You can also call it a check card or a bank card. It works very much like using cash. However, the money stays in your bank account until you use the card. When you buy something, the money moves from your account to the shop right away. This is different from a credit card. With a credit card, you borrow money to pay later. With a debit card, you use the money you already have.

There are a few different ways these cards work. Most people use an online debit system. This system asks the bank for permission every time you buy something. You might use a secret PIN to make it safe. This is called PIN authentication. Some cards use an offline system. These cards connect to your bank, but there is a delay before the money moves. There is also an electronic purse system. In this system, the money is stored right on the card's chip.

This allows you to pay even if the machine has no internet connection.

Many different groups manage these card systems. These are often called networks. The five biggest networks are UnionPay, American Express, Discover, Mastercard, and Visa. Different countries have their own special cards, too. For example, Canada uses Interac. France uses Carte Bleue. In China, people use UnionPay. In India, the system is called RuPay. Some of these old national systems have joined together. Many now use the Maestro logo, which is part of the Mastercard brand. This helps people use their cards in different countries.

Cards come in many different shapes and materials.

Most cards are made of plastic. However, some are made of metal. A very small number are even made of wood. Most cards have a small chip on the front. You can tap your card to pay using contactless technology. You can also insert the card into a machine. Many cards also have a magnetic stripe on the back. Some people even use virtual cards. These have no physical shape at all and are only for the internet.

Some people use special prepaid debit cards. These are cards you can reload with more money. They are very helpful for people who do not have a regular bank account. They are also safer than carrying a lot of cash. People use them to stay safe from online fraud. In the United States, some cities like Chicago use them for transit passes. The federal government also uses them to send benefit payments. These cards make it easy to get money without using paper checks. They help many people join the modern world of digital payments.
