Guest
Type the name in any language. Hebrew, Russian, Arabic, and Greek fill the English names, which you can correct. Known guests drop down as you type — by ID number, phone, email, or name, the most certain match first; pick one to fill this guest's details from the directory.
Contacts & billing
Same as guest 1? Copy what you need.
Add every party of interest and tick one as primary.
ID documents
Cards
Same checks as the user directory: brand from the IIN, Luhn on the
number, and CVV. Number and CVV go into the vault the moment you save,
on the guest's record, or on the booker's when that guest has no email.
