The settings on this page prepare a machine for Spark External Settlement, where your server completes or cancels a transaction that was authorized directly on the terminal. Most attribute groups need no change to support this feature.

​
MDB

The MDB Flags setting tells the server which payment flow the device supports:
  • Pre-Authorization is used when the transaction starts before the consumer chooses a product or service and before the final amount is known. Set MDB Flags to * Flags Disabled.
  • Pre-Selection is the flow used when the price is known when the card is presented. Set MDB Flags to 02 PreSelection Enabled.
MDB Flags set to Flags Disabled for the Pre-Authorization flow

​
VPOS Touch

The VAS configurations setting is optional for External Settlement. You can add an indication that the machine performs Spark External Settlement. This is not required for the flow to work and is only for management purposes.
Spark External Settlement cannot coexist with any other Spark flow (Remote Start, Device Start, or Device Stop) on the same machine.
After you finish, click Save to store the configuration.
