Age assurance is fast becoming a crucial compliance requirement as global regulations around online safety and data privacy tighten. Yet, meeting these regulatory demands shouldn’t mean compromising on your players’ authentic in-game experience.

The real challenge is this: how do you design age assurance that’s fully native — customised to your app’s UX, matches your brand’s look and feel and avoids frustrating moments like forcing players to jump through bolted-on or disruptive screens? The best age assurance experiences feel integral to your game, are intuitive, mobile-first, and completely branded as part of your mobile game.

This article explores how k-ID’s AgeKit+ enables fully native age assurance that unlocks compliance, engagement and user confidence for every mobile game publisher.

Fully Optimised for Native Mobile UX

Our age verification flows are fully optimised for any screen layout your game works best in — portrait, landscape, immersive modes. The interface automatically adapts to the user’s device orientation, avoiding users needing to rotate their mobile repeatedly and preventing user frustration with awkward flows.

ID Verification — Mobile View

This thoughtful UX design creates a smoother, more immersive verification flow for users in these environments. Optimised for mobile, AgeKit+ offers fast and frictionless age verification with short flows and minimal steps.

Customise Your Branding

Compliance Studio gives you full control to customise colours, fonts, icons, and other visual elements so that your age assurance flow truly reflect your brand’s identity. This co-branding capability makes the verification process feel like a natural extension of your game, not an intrusive third-party workflow — building player trust and reducing abandonment during the process.

👉 Explore how you can set custom branding for your age assurance flows using the interactive demo below.

Seamless Compliance

AgeKit+ allows you to customise and combine multiple verification methods tailored to the type of service and your assessed risk profile. This approach makes our age assurance inclusive and choice-driven, letting players choose what they find easiest and most comfortable.

Example Age Verification Methods — Mobile View

Some of the core methods we support are briefly explained below.

🧑‍🦱✨ Facial Age Estimation

k-ID provides world-class, on-device and server-side facial age estimation (FAE) technology, complete with a variety of anti-spoofing measures — including active liveness checks, screen and device edge monitoring, face swap detection, and detection of a virtual camera. This technology holds the Age Check Certification Scheme (ACCS) EAL3 certification level.

The unique feature of the technology is that it conducts FAE entirely on-device, meaning no biometric data ever leaves the user’s device. It’s privacy-preserving by design, and avoids sharing sensitive personal data with external servers.

🔑 Users can verify once and re-use it across different platforms

AgeKey is an anonymous age credential bound to a FIDO passkey on the user’s device. While traditional systems asks the user to prove their age every time they want to access restricted content or services, AgeKey is created once and stored locally on the user’s device, where it can be reused anywhere that supports it.

🪪 ID Scan

k-ID supports a comprehensive range of legitimate government-issued ID document worldwide, including passports, driving licences, residence permits, national identity cards, etc. The advanced scan technology leverages OCR and AI-enhanced data extraction combined with proprietary data interpolation for high accuracy. Optionally, you can add a face match step comparing the ID photo with a live selfie for enhanced verification.
