Actually it's safer to buy online as you can store a copy of the printable pass wherever you like (on an USB stick, in the cloud, on your phone, etc). So you can print it again should you loose your first printout. You can even print it twice and keep a copy in your hotel if you like.
If you buy at the station, you will also get a piece of paper. It's not a card like a plastic credit card. They will put it in a pouch for you, but it's still one copy. If you loose it, you won't have a backup, and there's no refund.
