How It Works: The Magic Behind the Validation

The tool's core is the Luhn Algorithm, a clever mathematical trick used globally to detect common errors in card numbers. Este é o processo simplificado:

1. Double & Sum: Starting from the right, every second digit is doubled.If doubling gives two digits (like 16), add those digits together (1+6=7).
2. Total Up: Add all the resulting digits (doubled ones and untouched ones).
3. Check the End: If the total ends in a zero (i.e., divisible by 10), the number is valid.Simple yet incredibly effective!

This tool takes you through these steps interactively, making the complex process easy to understand.
