setContactKernelAppData

Loads application-specific configuration data into the contact EMV kernel.

This method configures the contact EMV kernel with application-specific parameters and settings contained within a TypeParameterModal object. The configuration data includes Application Identifier (AID) information, transaction limits, terminal capabilities, and other EMV parameters required for contact chip card transaction processing.

Prerequisites:

• EMV kernel environment must be initialized via initializeKernelEnvironment

• This method is part of the contact application data loading sequence

Usage sequence: This method is part of a multi-step contact application configuration process:

1. Call this method one or more times to load application configurations

2. Call endContactKernelAppDataLoad to finalize and commit all loaded configurations

Thread safety: This method should be called from a single thread during the application data loading sequence to ensure data consistency and prevent configuration corruption.

Exceptions: This function MUST NOT throw any exception. Any error must be indicated through NexusRet Any unexpected error must be mapped as NexusRet.INTERR

Implementation notes:

• Validate configuration data format and completeness before processing

• Log detailed information about each application configuration loaded

• Ensure proper error handling for malformed or invalid configuration data

• Consider implementing validation for required EMV parameters

val contactAppConfig = TypeParameterModal(
    aid = "A0000000041010",
    // ... other configuration parameters
)

val result = emvPort.setContactKernelAppData(contactAppConfig)
if (result == NexusRet.OK) {
    // Configuration loaded successfully
    println("Contact application configuration loaded successfully")
} else {
    // Handle configuration loading failure
    println("Failed to load contact application configuration: $result")
}

// After loading all configurations, finalize the process
emvPort.endContactKernelAppDataLoad()
