The site is only an example. You would actually order your own unique card to carry with you. No one would be able to guess your password since your spacebar

  That doesn't change the GP's point. One compromise means that password and spacebar code is compromised for all passwords. Other comments have already addressed how wimpy a substitution cipher is. Add to that that you can't reasonably cycle keys here, and you have yourself one pretty terrible password system.

  This is wishful thinking, factor in the actual organization doing global surveillance and spying, say NSA who is known to intercept hardware to flash firmware with backdoors and suddenly the need to guess is no more, your card can be legally copied at any point between production or transportation to you.

    Oh my god, if you really worry about NSA hacking your accounts, then probably this card is not for you. And they probably don't need to guess your passwords, they can just get in with a court order. This is for people who are still using passwords like "password12345" because ".;l[ppop[o#@!" is too hard to remember.
