Abstract
An access control system is configured to detect the presence of a portable electronic device carried by a user in a first area. The access control system sends an access code to the device. In a second area, the user presents the portable electronic device to an access terminal, which reads the access code from the device. If the access code read from the device matches the access code that was sent to the device by the system, then the access control system grants access to the user.
