TravelTalkOnline Forums Travel and Vacation Forums British Virgin Islands BVI entry on line requirement?

The Roadtown Fast Ferry pointed me at the QR code for the form when I was getting on the boat in St. Thomas. Filled it out, but I have no clue why. The customs guys in Road Town were wholly uninterested in the fact that I had done so. I guess it's more efficient as it's less paper for them to throw out.
