Payment Features / Card Validation - Android SDK

Intro

The function CardValidation is used to verify if the user has a valid card so that you are more confident a payment can be completed.

How to do a card validation

The following code snippet demonstrates how you can start a card validation request.

    TokenApi tokenService = new TokenService();
    ExternalTerminal terminal = createExternalTerminal();

    TokenDelegate tokenDelegate = new TokenDelegate() {
    ...
    };

    tokenService.validateCard(terminal, tokenDelegate);

the tokenDelegate.onTokenSuccess(TokenResult result) contains the result and the state (SUCCESS/FAILURE) shows you whether the card is valid or not.

Normal Abort After Card Validation

The following code snippet demonstrates how you can do a Normal Abort

    boolean isSilent = false;
    TokenApi tokenService = new TokenService();
    ExternalTerminal terminal = createExternalTerminal();

    TokenDelegate tokenDelegate = new TokenDelegate() {
    ...
    };

    tokenService.abort(isSilent, terminal, tokenDelegate);

The following code snippet demonstrates how you can do a Normal Abort on a new connection

    boolean isSilent = false;
    TokenApi tokenService = new TokenService();
    ExternalTerminal terminal = createExternalTerminal();

    TokenDelegate tokenDelegate = new TokenDelegate() {
    ...
    };

    tokenService.abortOnNewConnection(isSilent, terminal, tokenDelegate);

Silent Abort After Card Validation

The following code snippet demonstrates how you can do a Silent Abort.

    boolean isSilent = true;
    TokenApi tokenService = new TokenService();
    ExternalTerminal terminal = createExternalTerminal();

    TokenDelegate tokenDelegate = new TokenDelegate() {
    ...
    };

    tokenService.abort(isSilent, terminal, tokenDelegate);

The following code snippet demonstrates how you can do a Silent Abort on a new connection.

    boolean isSilent = true;
    TokenApi tokenService = new TokenService();
    ExternalTerminal terminal = createExternalTerminal();

    TokenDelegate tokenDelegate = new TokenDelegate() {
    ...
    };

    tokenService.abortOnNewConnection(isSilent, terminal, tokenDelegate);
