1. A method, comprising:

  • establishing a first wireless connection between a mobile device and a reader device over a long range communication protocol, wherein the reader device includes at least one transceiver for communication between the reader device and the mobile device over multiple carrier frequencies or network bands, wherein the reader device includes a lock associated with a door and the first wireless connection is established when the mobile device is a first distance from the reader device, wherein the first distance is greater than a second distance from the reader device;

    authenticating the mobile device with the reader device while the first wireless connection is established;

    triangulating, by a plurality of sensors position around the door, a position of the mobile device with respect to the door after the mobile device is authenticated and tracking an amount of time the mobile device is within a predetermined distance from the door,transmitting, with the reader device, a token from the reader device to the mobile device over the long range communication protocol via the first wireless connection while the mobile device is outside the second distance from the reader device, wherein the token is used by the mobile device to request an action from the reader device once the mobile device is within the second distance from the reader device and the token is configured to expire after a period of time;

    storing the token on the mobile device;

    after storing the token on the mobile device, wirelessly connecting the mobile device and the reader device over a short range communication protocol via a second wireless connection in response to the mobile device being within the second distance from the reader device;

    determining, by the plurality sensors, the mobile device being within the second distance from the reader device for a predetermined amount of time and determining, by the plurality of sensors, a predetermined gesture being made with the mobile device;

    transmitting, by the mobile device, the token over the short range communication protocol via the second wireless connection from the mobile device to the reader device in response to the predetermined gesture being made and to the mobile device being within the second distance from the reader device for the predetermined amount of time;

    receiving by the reader device, the token from the mobile device over the short range communication protocol via the second wireless connection;

    determining, by the reader device, the token is valid in response to the token being received from the mobile device by the reader device over the short range communication protocol via the second wireless connection within a time threshold; and

    unlocking, by the reader device, the lock in response to the token being valid, the predetermined gesture being made with the mobile device, and the mobile device being within the predetermined distance for the predetermined amount of time.
