Selling individual trading cards (singles) is time-consuming to pull and ring out, with very little financial payoff per transaction.

Existing point-of-sale and inventory systems are not designed for the high-volume, low-margin sale of individual cards, requiring manual retrieval and checkout that slows down operations.

App Concept

CardFlow Retail

A streamlined point-of-sale and inventory management system built for card shops that purchase and resell single cards. It integrates barcode scanning for quick lookup, displays real-time location of each card in the store, and automates pricing updates based on market data. Staff can pull and ring out singles in seconds, not minutes.

Key Features

Barcode or SKU-based scanner to instantly identify and price a card
Real-time inventory map showing exact display wall or drawer location
Automatic price updates from market price feeds (e.g., TCGPlayer, eBay)
Quick ring-up with bundled checkout for multiple singles

Target Users: Employees and owners of hobby card shops (e.g., Pokemon, Magic: The Gathering) with a high-volume singles wall and 2-10 staff members.

Revenue Model: $49/mo per store subscription, plus 0.5% transaction fee on singles sold via integrated checkout.
