iProov’s Web SDK is pushing the boundaries of what is possible with web technologies today. The Web SDK provides a widely available, usable product that forms part of a system that delivers a number of social benefits to society, from remote onboarding to banks and healthcare to safe authentication for national infrastructure and services. Our vision is to provide this experience with native‑level performance across the broadest range of devices possible.

As with any interactive experience on the web, we know this is a challenging environment in which to deliver an SDK: it needs to fit into our customer’s app framework and work in a variety of configurations; it’s a rewarding feeling when we thread the needle through and watch how our releases perform on our dashboards and monitoring systems.
