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.
