It's exactly as Ms. Bhandari said. It's a big problem, because programs like Nexus are opt in, in a sense, but the pressure to get through the border—the explicit use of the border as a pain point to encourage travellers to sign up for these types of systems—is a problem.
Canada, for example, piloted a program with the Netherlands, one developed by the World Economic Forum. It's basically a digital identity, housed on your phone, with a lot of your passport information and additional social identity verification program information. The idea was to see if that could be used in replacement of a passport, in order to facilitate border crossings. Facial recognition was the technology built into that system. The end vision of that system—it's very explicit—is getting travellers to voluntarily sign up for it to avoid delays at the border, because it gives you access to faster security processing. However, it later becomes available to banks, telecommunication companies and other entities, as well, for similar identity verification programs.
