Initiate a Refund

Initiate a Refund with a Reference Data of the original Service

When a Refund is performed, the sale system or the device control (eg. the MerchantApp) may provide Refund Reference Data as a reference to the original Service being refunded.

• Refund Reference Data may be identical to the Reference Data of the original Service, but this is not mandatory and not checked.

• Refund Reference Data is not used to retrieve the transaction data of the original Service, but it is stored in the transaction database for the Refund.

Refund Reference Data (optional) : DF59

Steps Taken For this Bulletin:

• A Tag DF59(Refund Reference Data) was added to nexofast.h

• Refund reference data has been included in the Original Transaction section of AcceptorAuth and CompletionAdvice.

As this tag is optional, a check is done on the latter. If the Tag is absent, the original transaction section is not included.

Below is an example derived from a refund of an original transaction.

TlvTree originalTransaction = paymentParams.AddChild(ArkosTags.OriginalTransaction);
originalTransaction.AddEMVDate(ArkosTags.TransactionDate, cal.get(Calendar.YEAR) % 100, cal.get(Calendar.MONTH) + 1, cal.get(Calendar.DAY_OF_MONTH));
originalTransaction.AddEMVTime(ArkosTags.TransactionTime, cal.get(Calendar.HOUR), cal.get(Calendar.MINUTE), cal.get(Calendar.SECOND));
originalTransaction.AddBin(ArkosTags.LocalTimezone, utcOffset);
originalTransaction.AddAscii(ArkosTags.RefundReferenceData,"1234567890");
originalTransaction.AddEnum(ArkosTags.SelectedService, PaymentServiceID.Payment);
