# Integrating UAE Pass, Tap Payments & Arabic RTL into Mobile Apps: Developer Blueprint
Building digital products for the United Arab Emirates requires specialized localized technical integration. Whether you are engineering a FinTech platform, e-commerce marketplace, or enterprise SaaS portal, your application must meet UAE digital standards: UAE Pass digital identity verification, regional payment processing (Tap / Telr / Apple Pay), and bi-directional Arabic RTL localization.
In this technical guide, the senior architecture team at Wise Hustlers details the implementation steps for these core GCC integration pillars.

1. 🔐 UAE Pass OAuth 2.0 PKCE Integration
Authentication Sequence Flow
1. App Request: User taps "Sign in with UAE Pass".
2. OAuth Authorization: App generates a secure code_verifier and code_challenge using PKCE.
3. Deep Link Redirect: App opens UAE Pass via custom scheme (uaepass://).
4. Biometric Auth: User verifies identity inside the official UAE Pass app via facial scan or PIN.
5. Token Exchange: App receives authorization code via deep link callback (https://yourapp.com/auth/callback) and exchanges it for a signed JWT containing verified Emirates ID details.
