Overview

A CreditCard object represents a physical credit card, and is capable of validating the various data associated with these.

At the moment, the following credit card types are supported:

  • Visa

  • MasterCard

  • Discover

  • American Express

  • Diner’s Club

  • JCB

  • Switch

  • Solo

  • Dankort

  • Maestro

  • Forbrugsforeningen

  • Laser

For testing purposes, use the ‘bogus’ credit card brand. This skips the vast majority of validations, allowing you to focus on your core concerns until you’re ready to be more concerned with the details of particular credit cards or your gateway.

Testing With CreditCard

Often when testing we don’t care about the particulars of a given card brand. When using the ‘test’ mode in your Gateway, there are six different valid card numbers: 1, 2, 3, ‘success’, ‘fail’, and ‘error’.

For details, see ActiveMerchant::Billing::CreditCardMethods::ClassMethods#valid_number?

Example Usage

cc = CreditCard.new(
  :first_name         => 'Steve',
  :last_name          => 'Smith',
  :month              => '9',
  :year               => '2017',
  :brand              => 'visa',
  :number             => '4242424242424242',
  :verification_value => '424'
)

cc.validate # => {}
cc.display_number # => XXXX-XXXX-XXXX-4242
