<p>Hi Tom. At NDNF, we are approaching this model, slowly. Our
campus recently switched to RFID+magstripe smart cards to replace
magstripe-only student/staff/faculty ID cards. I was able to
locate a generic (Pacific Rim origin) RFID reader for about $10;
it's USB and it reliably reads the card ID from these new smart
cards. My goal is to add these readers to key equipment, as well
as to our Coral computers, in the cleanroom. For equipment, the
reader can be connected to, say, a networked Raspberry Pi, one per
tool, which can inform the Coral server that someone needs that
tool to be enabled. The coral server can then take care of the
bookkeeping, and also tell the hardware interlock to enable.</p>
<p>The good thing: this approach builds on our current
infrastructure, at a manageable one-time cost. The bad thing: it's
not quite what you are looking for, as it's not a comprehensive
3rd-party turnkey solution.<br>
</p>
<p>The other big drawback: I expect to see the same sort of behavior
that we get now with Coral + hardware interlocks: folks <b>enable</b>
and then <b>forget to disable</b>. (I'm not even sure a big
bright flashing "ENABLED!!!" display on the tool would help.) This
of course messes up the monthly cost recovery ("I used it for HOW
MANY HOURS?????"), and also allows (or "fails to prevent") other
users sneaking in and using the tool while it's enabled. I've
thought about implementing auto-timeouts (disable on timeout), but
this quickly becomes very tool-specific and can potentially cause
process disruption ("Hey, how come the spinner just stopped?!?").
<br>
</p>
<p>Anyone have any good ideas regarding this issue?</p>
