Systems and methods facilitate entry into an access-controlled location using a mobile communication device. The method comprises receiving at the mobile communication device via a communication network an entry code that facilitates access to the access-controlled location, storing the entry code in a memory associated with the mobile communication device, and, in response to determining that the mobile communication device is within the predetermined distance of the access-controlled location, transmitting the entry code from the mobile communication device to an entry-control computer system, which determines whether the entry code is valid. The method may further comprise receiving at the mobile communication device an indication that the entry code is valid, and, in order to gain entry into the access-controlled location at an entrance to the access-controlled location, providing to the entry-control computer system via the mobile communication device the indication that the entry code is valid.
