It's a handheld cryptographic authentication calculator.
They cost ~$55 in quantity. They contain a replaceable (hot swap)
battery that keeps a DES key in memory all the time. The admin
programs the key into it -- so you don't rely on someone else
to key your authentication device.
It's fairly solid, not especially attractive, but it uses
an algorithm someone published a few years back, that's easy to
implement in software, so you can avoid host-software licensing,
portability, and availability issues.
It's one of the authentication devices the TIS firewall
toolkit supports -- we have a server-side implementation that
requires no additional software, so you can just buy 'em and key
'em and issue 'em to users.
