Integrate with fysical payment terminal. We do not always have credit card information from clients booking trough a OTA. At arrival they have to pay citytax and it's not possible trough the operator right now.
With a payment terminal integration 100% of our guest can make use of the self check-in

As french grammar is very particular and the actual generic welcome message "bienvenue à/au" does not look appropriate, it would be perfect if the property could write the full welcome message.

In profiles. I don't know if this is where I should send it.

the check-in would be easier and faster

The guests there bill has to stand on fully- paid before they can check in threw kiosk. Give the hotel the oppurtunity to choose if this is necessary. (excluding city tax, for example)

As the italian police requires the "Document issued by" <Country> it would be great to add this field, as mandatory, in the Operator (Kiosk)

If the reservation is for 10 people, once they enter the passport information af all the adults, they can create 10 keys for the apartment. We would like you to introduce an option in Mews where the hotel manager could limit the number of keys that the client can cut at the kiosk.

usage of kiosk without “lock screen”, to allow to show other things on the tablet as well (i.e. usage of ****** check-in robot)

Mews Operator kiosks are a great way to provide your guests with a self-service check-in. However, as some guests may arrive early, Operator kiosks would be a great place to upsell early arrival or late departure options for an additional fee.

As guests are checking-in using Mews Operator, sometimes there may be alternate spaces available for an additional price. In this case, a new feature could allow properties to upsell these spaces so that guests can then choose a higher space category before they complete their check-in.
