Doorbot

We need a door control system. Preferably one that works with the RFID fobs handed out by UR for the main door at ACTA, since otherwise we'd need two parallel fob administrations and have added cost for our own fobs.

In addition we have outlined the need for two-factor auth, so we want to add a keypad to this, where you type your PIN.

UR HID RFID Fobs

They don't seem to work with a standard reader. I believe at ACTA we tried reading a UR fob with a PC rfid reader, which did not work. Later, ultratux tried to add a borrowed UR fob to a RFID system he has http://www.conrad.nl/ce/nl/product/751242/ which also did not work.

Justa suggests studying the HID ProxkeyIII dox to find out why it might be incompatible. There may be general crypto stopping non-HID devices talking to HID devices. In that case we could solve it by acquiring a HID ProxkeyIII reader off ebay. However, there may even be a crypto key inside the UR reader that was created unique to UR, in which case all our attempts will fail.

Door access system

• Embedded hardware so it won't be bluescreening or some such. This is critical infra, people.
• Queries internal LDAP server for auth

Which requirement collides with Justa's voiced requirement that it is linked to the UR fob membership administration. So I think we should forget about the LDAP. Please comment.

• Discuss whether the lock must be normally-open or normally-closed. In the latter case the space stays secure at the time of a power failure. In the normally-open case either the space unlocks, or we need to invest in a no-break / UPS...
