A card number validation system ensures the authenticity of credit and debit card transactions by verifying the validity of card numbers.
This system uses the Luhn algorithm to check if a card number adheres to a specific mathematical formula, detecting errors and fraud attempts.
Validation prevents unauthorized transactions, protects cardholders, and reduces the risk of fraudulent activities.
Online retailers rely on card number validation to secure transactions, build trust with customers, and comply with industry standards like PCI DSS.
