🪙 COINFINITY: NFC‑Enabled Coin Stackers for the Future of Collecting

🚀 Project Overview

COINFINITY is a revolutionary modular storage system that combines physical coin collecting with digital NFC technology, making it easy to track, organize, and showcase your collection with style and smarts. Our system uses 3D-printed stackable tubes and embedded NFC tags to give each coin stack a digital identity — scannable with any modern smartphone using our free app.

Makerworld - COINFINITY Crowdfunding launch!

What began as a personal quest for smarter storage has grown into a full-fledged ecosystem, with collectors around the world asking for kits, digital files, and tracking tools. With your support, we can bring this vision to life at scale — with better app features, more stacker sizes, and NFC kits for DIYers.

🎯 Why COINFINITY Is Unique

Smart Storage: Each 3D-printed tube embeds a 25mm NFC tag, allowing users to scan a stack and instantly view the coins it contains via our COINFINITY mobile app.
Modular Design: Mix-and-match stackers support different coin diameters (17.2 mm to 45 mm+).
Digital Meets Physical: Connect your physical collection to a digital record — perfect for organizing, showcasing, or even selling coins in the future.
Open Source Roots: Our coin library is open source and community-powered. Anyone can contribute to expand the database.
Eco-Friendly: Biodegradable PLA. Just download, print, stack and track.
