4.3 AI Card Recognition — Scan Settings
When uploading images for AI processing, configure the following:
Format
Single Items — each photo contains one card
Flatbed Scanner — multiple cards per image (AI detects and crops each card)
Content
Front and Back (Recommended)
Front Only or Back Only — if that's what you scanned
Authentication
Mixed — upload contains both graded and raw cards
All Graded — all items are graded slabs
All Ungraded (Raw) — all items are raw cards
"Prefer grading company images" checkbox — when enabled, uses official PSA/CGC images instead of your uploaded photos
Important for Flatbed Scanning: If a card is top-left on the front scan, it must also be top-left on the back scan. Do NOT move or rotate cards between scans. Keep the scanner lid OPEN (dark background helps AI detect card edges). Leave space between cards. Scan at 200 DPI or higher.
4.4 Mobile Scanning (scan.withmascot.com)
Open your phone browser and go to scan.withmascot.com.
Sign in with your Mascot email and password.
Choose Single Item mode (recommended) or Multiple Items (bulk).
Single Item: Take front photo > back photo > Continue > AI processes > Review > Save to Inventory.
Bulk: Photograph several cards laid out, take front and back group photos, AI separates each card.
Review and fix any AI mistakes (player, set, grade). Add cost, tags, or notes on mobile.
Works great at card shows for instant inventory scanning. Also works with barcode scanning for existing inventory.
4.5 Non-Card Inventory (Sealed Wax, Coins, Memorabilia, etc.)
Go to Add Inventory > Create Items Manually.
In the Quick Start popup, select Other (not Graded Card or Raw Card).
Select the appropriate Product Category:
Sports Cards, Sealed Wax / Boxes, Coins, Memorabilia, Autographs, TCG, Other Collectibles
Fill in Item Specifics: Product Name, Manufacturer, Year, Set/Series, Card Number (if applicable), Player/Athlete.
Upload images (up to 8), add grading/autograph details, purchase info, and pricing.
Click SAVE TO COLLECTION.
Import eBay Purchases
Automatically syncs new eBay purchases (in any supported category) to your Mascot inventory. Mascot saves the associated cost and adds the item directly to your collection — no manual entry needed.
Not the same as "Import eBay Listings." That feature pulls in items you're currently selling on eBay. This feature pulls in items you buy on eBay (e.g., restocking inventory from other sellers).
How to Set It Up
From the Inventory Dashboard, click Add Inventory.
Under Other Sync Tools, click Import eBay Purchases.
In the eBay Purchase Imports modal, leave (or check) Track eBay Purchases Automatically.
Click Save.
Once saved, any future eBay purchases in supported categories will automatically sync to your Mascot collection, including cost.
Where to Find Imported Items
Go to your Inventory table.
Click Columns (or the column menu) and select Imports.
In the Imports filter, choose eBay Purchases.
This filters your inventory to show only items that came in through the eBay Purchases sync — useful for reviewing new stock or auditing costs before relisting.
