CollX vs Ludex vs InVelocity: Which Card Scanning App is Best for Dealers?

Every card dealer eventually hits the same wall: you're holding a stack of cards and you need to know what they're worth — fast. Three apps have become the go-to names in this space: CollX, Ludex, and InVelocity. They're built for different users with different goals, and picking the wrong one costs you either money or time.

This comparison covers what each app actually does well, where each one falls short, and which type of dealer is best served by each option.

The Short Answer

CollX is best for collectors and hobbyists who want a quick valuation of personal collections
Ludex is best for quick price checks at card shows and flea markets
InVelocity is best for card dealers who sell on eBay, run a store, or process collections at volume

If you're running a business — buying collections, listing on eBay, tracking profit — you'll outgrow CollX and Ludex quickly. If you just want to know what your binder is worth, either of those works fine.

CollX

CollX launched as a social + scanning app for trading card collectors. The pitch: scan your collection, see prices, share what you own with the community.

What CollX does well:

Fast scan-and-price for common cards
Built-in marketplace where collectors buy and sell directly
Community features (following other collectors, showcasing collections)
Works across multiple card types (sports cards, TCG, gaming)

Where CollX falls short for dealers:

Scanning accuracy degrades on variant-heavy games like Pokemon (reverse holo vs regular vs full art are not reliably distinguished)
No inventory management beyond a basic collection list
No eBay integration — you can't push listings from CollX to eBay
Pricing is reference-only; you can't manage cost basis, track profit, or set selling prices
No purchase/sale history tracking
The marketplace is CollX's own platform — not eBay or TCGPlayer where most dealers actually sell

CollX works well for personal use and casual resale. For a dealer processing 10+ collections a month, the workflow breaks down immediately. There's no concept of "cost I paid" vs "price I'm selling for," no eBay sync, and no bulk operations.

Ludex

Ludex is focused on one thing: quick price scanning at the point of purchase. It's built for the "I'm standing at a flea market or card show and need to know if this collection is worth buying" use case.

What Ludex does well:

Very fast scan-to-price (optimized for speed over depth)
Clean interface — minimal friction for quick lookups
Bulk scan mode for fast collection assessments
Works without an account for basic pricing

Where Ludex falls short for dealers:

No inventory management — scanned cards don't persist in a usable format
No eBay or TCGPlayer integration
No cost tracking, profit tracking, or financial reporting
No listing generation
Variant accuracy on Pokemon and Magic is inconsistent
Pricing pulls from TCGPlayer market price but doesn't offer the 90-day trend context you'd want for buy decisions

Ludex is a solid companion app for buying decisions. Pull it out at a card show, scan a stack, decide whether to make an offer. But once you've bought the collection and need to catalog, price, and sell it — Ludex gives you nothing.

InVelocity

InVelocity is built for the full dealer workflow: acquire → catalog → price → list → track.

What InVelocity does well:

AI photo scanning with variant detection (identifies the exact printing — reverse holo, full art, alternate art, etc.)
Live TCGPlayer market prices + Invelocity Price (real sold data from eBay, more accurate than listing-based market prices)
90-day price trend charts on every card
Full inventory management with cost basis, selling price, margin tracking
eBay integration: push listings directly from InVelocity to eBay, sync quantities and prices
Public storefront where customers can browse your inventory
Stocking recommendations based on sales velocity
Best offer management from the InVelocity dashboard

Where InVelocity falls short:

It's not designed for single-card lookups — it's overkill if you just want to know what one card is worth
No built-in buying/selling marketplace (it integrates with eBay and TCGPlayer rather than operating its own)
Steeper learning curve than CollX or Ludex for non-business use

Scanning Accuracy: The Detail That Matters

All three apps can scan a Near Mint Pikachu from Base Set. The meaningful test is whether the app distinguishes:

A regular Charizard from a holo Charizard
A reverse holo Pikachu from a regular Pikachu
A Pokemon ex full art from a regular ex
A special illustration rare from a standard illustration rare

Pokemon alone has more than 18,000 unique printings across 25+ years of sets. CollX and Ludex handle the most common cards reliably. InVelocity uses a multi-layer pipeline — AI vision to read the card, a rarity/treatment scoring pass, and CLIP visual matching for ambiguous reprints — which handles the harder cases that matter for dealer pricing.

The price difference between a regular Charizard ex and a special art rare Charizard ex from the same set can be 3-5x. An app that can't distinguish those variants is a liability when you're buying or pricing collections.

Which App for Which Dealer?

Use CollX if:

You're a collector wanting to track personal collection value
You want to sell cards directly within a collector community
You're not running eBay at any real volume

Use Ludex if:

You buy collections at card shows or estate sales and need quick on-the-spot valuations
You don't need to track inventory after purchase
You're comfortable using a separate tool for listing and selling

Use InVelocity if:

You run a card business and sell on eBay regularly
You process collections by the box and need to catalog efficiently
You track cost basis and profit margin on inventory
You want eBay listings generated from the same tool you use to scan
You want to understand your inventory's total value, velocity, and profitability

The Workflow Question

The real differentiator isn't any single feature — it's the workflow. CollX and Ludex are point-in-time tools: scan a card, see a price. They're designed for moments, not operations.

InVelocity is built around a continuous workflow:

Scan incoming cards (photo import, 200+ cards in a session)
Cards land in your inventory with market prices pre-filled
Draft listings are generated automatically
Review, adjust prices, push to eBay
Sales sync back to inventory (quantity decremented, revenue tracked)
Stocking recommendations surface what to reorder
Price change alerts surface what spiked while you were busy

No other card app closes that loop. You either do pieces of it manually across multiple tools, or you use InVelocity.

Pricing

CollX: Free tier with basic features; CollX Premium for full scanning history and marketplace tools.

Ludex: Free with a premium tier for additional features.

InVelocity: 30-day free trial, then usage-based pricing by inventory size. All features (scanning, eBay integration, storefront, analytics) are included at every tier.

For a dealer processing 10+ collections a month and running an active eBay store, InVelocity typically pays for itself in the first few hours of saved cataloging time.

Bottom Line

If you're a hobbyist: CollX or Ludex is probably enough.

If you're building a card business — buying collections, listing on eBay, tracking what's making money — InVelocity is the only tool in this comparison built for that work.

CollX was designed for collectors. Ludex was designed for buyers. InVelocity was designed for dealers.
