To handle alcohol sales at the kiosk, mark the items for which guests should be prompted to confirm their age. To do this, in the dish properties, insert the value {"isAlcohol": true} into the extended property itemParams.
If you need to specify several characteristics in the itemParams property, list them separated by commas, for example: {"imgScale":0.85, "isAlcohol":true}.

Peculiarities of work:

When selecting one or another Kiosk Operation Type in the service menu (Basic Settings > Kiosk Operation Type), working with alcohol will have its own characteristics:

• Type of operation – payment at the kiosk – alcoholic products are not displayed on the kiosk screen.
• Type of operation – payment at the cash register – alcoholic products are displayed on the kiosk screen. When adding alcohol to the basket, a warning message appears.
• Type of operation – payment at the kiosk or at the cash register – alcoholic products are displayed on the kiosk screen. When adding alcohol to the cart, a warning message appears. The option to choose payment at the kiosk is disabled.
  

Combo dish with an alcoholic combo component

• If the mode is set to Payment at the Kiosk, such a combo will not appear in the list of dishes; it will not be available at the kiosk.

• If the mode is set to Payment at Cash Desk or At Both Kiosk and Cash Desk, then the combo dish will be included in the list.

• If an alcoholic combo component is selected, the kiosk screen displays a warning message and disables payment functionality (for mixed mode). 

• If non-alcoholic combo components are selected, no warning message is displayed and there are no payment restrictions.
