Entry Automation

RFID

Pros

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

Cons

• Keys easily stolen and duplicated with anonyminity

iButton

Pros

• Rotating keys are available
• Someone must have physical access to the fob to capture the non-rotating key
  • Could capture key with access to the database, but RFID has this same weakness

Cons

• Hands-on access
• 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
