Interface PINPadDeviceSpec

All Superinterfaces:

DeviceSpec

public interface PINPadDeviceSpec
extends DeviceSpec

The PINPadDeviceSpec interface specifies the capabilities and features of a PINPad device. It extends the DeviceSpec interface, providing methods specific to PINPad devices.

This interface allows for querying the capabilities of PINPad devices, including the number of devices supported, whether the device is internal or external, and the support for additional functionalities like generating random numbers and displaying text.

Method Summary

Modifier and Type	Method and Description
boolean	canGetRandom(int logicalID) Checks if the device supports generating random numbers.
boolean	canShowText(int logicalID) Checks if the device supports displaying text.
int	getCounts() Retrieves the count of supported PINPad devices.
boolean	isInternal(int logicalID) Determines if the PINPad device is internal.

Method Detail

getCounts

int getCounts()

Retrieves the count of supported PINPad devices.

Returns:

The number of supported PINPad devices. Returns 0 if none are supported.

isInternal

boolean isInternal(int logicalID)

Determines if the PINPad device is internal.

Internal devices typically have a system-provided UI for password input.

Parameters:

logicalID - The logical ID of the device, usually 1 by default.

Returns:

true if the device is internal, false if external or on parameter error/not supported.

canGetRandom

boolean canGetRandom(int logicalID)

Checks if the device supports generating random numbers.

Parameters:

logicalID - The logical ID of the device, usually 1 by default.

Returns:

true if random number generation is supported, false otherwise or on parameter error/not supported.

canShowText

boolean canShowText(int logicalID)

Checks if the device supports displaying text.

Parameters:

logicalID - The logical ID of the device, usually 1 by default.

Returns:

true if text display is supported, false otherwise or on parameter error/not supported.
