Muito bom! Obrigado, converti para .NET o código.
Atualizando regex mastercard com BIN 2
/^5[1-5]\d{14}$|^2(?:2(?:2[1-9]|[3-9]\d)|[3-6]\d\d|7(?:[01]\d|20))\d{12}$/
Parabéns pelo código, vai me ajudar em um projeto!
Como eu faço a implementação?
Uma pergunta como a partir do numero da bin do cartão posso puxar o banco emissor do cartão ??
Você deve instanciar a classe e chamar o método estático getBrandByCardNumber passando o numero do cartão que ele ira retorna a bandeira desse numero. Ex:
$cardNumer = '0000000000000000';
$brand = CreditCard::getBrandByCardNumber($cardNumer);
echo $brand;
@FelipeWielewski Obrigado pelo feedback, vou atualizar.
Obrigado!!
