A third-party kiosk application accepts orders and posts them to Simphony using Simphony Transaction Services Gen2 (STSG2). To let a guest pay at the kiosk instead of paying at the time of pickup, a PED is built into the kiosk.

To ensure that the payment is processed for the correct merchant and in the correct Payment Cloud Store, the third-party application sends a payment request to the Payment Cloud PED associated with or built into the kiosk and then receives the response to include it in the STSG2 post.
