Guest registration without the paperwork.

Meldefein brings guest registration, visitor's tax and a digital guest guide together. Your guests enter their details on their own phone before arrival; you only check them. So that hosting has more to do with guests again than with forms.

The problem

The registration form comes back with every guest.

Every arrival brings the same obligatory work: fill in the form, transfer the data, settle the visitor's tax, file it. Quick enough one at a time — over a year it becomes a stack that eats up time and patience.

Meldefein turns that procedure into a digital one that repeats itself — instead of walking through it by hand every time.

Optional on site · guest terminal

A welcome that stays.

The guest guide gets a fixed place in the flat. The guest terminal with a touch screen greets your guests by name and shows what matters in a portrait view. Anyone who prefers their own phone scans the QR code and gets the same guest guide in the browser. Try both right here.

  • Wi-Fi and house information at a glance

    Heating, rubbish, departure and the Wi-Fi each have a fixed place. Fewer questions on the evening of arrival.

  • Your recommendations, not just any

    Places to visit, your favourite café, notes on the guest card: you decide what your guests see. Weather and the tip of the day follow the location of your flat.

  • It works without the terminal too

    The guest link and the guest guide work without a device. Whether the terminal suits your flat is something we discuss in person; equipment and availability on request.

What Meldefein does

Set it up once, then it runs

Not another booking system, but a lean helper for the obligations around it.

Pre-check-in

A link instead of a slip of paper

The guest enters their details on their own phone before arrival. You only check them instead of typing up forms.

Electronic reporting

To the right authority, without detours

The guest report goes via the AVS interface to where it has to go. It requires a cleared connection for your municipality.

Visitor's tax & guest guide

Billing and information in one place

Stays, nights and visitor's tax details are kept together as a working basis for your settlement with the municipality. Guests open the Wi-Fi, house information and your recommendations in the browser.

Trust

Guest data should be protected — not collected.

Registration forms contain personal data about your guests. Meldefein handles it as sparingly as the obligation allows — and no further.

  • Only the data the registration obligation requires. Processing in the EU, with clear deletion periods.
  • No tracking, no passing data on for advertising. The data serves the registration — nothing else.
  • You stay in control: you see what is reported — and you remain responsible for it.

Administration should barely be felt. The time belongs to the guests, not to the registration form.

— Thomas Theobald, founder of Theobase GmbH

Where it stands

The connection is in place. Now come the first hosts.

The test series against the AVS registration web service ran through completely and without errors, and Meldefein is registered and cleared with AVS as software. Bad Säckingen is the first connected local tourist authority.

Meldefein runs in our own holiday flat with real arrivals. New hosts start with personal support and, for now, with an invitation code. That way it shows where everyday use still catches before Meldefein opens to everyone.

Getting started

Let's get to know your flat.

I support the start personally: setup, clearance with your local tourist authority and the question of whether a guest terminal suits you. There are only a few places.
