card.io识别哪些卡类型？card.io是否支持识别商家卡？

Question

除了源注释之外,我找不到card.io的文档.

CardIOCreditCardInfo.h文件具有CardIOCreditCardType的枚举.

typedef NS_ENUM(NSInteger, CardIOCreditCardType) {
  /// Deprecated.
  /// @see CardIOCreditCardTypeUnrecognized, CardIOCreditCardTypeAmbiguous
  CardIOCreditCardTypeUnknown __attribute__((deprecated("Use CardIOCreditCardTypeUnrecognized or CardIOCreditCardTypeAmbiguous instead."))) = 0,
  /// The card number does not correspond to any recognizable card type.
  CardIOCreditCardTypeUnrecognized = 0,
  /// The card number corresponds to multiple card types (e.g., when only a few digits have been entered).
  CardIOCreditCardTypeAmbiguous = 1,
  /// American Express
  CardIOCreditCardTypeAmex = '3',
  /// Japan Credit Bureau
  CardIOCreditCardTypeJCB = 'J',
  /// VISA
  CardIOCreditCardTypeVisa = '4',
  /// MasterCard
  CardIOCreditCardTypeMastercard = '5',
  /// Discover Card
  CardIOCreditCardTypeDiscover = '6'
};

card.io是否仅支持Amex,JCB,Visa,Mastercard和Discover的自动卡号提取？

card.io不支持Lowe's,Home Depot或Target等商家卡的卡号提取吗？

卡号提取是否有其他要求,例如卡号需要浮雕？

CardIOCreditCardTypeAmbiguous和Unrecognized仅用于手动输入的卡号吗？

正确.

正确的,条件是某些商家的卡片使用的数字与标准信用卡类型的格式相对应,例如Visa或万事达卡.card.io将识别这些卡.

卡号提取是否有其他要求,例如卡号需要浮雕？

card.io目前只处理传统的浮雕卡片.

CardIOCreditCardTypeAmbiguous和Unrecognized仅用于手动输入的卡号吗？

正确.
