    int transactionHost
)

protected abstract function BeginEftTransactionImpl (
    pinpadSystem : PinPadSystem, 
    transactionHost : int

Parameters

  • pinpadSystem
    Name of the desired PIN Pad Management System.
  • transactionHost
    Identifies the EFT Transaction Host to be used for this transaction.

Remarks

The PinPadBase class calls BeginEftTransactionImpl from its BeginEftTransaction method. BeginEftTransactionImpl must be implemented by the service object to place the PIN pad device in EFT Transaction Mode. Before calling the BeginEftTransactionImpl, the PinPadBase class ensures that the following is true:

  • The PIN pad device has been opened, claimed, and enabled;

  • The PIN pad isn’t already performing an EFT transaction; and

  • The value specified for the pinpadSystem parameter exists in the PinPadSystem enumeration.

If these validations succeed, the PinPadBase class calls BeginEftTransactionImpl. If any of the above conditions aren’t met, the PinPadBase class throws an exception.

The service object should check to ensure the transactionHost parameter specifies a transaction host that is supported.

BeginEftTransaction may cause a PosControlException to be thrown with the following ErrorCode:

Value

Meaning

Illegal

One of the following conditions has occurred:

  • The requested PIN Pad Management System is not supported by the service object; or

  • The requested EFT Transaction Host is an illegal value for the selected PIN Pad Management System.

Busy

The PIN pad device is already performing an EFT transaction.
