Lay a page of your real card binder flat, take one photo, and every pocket fills with the card and its live price. The whole binder gets a link you can show anyone. Sell cards for friends at shows? Beltstra keeps the ledger: whose card sold, for how much, what you owe them, what you paid, and one tap to list it on eBay. Scan one card free with no account. Free plan is 20 scans a month; Pro is $29/month.
