GuardDog Models
Two types of GuardDogs are currently available:
• The iButton GuardDog requires a Dallas Semiconductor iButton be used for enrollment and
authentication. The iButton is extremely rugged and sturdy because the computer chip is pro-
tected by a metal enclosure.
• The contactless GuardDog requires a contactless smart card that operates on the Philips
MIFARE® communication standard (ISO 14443A). While not as rugged as the iButton, the
contactless smart card offers the convenience of proximity cards without compromising
security.
