The website and app should both support UPC barcode scanning.  You can submit a photo to the website using a your computer webcam (or a UPC scanning device).  On the app, you can search by UPC code too.  Click the "Scan Barcode or Card" button on the iOS app home page.  Then click the "UPC" symbol (the symbol on the right).  The other symbol is for searching for cards by photo instead UPC.

Let me know if this works for you.  If you have any problems let me know too.

What do you mean by groups?  Can you give me an example item and what group it is in?

Closing as a duplicate.

We have Marvel cards here:

https://www.pricecharting.com/category/marvel-cards

We do not have immediate plans for that.  Sorry.  I've made notes about this discussion though because I can see that being useful for some users.  We have to prioritize that with other feature requests and site code so I don't have an ETA.

Thanks for this feedback.  We have a collection import tool that could work for something like that.

You would need to use some Excel skills to quickly generate the issue names though.  

To get more info on your idea.  You would be able to click a checkbox next to each issue to add, and then choose the folder you want to add all of those to in your collection.  Is that about what you expected for the user interface on something like this?

Thanks for this feedback.  I can see how a default folder would be useful.  

Can you give me an example item or two on the site with this issue?  I want to look into this more.  Thanks

You can import collections now:

https://www.pricecharting.com/collection-text-importer

The items are automatically grouped into pre-built "folders" for the category (Pokemon, Magic, etc) and the set.  If you filter your collection by category first (Magic Cards), then you will see the ability to filter the list further by Set.  

The folders would only be needed if you want custom sorting like "Stuff I Lent My Brother", "In Binder 5", etc.  The set is a pre-built organizational method for every collection.

Thanks for this feedback.  We might have room for that on larger screens, but I'll need to think about it more and the possibility of it from a tech perspective too.  

If you click the "In Collection" icon, that will take you directly to that item in your collection so you can see was is included.  It is an extra click, but it will give you the answer right now.
