The system provides a method and apparatus for providing controlled access to premises. The system in one embodiment uses a reader/scanner associated with a controlled entrance that can receive credentials manually or via scanning or some other form of electronic communication. In one embodiment, the system uses NFC (Near Field Communication) from a mobile device to determine if access should be granted. The system contemplates a number of different tiers of users whose right of access to a location depends on the tier in which the user resides. For one time visitors, the system contemplates transmitting an access credential that can be used by a specific user for a limited time period. In some cases, the access credential is tied to a particular device.
