Password manager with external fingerprint reader keyboard for T500

[zilla]

If I get the Lenovo Fingerprint Reader Keyboard for when I have my T500 in the minidock with an external monitor, will the password manager be able to switch seamlessly between the two fingerprint readers?

One reason for asking is that I see the T500 fingerprint reader has a different manufacturer and thus different software drivers than earlier Thinkpads and so will probably also be different from the reader in the external keyboard, which shipped in 2005.

I am trying to reduce the hazzle of password manager prompting me when docked and not having access to the thinkpad fingerprint reader, so what I don't need is new password manager problems when switching to an external fingerprint reader.
