Yes. I can quote from Ofcom, which is the regulatory agency in Britain, on the kinds of age assurance that could be highly effective. They're at the stage of putting in regulation. They have passed a whole bill about it. They mention face age estimation. You've heard about age estimation. It works by analyzing the features of a user's face to estimate their age, but there's no collection at all of identity. It's done through estimation, plus or minus two years.
That's one of them. There are obviously others.
