payment_card_validation
Have you ever wondered what all those numbers you can never quite memorize stamped across your credit card actually mean?
Obviously, in daily life, we often use our credit cards but most of us have little understanding of the objectives they represent.
That lengthy number on the front of your card is packed with crucial information. The order of the digits isn’t random but strategically organized, following an international standard.
This is a Flutter application that helps us demonstrate how to validate the payment card number, CVV, and date.
