Gets the billing address associated with buyer's payment card.

Note this billing address will only be populated when billing address is set as required through CardRequirements.Builder.setBillingAddressRequired(boolean). Also, the billing address' appearance depends on the optional setting in CardRequirements.Builder.setBillingAddressFormat(int)

Gets the card class which can be either credit, debit or prepaid. See WalletConstants.CardClass for the expected card class values. This class should not be displayed to the buyer, but can be used when the details of a buyer's card are needed. An example would be selecting a processor that gives better interchange rates or applying a discount depending on the card class.

Gets a user-facing message to describe the card selected for funding this payment transaction. You are required to show this to inform the buyer of their funding source. Please refer to the documentation for more information.

IMPORTANT: Do not attempt to parse the contents of this string as the format, contents and length may change at any time. If you need finer grain details, see getCardNetwork(), getCardDetails(), and getCardClass() for stable card information.

Gets the last four digits of the selected card. These details should not be displayed to the buyer, but can be used when the details of a buyer's card are needed. An example would be for customer support to help the buyer identify the card used for this transaction.

Gets the card network of the selected card. Card network has a finite set of values. This card network should not be displayed to the buyer, but can be used when the details of a buyer's card are needed. An example would be for customer support to help the buyer identify the card used for this transaction.

You can rely on the card network not changing once it is defined for a given card in a transaction (i.e. purchasing with a single Visa card will always return VISA).

Examples of currently expected values for elements returned are:

• VISA
• MASTERCARD
• DISCOVER
• AMEX
