Credit Card Validator

1. What is a credit card validator?

A credit card validator allows anyone to check if a credit card is valid or not. This is made possible using the Luhn algorithm which is used by the banks to create these credit card numbers. The details you can see after putting a credit card number are as follows:

• CARD TYPE - This shows the name of the issuer of the card number such as VISA, MASTERCARD, AMEX etc.
• VALID - It will show you if your given credit card number is valid or invalid.
• LENGTH VALID - There be a case sometimes where the input is just not complete even though to the digit it is correct. If that's the case with your input you will see false here.
• LUHN VALID - This shows if your input follows the Luhn algorithm or not.

All these details are generated for every single card and are random. Every time you click on the generate button a new card is generated with unique details.

2. How to use a credit card validator?

Type the credit card number you want to verify. You will automatically see results as true with the card number issuer name if your input was valid.

3. Are the credit card numbers stored?

No, the input is NOT stored in any case. Every number is gone as soon as you close the tab. There is no way anyone can else see or read the credit card number.
