How to use the Collection tracker

Photo to portfolio in four steps

Tap through the walkthrough to see exactly what happens after you add a card — on your phone or on your computer.

1 · Add a card photo

On your phone, tap Add card and take a picture of the front of the card. On a computer, drop in a photo you already have. Raw cards and graded slabs both work.
