lose money fraudulently from your debit card.

Credit cards are safer for making payments than debit cards.

Do you need a credit card?

You should weigh the pros and cons of getting a credit card for yourself to make a decision, but if you have a hard time keeping track of your finances or you worry that you might be tempted to overspend, you should avoid getting one.

But if you can manage your spending and clear your balance monthly? Then a credit card can help you buy what you need now and pay later.
