h3. How to simulate a declined payment

h3. How NMI checks for duplicate transaction
A transaction is treated as duplicate when:
* submit same settlement amount using the same credit card within *20 minutes*
h3. No order ID returned
It happens when the result code is *3* or *300*, and any other _un-listed_ response code (e.g. 0)
h3. the card number did not display in the transaction report
It only happens when the submitted card number is more than *19 digit*
h3. Why the transaction is in Pending Settlement _Pending Settlement_ state and never change to Settle? _Settle_?
All of the approved transactions will “always” say Pending Settlement. It’s a difference between US & EU processing banks. In the US, all transactions are “settled” at the end of the day. In the EU though, transactions aren’t really “settled” via a batch. The gateway was originally designed for US merchants, but has expanded into the EU.
