RAZN NFC
NFC Companion App for Instant Real-World Connections
RAZN is the official iOS companion app for RAZN ReTag NFC products. The app enables users to program NFC tags with websites, social profiles, payment links, portfolios, reviews, and other URLs in seconds.
Users simply save their frequently used links, tap "Write", and hold their iPhone near an NFC tag. Anyone who taps that tag can instantly open the associated destination on their phone.
The Problem
Most NFC writing applications are built for technical users and require multiple steps to configure a tag. For creators, freelancers, and small businesses, updating and sharing the same links repeatedly is time-consuming and unnecessarily complex.
The Solution
RAZN provides a streamlined, consumer-focused experience for programming NFC tags:
One-tap NFC link writing
Quick-save link presets for frequently used URLs
URL normalization and reliable NDEF formatting
Integrated sharing workflow
Native iOS experience optimized for speed and simplicity
