Case Study: HobbyScan — Building the Operating System for the Hobby
From AI-powered identification to inventory, valuation, grading, commerce, POS, live selling, payments, and events — Doejo helped transform HobbyScan into a technology platform connecting the entire hobby ecosystem.
From Card Scanner to Complete Hobby Platform
HobbyScan began with a powerful idea: make identifying and valuing trading cards dramatically faster.
What started as an AI-powered card scanning experience has grown into something much bigger.
Doejo has helped design and engineer a connected technology ecosystem that brings together collectors, dealers, hobby shops, breakers, marketplaces, grading workflows, events, and payments in a single platform.
Today, HobbyScan connects the entire journey:
Identify → Value → Pre-Grade → Grade → Inventory → List → Sell → POS → Live → Pay → Fulfill → Analyze → Repeat
The result is a technology platform designed not around one feature, but around how the modern hobby actually operates.
One Technology Stack for the Entire Hobby
HobbyScan brings together tools that traditionally live across dozens of disconnected platforms.
AI Identification & Intelligence
At the foundation is HobbyScan’s AI-powered identification technology.
- AI card identification from camera and photos
- Sports card, TCG, slab, and sealed-product identification
- UPC and barcode scanning
- Parallel and variant recognition
- Image matching and duplicate detection
- Automatic card and product metadata
- Collection and catalog organization
- Rapid-fire and batch scanning workflows
A collector can scan an item and immediately turn that physical asset into a structured digital record that can move through the rest of the HobbyScan ecosystem.
Inventory Management
For dealers and shops, HobbyScan becomes a central inventory system.
Products can be scanned directly into inventory, enriched with market data, and connected to selling channels.
Inventory capabilities include:
- Scan directly into inventory
- Bulk imports
- Photo and image ingestion
- Quantity and cost-basis tracking
- Dynamic market values
- Locations, bins, and labels
- QR labels
- Singles, wax, and slabs
- Advanced inventory search and filtering
- Store, online, and live inventory from one system
- Multi-location and multi-store support
The same asset can move through the entire business without being re-entered into multiple systems.
Marketplace & Omnichannel Selling
HobbyScan connects inventory directly to the places businesses sell.
- One-tap listing
- eBay integration
- Shopify integration
- Marketplace pricing
- Listing creation from scanned data
- Inventory synchronization
- Automatic delisting after sale
- Cross-channel inventory control
- Affiliate marketplace and link-outs
- Sell or list directly after identification
A product doesn’t simply enter a database.
It can go from scan → valuation → listing → sale.
Market Data & Valuation
Identification is only the beginning.
HobbyScan connects scanned products to market intelligence to help users understand what their assets are actually worth.
- Current market-value estimates
- Multiple-source price aggregation
- Average and comparable-sale calculations
- Recent sold comps
- Raw vs. graded valuations
- Grade-specific values
- Direct links to pricing sources
- Profitability analysis
- Raw value vs. grading cost vs. expected graded value
This turns a simple scan into a decision-making tool.
AI Pre-Grading
HobbyScan also brings intelligence into the grading decision.
Users can move from identification and valuation directly into an AI-assisted pre-grading workflow.
- Surface and condition analysis
- Centering analysis
- Corner and edge feedback
- Estimated grade ranges
- Capture-quality and lighting guidance
- Identification of cards potentially worth grading
- Scan → pre-grade → submission decision workflow
Instead of simply asking “What card is this?”, HobbyScan helps answer:
“What should I do with it?”
Grading & Submission Workflows
HobbyScan extends beyond the individual collector and into the grading ecosystem.
The platform supports:
- Bulk submission lots
- Submission-center and dealer workflows
- Customer checkout and payment
- Submission tracking
- CGC workflow integration
- Dealer and public pricing logic
- Grading-return inventory reconciliation
This creates a connected path from discovery to grading to inventory without requiring businesses to manually move data between systems.
Hobby-Shop POS
For physical hobby shops, HobbyScan extends into the store itself.
