credit-card - card.io 可以识别哪些卡类型？ card.io 是否支持识别商户卡？

Question

除了源评论之外，我找不到关于 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 不支持为 Lowe's、Home Depot 或 Target 等商家卡提取卡号吗？

卡号提取是否有其他要求，例如卡号必须浮雕？

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

Answer 1

来自card.io的戴夫在这里。

Does card.io only support automatic card number extraction of Amex, JCB, Visa, Mastercard, and Discover?

正确的。

Does card.io not support card number extraction for merchant cards like Lowe's, Home Depot, or Target?

正确，但附带条件是某些商家的卡使用与标准信用卡类型(例如 Visa 或万事达卡)格式相对应的数字。 card.io 会识别这些卡片。

Are there any other requirements on card number extraction, such as the card number having to be embossed?

card.io 目前仅处理传统的浮雕卡片。

Is CardIOCreditCardTypeAmbiguous and Unrecognized only used for manually-entered card numbers?

正确的。
