Embedding customer identity verification into your existing app — rather than standing up a separate identity product — is faster, cheaper, and better for your users. Here’s why the SDK approach wins, and how BlueKee makes it work.
Many businesses we talk to has the same starting point: an existing mobile app their customers already use. It might be a banking or fintech app, a loyalty and rewards platform, an insurance portal, a utilities self-service tool, or a healthcare patient app. The app works. Customers use it regularly. And now the business needs to verify who those customers actually are — to comply with regulations, prevent fraud, or unlock higher-trust features.
The instinct is often to bolt on a third-party identity flow that redirects users out of the app, or to build an entirely separate verification product. It sounds logical. Identity is sensitive. It deserves careful handling.
But redirecting your customers out of your app is one of the fastest ways to lose them. Every handoff to an external tool is a drop-off point — and drop-off is expensive.
The hidden cost of friction in customer identity
When businesses add customer identity verification via a standalone flow or a separate app, they’re not solving one problem — they’re creating another. Your customer is mid-journey in your app when suddenly they’re redirected to an unfamiliar interface, asked to re-enter information, and handed back when the check is complete. At every one of those transition points, some percentage of customers abandon.
For regulated industries — financial services, healthcare, insurance, utilities — this isn’t just a conversion problem. It’s a compliance problem too. Identity verification that isn’t tightly integrated into the product journey is harder to audit, harder to monitor, and harder to enforce consistently.
"The best customer identity experience is one your customers never notice — because it lives seamlessly inside the app they already trust."
Beyond the customer experience, there’s the engineering overhead. A separate identity product requires its own authentication layer, its own credential storage, its own update lifecycle, and its own support queue. For what? A capability that works better — and converts better — when it lives natively inside your existing product.
What “embedding” customer identity actually means
Embedding identity verification means integrating the entire credential issuance, verification, and presentation flow directly into your existing mobile app — without rebuilding your app from scratch. Your customer never leaves the experience they know. They get push alerted to your app, verify their identity and get on with their day.
This is made possible by a Software Development Kit (SDK) — a set of pre-built components your development team integrates into the existing app’s codebase. The SDK handles the complex parts: the cryptographic signing of credentials, the secure storage, the verification flow, and the compliance logic. Your team wires it in; BlueKee’s SDK does the heavy lifting underneath.
The same capability extends naturally to your own workforce too. Businesses that use BlueKee to verify customer identities can apply exactly the same infrastructure to issue and verify staff credentials — making it a dual-purpose investment. But for most of the organisations we work with, the customer identity use case comes first, and employee credentialing follows as a natural extension.
WHAT THE BLUEKEE SDK HANDLES
Customer identity verification and onboarding, credential issuance and lifecycle management, cryptographic signing and tamper-proofing, offline verification (no internet required on-site), revocation and expiry logic, audit trail generation, and multi-format ID presentation — all via a clean mobile SDK for iOS and Android. Works for customer-facing flows and internal employee credentialing alike.
Build vs embed: a direct comparison
| Approach | Time to deploy | Customer experience | Maintenance burden | Integration with existing workflows |
|---|---|---|---|---|
| Build a new standalone app | 6–18 months | Poor — another app to install and manage | High — separate lifecycle | Minimal — disconnected from existing tools |
| Redirect to a third-party identity flow | Weeks to months | Friction-heavy — customers leave your app | Medium — vendor dependency | Limited — generic, not context-specific |
| Embed via BlueKee SDK | Days to weeks | Seamless — never leaves your app | Low — SDK updates automatically | Full — lives inside your existing flows |
How the integration works
The BlueKee SDK is designed to integrate with minimal disruption to your existing codebase. Here’s a high-level view of what the process looks like for most teams:
- SDK installation
Add the BlueKee SDK package to your iOS or Android project. It’s distributed via NPM package so your developers work within their existing toolchain. - Wire in the UI components
Drop BlueKee’s pre-built UI components into your app’s navigation and customise the components to match your existing design system perfectly. - Connect your enterprise systems
BlueKee connects to your existing enterprise systems via our APIs to allow you to trigger identity contract requests, receive identity contract results and to interact with our systems. - Configure your identity contracts
Define the identity contracts that suit your use case — from live biometric checks to document-based verification of name, date of birth, and more. BlueKee’s dashboard lets your team configure exactly what each verification moment requires. - Go live
Push your updated app. Your existing users get the new identity verification capability in their next app update — no new download, no new account, no training required.
What your customers — and your staff — experience
From a customer’s perspective, embedded identity verification via the BlueKee SDK feels like a natural part of using your app. When a verification moment is triggered — opening a new account, upgrading to a premium tier, accessing age-restricted content, or completing a high-value transaction — the customer receives a push notification into your app, verifies their identity within the experience they already know, and continues on their way. No redirect. No separate login. No confusion about whose app they’re even using.
Consider a few real scenarios: a financial services app that needs to verify identity before issuing a credit product; a healthcare platform that must confirm a patient’s identity before sharing medical records; an insurance portal unlocking claims submissions; a utilities company verifying the account holder before processing a high-value service request. In every case, the identity moment happens inside the app — not outside it.
No redirects to third-party verification portals. No abandoned journeys. No customers who gave up halfway through. Just a verified, tamper-proof digital credential delivered inside the app your customers already trust.
For your employees, the experience is equally clean. Staff receive their digital credential inside the same app or workforce tool they use daily. On a construction site, a worker shows their verified credential to a site supervisor. At a government building, a staff member presents it at the entrance. At a service desk, a technician confirms identity before accessing a sensitive system. Same SDK, same infrastructure — a natural extension of the customer identity capability you’ve already deployed.
In-app, end-to-end
Customers verify identity without ever leaving your app — no redirects, no third-party screens, no broken brand experience.
Push-triggered verification
Trigger identity checks via push notification at exactly the right moment in the customer journey — no manual prompting required.
Works for staff too
The same SDK that verifies customers can issue and verify employee credentials — one integration, dual purpose.
Audit trail built in
Every verification event is logged automatically — essential for regulated industries and compliance reporting.
The bottom line
Customer identity verification is most powerful when it’s invisible. And invisible means it happens inside your app — not in a redirect, not in a separate tool, not in a flow your customer has to context-switch to complete.
The BlueKee SDK exists for exactly this reason: to let businesses add verified customer identity to the apps they’ve already built, the platforms their customers already use, and the moments in the journey that actually matter. No friction. No drop-off. Just a verification experience your customers complete — and a credential your business can trust.
If your team is evaluating how to bring customer identity verification into your product without starting from scratch, the SDK approach is almost always the right answer — and BlueKee is built specifically to make that integration as clean and fast as possible. Your staff credentialing needs are covered by the same integration, at no extra development cost.
