Room number charge on Saturday

Hello Rabbi,
In some hotels in Israel, it is possible to receive certain things from the hotel, and at the end of the stay, the room number is charged according to the customer's consumption. If on Shabbat I go to the hotel kiosk and ask for a popsicle and it asks for my room number so that it can charge me for this popsicle at the end of the stay, is this an offense on Shabbat?
Best regards,
