Asking for a Tip on the Card Reader
Your merchants can easily ask their guest for a tip using On-Reader Tipping. At the start of each transaction, the guest can be asked if they want to give a tip and then can enter the tip amount directly on the card reader. You can also ask the guest to enter the total amount for the transaction, including a potential tip.
On-reader tipping is currently only available on the Miura card readers. To activate this feature, contact your account manager.
Asking for the Tip Amount
In order to ask the shopper to enter the tip amount, create
MPTransactionProcessTippingStepParameters
 with
tippingAmountParametersWithOptionalsBlock
 and use them to create the
MPTransactionProcessParameters
. Then pass them along as
processParameters
 to
createTransactionViewControllerWithTransactionParameters
:
MPTransactionProcessTippingStepParameters *params =
        [MPTransactionProcessTippingStepParameters tippingAmountParametersWithOptionalsBlock:
                ^(id<MPTransactionProcessTippingAmountStepParametersOptionals>  _Nonnull optionals)
                {
                        [optionals setShowConfirmationScreen:YES];
                        [optionals setFormatWithIntegerDigits:6 fractionDigits:2];
                }];


MPTransactionProcessParameters *pp =
        [MPTransactionProcessParameters parametersWithSteps:
                ^(id<MPTransactionProcessParametersSteps> steps)
                {
                        [steps setTippingStepParameters:params];
                }];


UIViewController *viewController =
        [ui createTransactionViewControllerWithTransactionParameters:tp
                                                                                           processParameters:pp
                                                                                                           completed:/*...*/];
Asking for the Total Amount
In order to ask the shopper to enter the total amount, including a potential tip, create
MPTransactionProcessTippingStepParameters
 with
tippingTotaltParametersWithOptionalsBlock
 and use them to create the
MPTransactionProcessParameters
. Then pass them along as
processParameters
 to
createTransactionViewControllerWithTransactionParameters
:
MPTransactionProcessTippingStepParameters *params =
        [MPTransactionProcessTippingStepParameters tippingTotaltParametersWithOptionalsBlock:
                ^(id<MPTransactionProcessTippingTotalStepParametersOptionals>  _Nonnull optionals)
                {
                        [optionals setShowConfirmationScreen:NO];
                        [optionals setFormatWithIntegerDigits:6 fractionDigits:2];
                }];
    
    
MPTransactionProcessParameters *pp =
        [MPTransactionProcessParameters parametersWithSteps:
                ^(id<MPTransactionProcessParametersSteps> steps)
                {
                        [steps setTippingStepParameters:params];
                }];
         
UIViewController *viewController =
        [ui createTransactionViewControllerWithTransactionParameters:tp
                                                                                           processParameters:pp
                                                                                                           completed:/*...*/];
Getting the Tip Amount
After the transaction has been completed, you can access the included tip amount via the
details.includedTipAmount
 property of the
MPTransaction
 object that you receive as part of the
completed
 block: 
NSLog(@"Included Tip: %@",transaction.details.includedTipAmount);

Asking for the Tip Amount
In order to ask the shopper to enter the tip amount, create
TippingProcessStepParameters
 with
askForTipAmount()
 and use them to create the
TransactionProcessParameters
. Then, pass along the process parameters to
createTransactionIntent
:
TippingProcessStepParameters steps = new TippingProcessStepParameters.Builder()
        .askForTipAmount()
.showConfirmationScreen(true)
 //deprecated way to enable add tip screen
    .showAddTipConfirmationScreen(true) //new way of enabling add tip screen
    .showTotalAmountConfirmationScreen(true) //enable the total amount confirmation screen 
    .maxTipAmount(new BigDecimal(2.0)) // enables the maximum acceptable tip amount check 
        .numberFormat(6, 2).build();

TransactionProcessParameters transactionProcessParameters = new TransactionProcessParameters.Builder()
        .addStep(steps)
        .build();

Intent intent = MposUi.getInitializedInstance().createTransactionIntent(params, 
transactionProcessParameters
);
startActivityForResult(intent, MposUi.REQUEST_CODE_PAYMENT);
Asking for the Total Amount
In order to ask the shopper to enter the total amount (including a potential tip), create
TippingProcessStepParameters
 with
askForTotalAmount()
 and use them to create the
TransactionProcessParameters
. Then pass along the process parameters to
createTransactionInten
:
TippingProcessStepParameters steps = new TippingProcessStepParameters.Builder()
        .askForTotalAmount()
.showConfirmationScreen(false)
 //deprecated way to disable add tip screen
    .showAddTipConfirmationScreen(false) //new way of disabling add tip screen
    .showTotalAmountConfirmationScreen(true) //enable the total amount confirmation screen
    .maxTipAmount(new BigDecimal(2.0)) // enables the maximum acceptable tip amount check 
        .numberFormat(6, 2).build();

TransactionProcessParameters transactionProcessParameters = new TransactionProcessParameters.Builder()
        .addStep(steps)
        .build();

Intent intent = MposUi.getInitializedInstance().createTransactionIntent(params, 
transactionProcessParameters
);
startActivityForResult(intent, MposUi.REQUEST_CODE_PAYMENT);
Both
askForTipAmount()
 and
askForTotalAmount()
 tipping strategies benefit from reader screen configuration when performing the transaction; while
showAddTipConfirmationScreen()
 is used for the first confirmation screen that pops up,
showTotalAmountConfirmationScreen()
 is managing the second confirmation screen that appears when confirming the total amount of the transaction. The screen configuring properties are optional and by default the add tip configuration screen is enabled and the total amount tip configuration screen is disabled. The
maxTipAmount()
 is also optional, and when set is defining the upper limit for tip amounts above which shopper will be asked to enter a lesser amount.
For both tipping strategies, the
showConfirmationScreen()
 method that configures the first confirmation screen for tipping has been deprecated. Instead, you can use
showAddTipConfirmationScreen()
.
Getting the Included Tip Amount
You can access the included tip amount via the
getDetails().getIncludedTipAmount()
 method of the
Transaction
 object: 
System.out.println("Included Tip: " + transaction.getDetails().getIncludedTipAmount());
