PostcardOTP: Secure Address Verification Platform
Mohamad Ali
Overview
PostcardOTP was developed to solve a common problem for modern businesses: secure and reliable address verification. Traditional methods often lack scalability, branding flexibility, and integration options. To bridge this gap, we created a fully branded platform that leverages OTP-based verification, robust APIs, and customizable pricing models.
Tech Stack: Node.js, React (Vite), REST APIs, secure OTP delivery.
The Challenge
Many companies struggle with:
Verifying customer addresses securely and quickly.
Lack of branded solutions that enhance trust.
Manual verification methods slowing down onboarding.
