Another Verifly question

[Noesja]

Does the Verifly app produce a barcode or QR-code after completing? Or is the green ✅️ "ready to sail" all you have to show upon embarkation? 

With passport and credit card in hand and boarding pass in the Navigator app are those the four things I need? Or do they want additional paperwork? Specifically interested in embarkation procedure in Rotterdam.

In Rotterdam (boarding Rotterdam), the procedure was - Passport Check - physical passport presented, then Security line, then direct to the Verifly lane.  No paperwork needed (but we did have paper copies, just in case!).

Apart from the initial traffic jam around the passport check area, it was a very quick boarding.
