Scan For Cards

Trading card collectors know the grind: sellers post cards that sell in minutes, and by the time you check, they're already gone. Manually tracking dozens of sellers every day isn't a hobby — it's a second job. ScanForCards automates your watchlist. The extension runs quietly in the background, monitoring the seller accounts you follow. When it spots a card that matches something on your watchlist — a specific player, set, grade, or cert number — it fires a Telegram alert instantly, so you can act before the card disappears. **How it works:** Create an account at scanforcards.com, install the extension, and click "Sign in with Scan For Cards" (works for Google and email accounts). Build your watchlist in the dashboard: players, sets, years, grades, grading companies, and price ceilings. Choose how often to scan (every 4, 8, 12, or 24 hours) or click Scan Now any time. Your scan schedule is saved to your account, so it follows you between the dashboard and the extension.
