RFID
Pros
- Hands-off access

Cons
- Keys easily stolen with anonymity
Implementation
Materials
- 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
- Need an UPS for the server
- Need a deadbolt actuator that can be overridden standard metal key
iButton
Pros
- Rotating keys are available
- Someone must have physical access to the fob to capture the non-rotating key
Cons
- Hands-on access
- 1 wire interface may be fakable with any interface that has the same signal levels (very cheap and easy buttonforging)
- 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)
