Validation for credit cards

var ccPatterns = {
  "visa": "^4[0-9]{12}(?:[0-9]{3})?$",
  "mastercard": "^5[1-5][0-9]{14}$",
  "amex": "^3[47][0-9]{13}$",
  "jcb": "^(?:2131|1800|35\d{3})\d{11}$",
  "diners_club": "^3(?:0[0-5]|[68][0-9])[0-9]{11}$",
  "elo": "/^([6362]{4})([0-9]{12})$/",
  "hipercard": "/^(3841\d{10}(\d{3})?)|(3841\d{15})$/"
};

Explanation:

• Visa card numbers start with a 4. New cards have 16 digits. Old cards have 13.
• MasterCard numbers start with the numbers 51 through 55. All have 16 digits.
• American Express (amex) card numbers start with 34 or 37 and have 15 digits
• JCB cards beginning with 2131 or 1800 have 15 digits. JCB cards beginning with 35 have 16 digits.
• Diners Club card numbers begin with 300 through 305, 36 or 38. All have 14 digits. There are Diners Club cards that begin with 5 and have 16 digits. These are a joint venture between Diners Club and MasterCard, and should be processed like a MasterCard.

A regex que estou usando para o Aura por enquanto é: /^50[0-9]{17}$/, é o mesmo que a saraiva usa(andei bisbilhotando o checkout deles eheuehueheuu).
