## Abstract

Systems and methods are provided to allow a smart phone or any terminal to activate a door lock using a web site or server computer system. An access control system is provided that includes a server and an access device. The access device includes a processor and a communication module. The process has control of a door lock and is able to receive a reservation certificate presented by a portable terminal through the communication module. The processor activates the door lock when a current reservation certificate has been presented.

## Claims

### Claim 1

An access control system comprising:
a) an access device comprising a communication module connected to a processor having control of a door lock;
b) a secure reservation interface to receive a reservation request from a first device for a reservation at a given destination, the reservation interface comprising one or more screens for receiving a selection of a location at the destination and an interval of the reservation;
c) a reservation server, in communication with the reservation interface and a network, to:
receive the reservation request for the destination, the reservation request including a selected location at the destination and an interval of the reservation;
issue a reservation certificate describing the interval of the reservation based on the reservation request and the selected location; and
transmit, via the network, from the reservation server to a second device distinct from the first device, the reservation certificate and a communication setting corresponding to the access device;
d) an application installed on the second device to receive the reservation certificate and the communication setting corresponding to the access device, wherein the application wirelessly transmits the reservation certificate to the access device using the communication setting upon receipt of a command to activate the door lock; and
e) wherein the access device receives the reservation certificate from the application based on use by the application of the communication setting, and the processor activates the door lock based on at least the receipt of the reservation certificate.

### Claim 2 (depends on 1)

The system of claim 1 wherein the access device comprises a unique identifier, and wherein at least the reservation certificate or the communication setting contains the unique identifier.

### Claim 3 (depends on 2)

The system of claim 2 wherein at least a portion of the reservation certificate is encrypted.

### Claim 4 (depends on 1)

The system of claim 1 wherein the reservation server receives a request for one or more amenities at the destination.

### Claim 5 (depends on 1)

The system of claim 1 wherein the access device generates a record indicating that the processor activated the door lock.

### Claim 6 (depends on 1)

The system of claim 1 wherein the reservation certificate automatically expires at the end of the interval of the reservation.

### Claim 7 (depends on 1)

The system of claim 1 wherein the second device comprises a smartphone.

### Claim 8 (depends on 1)

The system of claim 1 wherein the access device comprises a Bluetooth transceiver.

### Claim 9 (depends on 3)

The system of claim 3 wherein the access device decrypts the encrypted portion of the reservation certificate.

### Claim 10 (depends on 3)

The system of claim 3 wherein the application installed on the second device decrypts the encrypted portion of the reservation certificate.

### Claim 11 (depends on 1)

The system of claim 1 wherein the reservation interface comprises one or more screens for selecting one or more amenities at the destination.

### Claim 12 (depends on 1)

The system of claim 1 wherein the reservation detail interface comprises one or more screens for selecting at least a start time and a stop time, or a duration for the reservation.

### Claim 13

An access control system comprising:
a) an access device comprising a communication module connected to a processor having control of a door lock restricting access to a room at a given location, the access device comprising at least a Bluetooth transceiver;
b) a reservation interface comprising one or more reservation screens associated with the location, the one or more reservation screens for selecting at least a room and an interval for a reservation at the location;
c) a reservation server, in communication with the reservation interface and a network, to:
receive a reservation request comprising at least a selected room and an interval for a reservation;
issue a reservation certificate, the reservation certificate describing an interval of the reservation for the room based on the reservation request; and
transmit, via the network, from the reservation server to an application installed on a smartphone, the reservation certificate and a communication setting corresponding to the access device;
d) a smartphone application installed on the smartphone to receive the reservation certificate and the communication setting corresponding to the access device, wherein the smartphone application wirelessly transmits, via Bluetooth, the reservation certificate to the access device using the communication setting upon receipt of a command to activate the door lock; and
e) wherein the access device receives the reservation certificate from the smartphone application based on use by the smartphone application of the communication setting, and the processor activates the door lock based on at least the receipt of the reservation certificate.

### Claim 14 (depends on 13)

The system of claim 13 wherein the reservation interface comprises one or more reservation screens associated with the location, the one or more screens for selecting one or more amenities at the location.
