I need the Regex to detect when the credit card banner is Hipercard, Aura and Elo.
I already have regexes for Amex, Martercard, Diners Club, Visa, Discover and JCB:
Visa: ^4[0-9]{12}(?:[0-9]{3})
Mastercard: ^5[1-5][0-9]{14}
Amex: ^3[47][0-9]{13}
Diners Club: ^3(?:0[0-5]|[68][0-9])[0-9]{11}
Discover: ^6(?:011|5[0-9]{2})[0-9]{12}
JCB: ^(?:2131|1800|35\d{3})\d{11}
Credit card numbers follow an international standard called IEC-7812 .
Basically, the first six digits of the card are the Issuer identifier number (IIN).
So you do not need a regex, but an IIN list with which you can check the number.
Who cares, a list of BINs follows:
| Bandeira | Comeca com | Máximo de número | Máximo de número cvc |
| ---------- | ------------------------------------------- | ---------------- | -------------------- |
| Visa | 4 | 13,16 | 3 |
| Mastercard | 5 | 16 | 3 |
| Diners | 301,305,36,38 | 14,16 | 3 |
| Elo | 636368,438935,504175,451416,509048,509067, | | 3(?)
| | 509049,509069,509050,509074,509068,509040,
| | 509045,509051,509046,509066,509047,509042,
| | 509052,509043,509064,509040 | |
| | 36297, 5067,4576,4011 | 16 | 3
| Amex | 34,37 | 15 | 4 |
| Discover | 6011,622,64,65 | 16 | 4 |
| Aura | 50 | 16 | 3 |
| jcb | 35 | 16 | 3 |
| Hipercard | 38,60 | 13,16,19 | 3 |

/^((((636368)|(438935)|(504175)|(451416)|(636297))\d{0,10})|((5067)|(4576)|(4011))\d{0,12})$/
Hipercard:
/^(606282\d{10}(\d{3})?)|(3841\d{15})$/
HiCard:
/^(606282\d{10}(\d{3})?)|(3841\d{15})$/
For those who wanted a simpler way to deal with a large number of cards, I recommend using the% Credit Card Type% Credit Card Type to identify the banner of the card by its number.
In ES6:
import creditCardType from 'credit-card-type'
creditCardType(cardDetail.number).filter((card) => {
return card.type
})