The platform provides a connected point-of-sale experience for:
- Singles
- Slabs
- Wax
- Supplies
- Customer profiles
- Inventory-connected checkout
- Discounts and promotions
- Transaction history
- Reporting
- Store credit
- Buy / sell / trade workflows
- Market-value-assisted purchasing
Inventory, customer activity, transactions, and market data can all operate from the same underlying technology.
Payments Built Into the Experience
HobbyScan also removes friction from transactions.
The platform supports:
- Stripe payments
- Apple Pay
- Tap to Pay on iPhone
- Phone and card checkout
- Online payments
- In-store payments
- Supported workflows without requiring specialized terminal hardware
That means the same technology stack can support transactions online, in-store, at events, and during live commerce.
Live Commerce & Breaks
The hobby isn’t just about static listings.
HobbyScan brings inventory directly into the increasingly important world of live commerce.
Live selling capabilities include:
- Native live streaming
- Live selling
- Inventory attached directly to streams
- Break management
- PYT and random-team formats
- Fill meters and queues
- Break scheduling
- Customer checkout
- Shipping management
- Live inventory deduction
- Stream discovery and feeds
- Picture-in-picture card scanning
- Real-time card identification and value overlays
For breakers, the platform connects the stream, the product, the customer, the transaction, and the inventory.
Break Management
HobbyScan also provides the infrastructure behind the break itself.
- Create breaks from inventory
- Team and slot management
- Randomization
- Fill tracking
- “Breaking Soon,” “Hot,” and “Filling” discovery
- Customer purchases
- Breaker controls
- Shipping and order fulfillment
- Auditable randomization workflows
What traditionally requires several disconnected tools can operate as part of one platform.
Customer Collections & Vault
HobbyScan isn’t only built for businesses.
Collectors can maintain their own digital collection and make decisions around the physical assets they own.
- Personal inventory and collection
- Scan history
- Market values
- Graded and raw tracking
- Purchase history
- Sell, list, or grade decisions from the same asset record
Every interaction builds on the same underlying asset data.
Events & Hobby Shows
HobbyScan also extends beyond the store and into the physical events that power the hobby.
Through HobbyShow, the platform supports the technology behind hobby shows and venues.
Event capabilities include:
- Show creation
- Venue management
- Event pages
- Ticketing
- Attendee registration
- Vendor registration
- Table reservations
- Vendor and table management
- Floor-plan organization
- Payments
- Check-in
- Exhibitor management
- Event promotions and discounts
HobbyScan can also connect directly into vendor operations at events, giving merchants access to prepared inventory, POS, Tap to Pay, and the broader HobbyScan ecosystem while they’re on the show floor.
The Technology Behind the Ecosystem
Building a platform like HobbyScan isn’t simply about building an app.
It requires connecting AI, mobile applications, marketplaces, payments, inventory systems, commerce infrastructure, real-time data, streaming, POS, and event technology into one cohesive experience.
Doejo has helped build that underlying technology across:
iOS · Android · PWA · AI inference · eBay · Shopify · Stripe · Firebase · Payments · Inventory · POS · Live Commerce · Events · Grading Workflows
The architecture is designed to support new products, integrations, workflows, and business models as HobbyScan continues to expand.
Built to Scale With the Hobby
What makes HobbyScan particularly interesting is the network effect between its different systems.
A card can begin as a scan.
That scan can become a valuation.
The valuation can inform a grading decision.
The graded card becomes inventory.
That inventory can become an eBay or Shopify listing.
The same inventory can appear in a store, live stream, or hobby show.
The resulting transaction feeds back into customer data, market intelligence, inventory, and business analytics.
One asset. One technology stack. An entire business lifecycle.
Built by Doejo
HobbyScan represents the kind of complex technology ecosystem Doejo specializes in building.
We helped transform an initial AI card-scanning concept into a broader platform connecting collectors, dealers, retailers, marketplaces, grading, payments, live commerce, and events.
It’s not simply a card scanner.
It’s infrastructure for an entire industry.
