Understanding the security framework behind RSA SecurID

An article published in EET which the author shares his view on weaknesses of RSA SecurID [read].

In this article, the author claims that there is vulnerability that can be used by attackers to gain access on system using RSA SecurID. I've yet to verified this but still I don't think that RSA SecurID or any of token-based security is secure enough. It shall be implemented with few security mechanism on top of that to tighten the security. Or else, someone might found a way to exploit it. :)
