How do Credit Cards Work?

Credit cards can be a very beneficial way for people to spend flexibly and easily. However, for people who are irresponsible financially or may not be able to pay their bills on time, accumulated interest and extra fees can make late payments costly.

Functionality

Card issuers offer credit cards to individuals, and in return, they will receive interest fees for late card payments. When a card issuer grants a credit card, they will be giving the cardholder a line of credit from which the holder can make payments. Then, whenever the credit card is used, cardholders are practically paying merchants with a loan from the card issuer. Thus, the card issuer will make the payment to the merchant, and the cardholder will be responsible for paying the card issuer back on time; if the payment is not made on time, then cardholders can expect late fees and interest payments.

All credit cards use a magnetic strip and many now have chip technology in order to verify that the cardholder has sufficient funds to make purchases. When your credit card is scanned by retailers, the electronic verification system is checking to ensure that you have enough credit to make the purchase.

On a credit card, there is a long credit card number. The first 6 digits of this number represent what bank the card is from. The subsequent digits are personalized so that all individuals have their own, specialized card number. The credit card will also have a security code on the back, which can be used for online or over-the-phone purchases to ensure that someone has not stolen the credit card number. The card also has an expiration date, after which the card will be unable to make purchases.

Interest and Fees

Credit card issuers make money by charging interest on unpaid credit card statements. Each month, you will receive a credit card bill with a minimum amount of money that must be paid. If you miss this payment, you may be charged late fees, and your interest rate also might be raised.

If you are a responsible credit card user, you will make at least the minimum payment on time, if not the entire payment. If the payment is not made in full, then you will be charged interest on the entire payment, not just what is outstanding. This means that if you buy a $500 plane ticket and pay all $500, you will be charged no interest. However, if even $1 is unpaid, you will be charged interest on all $500. Thus, it is very costly to not pay your bills on time.

Credit cards come with a myriad of other fees, including foreign transaction fees, balance transfer fees, cash advance fees, return payment fees, and many more. Also, many cards have an annual fee, charging you yearly for ownership of the card. These fees vary per credit card, so you should investigate these fees before choosing which card you want to own.

Pros and Cons

Some benefits of credit cards include that they are easy to use and are accepted at most retailers. They are safer than cash because if they are stolen, you are able to cancel your credit card immediately and block purchases. They also allow you to spend now and pay later, if you do not have all of the money you need to make a purchase. Lastly, credit cards are usually protected from fraudulent transactions and many come with built-in rewards, offering cash back or points on all purchases.

Some incentives that credit cards offer include a signup bonus, 0% APR periods in which you pay no interest, and elimination of fees such as foreign transaction fees.

However, credit card users should be cautious. As mentioned before, there are a lot of fees that accompany credit card usage. Also, high interest payments can lead to increased debt, which can be hard to climb out of.

Types of Credit Cards

There are many different types of credit cards, all with different benefits. Cash back and rewards cards will offer points and other incentives for using this card, which can be redeemed for different rewards. Popular rewards cards include many travel cards, which offer points toward flights and travel. 

Secured cards are safer for people with low credit score, as you have to make a security deposit so that it is easier to make your payments. The line of credit you receive will be around 50% - 100% of the deposit made, ensuring that your payments are reached, which can help you raise your credit score. Higher credit scores prove that you are more reliable, so banks will be more likely to offer you a loan. 

Other types of credit cards include student cards, airline cards, fintech cards, and many others, all with different benefits.

Conclusion

Credit cards offer the cardholder flexibility with their payments, while also giving a variety of rewards and other benefits and protections to people who use them. However, you must be careful when using a credit card, or else fees and interest payments could put you in a debt spiral.
