我想知道如何仅根据信用卡的号码来判断信用卡的类型。有谁知道确定可靠的方法吗?

另一个api解决方案在rapidapi银行卡位数检查有250K+发行卡类型。
只有一个GET rest api请求，并获得发卡机构信息，如:
{ "bin_number": 535177, "bank": "Finansbank A.S.", "scheme": "MASTERCARD", "type": "Debit", "country": "Turkey" }

这是一个php类函数，通过CCnumber返回CCtype。 此代码不验证卡或不运行Luhn算法仅尝试查找基于本页表的信用卡类型。基本上使用CCnumber长度和CCcard前缀来确定CCcard类型。

public static function getType($CCNumber)

$CCNumber = trim($CCNumber);
$type = 'Unknown';
foreach (CreditcardType::$creditcardTypes as $card) {

信用卡的第一个数字可以用来大致了解供应商:
签证:49、44或47 Visa电子:42、45、48、49 万事达卡:51 美国运通:34 就餐者:30、36、38 JCB: 35
我用jQuery的解决方案:
function detectCreditCardType() {
var type = new Array;
type[1] = '^4[0-9]{12}(?:[0-9]{3})?$'; // visa
type[2] = '^5[1-5][0-9]{14}$'; // mastercard
type[3] = '^6(?:011|5[0-9]{2})[0-9]{12}$'; // discover
type[4] = '^3[47][0-9]{13}$'; // amex
var ccnum = $('.creditcard').val().replace(/[^\d.]/g, '');
var returntype = 0;
$.each(type, function(idx, re) {
var regex = new RegExp(re);
if(regex.test(ccnum) && idx>0) {
returntype = idx;
}
});
return returntype;
}
如果返回0，则未检测到信用卡类型。
“creditcard”类应该添加到creditcard输入字段中。
卡号的前六位数字(包括初始信息信息) 数字)被称为发行者识别号码(IIN)。这些 识别向该卡发行该卡的发卡机构 持有人。其余的数字由发卡机构分配。的 卡号的长度是它的位数。许多发卡机构打印 他们卡上的整个IIN和账号。
基于以上事实，我想保留一段JAVA代码来识别卡片品牌。
样卡类型
public static final String AMERICAN_EXPRESS = "American Express";
public static final String DISCOVER = "Discover";
public static final String JCB = "JCB";
public static final String DINERS_CLUB = "Diners Club";
public static final String VISA = "Visa";
public static final String MASTERCARD = "MasterCard";
public static final String UNKNOWN = "Unknown";
卡前缀
// Based on http://en.wikipedia.org/wiki/Bank_card_number#Issuer_identification_number_.28IIN.29
public static final String[] PREFIXES_AMERICAN_EXPRESS = {"34", "37"};
public static final String[] PREFIXES_DISCOVER = {"60", "62", "64", "65"};
public static final String[] PREFIXES_JCB = {"35"};
public static final String[] PREFIXES_DINERS_CLUB = {"300", "301", "302", "303", "304", "305", "309", "36", "38", "39"};
public static final String[] PREFIXES_VISA = {"4"};
public static final String[] PREFIXES_MASTERCARD = {
"2221", "2222", "2223", "2224", "2225", "2226", "2227", "2228", "2229",
"223", "224", "225", "226", "227", "228", "229",
"23", "24", "25", "26",
"270", "271", "2720",
"50", "51", "52", "53", "54", "55"
};
检查输入的数字是否有任何给定的前缀。
public String getBrand(String number) {
String evaluatedType;
if (StripeTextUtils.hasAnyPrefix(number, PREFIXES_AMERICAN_EXPRESS)) {
evaluatedType = AMERICAN_EXPRESS;
} else if (StripeTextUtils.hasAnyPrefix(number, PREFIXES_DISCOVER)) {
evaluatedType = DISCOVER;
} else if (StripeTextUtils.hasAnyPrefix(number, PREFIXES_JCB)) {
evaluatedType = JCB;
} else if (StripeTextUtils.hasAnyPrefix(number, PREFIXES_DINERS_CLUB)) {
evaluatedType = DINERS_CLUB;
} else if (StripeTextUtils.hasAnyPrefix(number, PREFIXES_VISA)) {
evaluatedType = VISA;
} else if (StripeTextUtils.hasAnyPrefix(number, PREFIXES_MASTERCARD)) {
evaluatedType = MASTERCARD;
} else {
evaluatedType = UNKNOWN;
}
return evaluatedType;
}
最后，效用方法
/**
* Check to see if the input number has any of the given prefixes.
*
* @param number the number to test
* @param prefixes the prefixes to test against
* @return {@code true} if number begins with any of the input prefixes
*/
public static boolean hasAnyPrefix(String number, String... prefixes) {
if (number == null) {
return false;
}
for (String prefix : prefixes) {
if (number.startsWith(prefix)) {
return true;
}
}
return false;
}
