Credit cards can be used as a substitute for cash to buy goods or services. This is more convenient than cash because you don't have to go to an ATM to withdraw money all the time when you need to purchase something.
Though, unlike a debit card, you are actually borrowing money when you spend the card issuer: you return the money at the end of the month when you receive a statement with your purchase. So if you default on your balance, you'll usually have to pay interest on your debt unless you have a card with a 0% offer.
Apart from all these, there is also a factor that you need to understand about credit cards. Due to the presence of so many technology banks are also now making use of it by providing custom designs that are available in large numbers.

Understand Credit Limits:
Your credit limit is the maximum cumulative amount you can spend on your card. If you try to exceed your limit, your card will be rejected at the point of sale.
Your card issuer regularly reviews your credit limit and may increase your limit over time. You can also request an increase. You may want a higher limit if you have a really low limit or a one-time bill you couldn't pay otherwise. Though if this is the latter case, be careful.
Card issuers often raise your credit limit, whether you want it to be increased or not. Credit card companies do this to encourage you to spend more money. Of course, your publisher is dressing you up like it's helping you by writing a letter congratulating you on your boundaries. Just ignore the hike and resist the temptation to spend more just because you have extra credit.
