Cashless payment Saeco Phedra

[AlexNorth]

Hey! We use different coffee machines for vending (coffee corner). Now switched to Saeco Phedra Evo. There is a problem with setting up card acceptance. it is necessary that the client first chooses a drink, and then pays with a card. in other devices in the MDB setup, I simply select always idle (feature level). Always idle is a special mode in the MDB protocol that allows you to start a cashless payment session immediately by selecting a product. But I could not find such an item in Saeco. Can you tell me if Saeco implemented the beginning of the payment session in a different way ???
