Hi! I am going on a trip to Budapest in a couple of weeks and need to fill out the Vendégem Application. When I tried to look at the FAQs on their website (https://info.vendegem.hu/en/frequently-asked-questions), nothing would load properly. I was wondering if anybody could help answer a couple of questions

1. In the application, it asks for the Postal code of place of residence, is that referring to the postal code of the Airbnb or the postal code for where I live?
2. I am going on a trip with some family in another country, what would be the best way to fill out the application for them as I dont have their passport to scan. Should I tell them to also download the app and scan their passports or can I scan a picture of their passports?
