You don't have to scan them, just add them to your organize by card number/name. All real time pricing, too. Shows your if a card is going up or down in value, I used to buy the Beckett magazine when I was a kid haha.
I have Becketts stashed away. My brother used to do card shows and picked up a few good cards for me. A Lemieux rookie card that was $400 back in the day. Not even sure what it's worth now. Jersey cards...a ton of memorabilia in mint condition all stashed away. Such a geek.
