This constraint ensures that a credit card number is valid for a given credit card company. It can be used to validate the number before trying to initiate a payment through a payment gateway.

To use the CardScheme validator, simply apply it to a property or method

AMEXCHINA_UNIONPAYDINERSDISCOVERINSTAPAYMENTJCBLASERMAESTROMASTERCARDVISAFor more information about the used schemes, see Wikipedia: Issuer identification number (IIN).

The message shown when the value does not pass the CardScheme check.
type: mixed default: null
2.6 新版功能: The payload option was introduced in Symfony 2.6.
This option can be used to attach arbitrary domain-specific data to a constraint. The configured payload is not used by the Validator component, but its processing is completely up to.
For example, you may want to used several error levels to present failed constraint differently in the front-end depending on the severity of the error.
