Entry Automation

General Implementation Notes

The system needs to be powered, and preferably include a UPS
Overriding key access is nice for graceful failure
- Of course, this just underlines the fact that this is an access registry system more than anything
Probably need a normal handle in the door with an electric door strike for the cheapest implementation.
If the implementation simply replaces the metal key with a token, it will have the same problems. Unless two- or three-factor authentication is used and/or the physical security of the lock and door are improved, it's about as secure as it was.

Hands-off access
Hands-off tracking of access
- As long as user has their RFID tag on them, their presence within a certain proximity around the reader will be recorded.

Need a reader with good range. Can be found for under $100
To build a system that can perform coming/going detection, would need two readers. or 1 + N readers, where N is the number of approachable directions
Need a writer. Under $100
- Some writers are substantially more expensive. Q: Why the price difference?
Need a server

Hands-on access
1 wire interface may be fakable with any interface that has the same signal levels (very cheap and easy buttonforging)

- It doesn't matter. Old keys are still eliminated from the system. And the threat of theft through kicking the door in is much higher than copying a valid key. --Korc 20:51, 8 May 2008 (CDT)
User may forget to log their entry to the area.
- If door is open, no incentive to use key
- Group of people walk in at once
- Someone knocks and has the door opened for them
- All these Cons are valid for any system --Korc 19:26, 8 May 2008 (CDT)
