Magnetic Stripe

Have you ever seen a card with a shiny black stripe on the back? That stripe is called a magnetic stripe. It is like a secret code that helps the card work properly.

The stripe is made up of tiny metal particles that can hold information, like your name, your card number, and how much money you have in your account. The particles only recognize certain types of cards and can’t hold too much information, but they are still really useful.

When you use your card to buy something, the special machine at the store reads the magnetic stripe to get all of the information it needs. It uses a magnet to read the information and then sends it to the bank to make sure you have enough money to pay for what you want to buy.

So next time you use your card, remember the magnetic stripe is like a secret code that helps your card work properly and lets you buy things you want.
