Card Codex is out of testing and available to everyone.
Point your camera at a card and it's identified in a second or two, with what
it's currently worth. Scan cards still in their sleeves, or straight off a
binder page — no need to take anything out.
Cards are recognised on your device, so scanning works with no signal and
needs no account.
Build a list as you scan, then send it to your collection on cardcodex.com.
Thanks to everyone who tested it.
