Do you have lots of contacts or groupings of contacts?
This feature will allow visitors to find folks based on their department. If you have multiple businesses in your building, such as a co-working space, you can leverage the department attribute to group contacts by what makes the most sense for your situation (e.g. their company name, suite number, etc)!
You can input this information either when you add or import contacts, or by editing their info individually on the Contacts page:
What happens if a contact doesn’t have a department assigned?
If you add this to some but not all contacts, any whose department is left blank will not appear on your contact list on the iPad. This is a way to have semi-private contact selection, in the case where you don't want your CEO to appear on the list but they can be found by searching their name specifically.
To activate this feature, update your Receptionist app to version 4.0.9 or later from the App Store.
