How to recognize a fake credit card?

Introduction

Have you ever wondered if your credit card number is valid or not? There is actually a trick to determine the validity of your credit card number based on a specific algorithm. By following a simple process of adding and doubling numbers, you can ensure the security of your financial information. Here's how it works:

Start by adding the credit card numbers from the right side, doubling every other number before adding it to the total sum. Once all the numbers are added, divide the final sum by 10. If the result is directly divisible by 10, then your credit card information is likely safe. However, if the result is not divisible by 10, it could indicate that the credit card number is invalid or fake.
