Chekin automates guest data collection and sends it to SEF (Serviço de Estrangeiros e Fronteiras) on your behalf, through the SIBA portal. This guide covers activation from the Amenitiz Marketplace and setup on the Chekin side.

This article applies to properties in Portugal 🇵🇹.

Data sync — bookings and guest contact details flow from Amenitiz to Chekin automatically.

Legal compliance — SIBA/SEF submissions from a single interface.

Guest self check-in — guests enter ID details on their phone, by photo or manual entry.

Automated submissions — Chekin sends guest data to SEF nightly at 11 PM.

1. Open the Amenitiz admin area and go to Marketplace. Search for Chekin.

2. Click Activate.

3. Enter your email and password.

4. Select Hotel or Vacation Rental based on your property.

Once activated, you are redirected to www.chekin.com. Log in with the credentials you just set.

1. Go to the Properties tab and click your property name.

2. Property Info — check every field is filled, then click Save Changes.

3. Online check-in — toggle Send online check-in to guests automatically and pick when the form is sent (when the reservation is created, 24h before check-in, etc.). Click Save Changes.

4. Legal — connect to the SIBA (SEF) portal:

• Toggle Activate the automatic sending of guest data to your police account.

• Enter your SIBA credentials:

— Username: your Unidade hoteleira number

— Password: your Chave de autenticação

— Establishment number: usually 0

• Click Save Changes.

Open the Bookings tab to follow guest data completion. Each guest shows a status:

☑️ Completed — all guest data was collected and sent to SEF.

👮 Incomplete / On hold — some fields are missing; Chekin cannot submit.

If guests have not filled the form, resend it by email from Chekin or copy the link and share it through your own channels. 👇

If the automatic 11 PM submission did not go through, open the reservation, go to Police (Check-in), and click Send manually. 👇

In your SIBA profile, set Método de Envio to Página no Portal. If it is set to Web Services, data may not reach SEF.

Once a guest completes the form in Chekin, you can pull their details into Amenitiz. See: How to fetch guest information from Chekin.

Can I sign up directly on chekin.com?

No. The integration only works if the account is created from Amenitiz → Marketplace → Chekin → Activate.

Can I change the property type later (Hotel ↔ Vacation Rental)?

No. Delete the Chekin account and activate it again from the Amenitiz Marketplace.

Which SIBA credentials do I need?

The Unidade hoteleira number (Username), the Chave de autenticação (Password), and the establishment number (usually 0). You get these when you register in SIBA.

I have more than one account in SIBA — which property type should I pick?

Select Vacation Rental (Holiday Rental) when creating the Chekin account.

At what time does Chekin send guest data to SEF?

Nightly at 11 PM (local time).

My data is not reaching SEF — what should I check?

Confirm Método de Envio in SIBA is set to Página no Portal, not Web Services.

I use Nuki or another digital key — can I connect it through Chekin?

Contact Chekin support directly. The team will confirm which digital key systems can be integrated.
