Based on what I have read in this group over the years this is not a
very accurate article.

Maybe Paul C would like to comment to them?

The article indicates you can see where you have travelled with your Oyster card via the web site.
I have never found this feature, does it exist?

No. You can request a statement via the email feature in "Ask Oyster".
You have to provide your Oyster Card number, security answer and
home address. They send you the statement in the post.
