The access device includes a processor having control of a door lock, and a communication module connected to the processor. The processor is able to receive a reservation certificate presented by a portable terminal through the communication module. The processor activates the door lock when the current reservation certificate has been presented and disables an alarm system when the current reservation certificate has been presented. ## Claims ### Claim 1 An access device for use in access control systems, the access device comprising: a communication module connected to a processor having control of a door lock and an alarm; wherein the processor receives a reservation certificate from a smartphone, the reservation certificate describing an interval of a reservation, and the processor further activates the door lock based on the reservation certificate and the processor disables the alarm based on the reservation certificate. ### Claim 2 (depends on 1) The access device of claim 1 wherein the processor has access to the current time and the processor activates the door lock during the interval. ### Claim 3 (depends on 2) The access device of claim 2 wherein the interval is specified by a start time and one of an end time and a duration. ### Claim 4 (depends on 1) The access device of claim 1 further comprising: a memory to which the processor has access, the memory containing a public key for a server authorized to issue the reservation certificate; wherein at least a portion of the reservation certificate is encrypted by the server using a private key and the processor verifies that the reservation certificate is genuine by decrypting the portion with the public key. ### Claim 5 (depends on 1) The access device of claim 1 further comprising: a memory to which the processor has access, the memory containing a symmetric key; wherein at least a portion of the reservation certificate is encrypted by a server using the symmetric key and the processor verifies that the reservation certificate is genuine by decrypting the portion with the symmetric key. ### Claim 6 (depends on 1) The access device of claim 1 wherein the processor verifies that the reservation certificate is genuine. ### Claim 7 (depends on 1) The access device of claim 1 further comprising: an identification to which the processor has access, the identification corresponding to one of the access device and the door lock, wherein the processor determines that the reservation certificate comprises data representative of the identification. ### Claim 8 (depends on 1) The access device of claim 1 further comprising: a memory to which the processor has access, the memory containing a private key of the access device; wherein at least a portion of the reservation certificate is encrypted by a server using a corresponding public key for the access device and the processor decrypts the portion with the private key. ### Claim 9 An access control system comprising: an access device comprising a communication module connected to a processor having control of a door lock and an alarm; a server to provide a communication setting to a smartphone, the communication setting corresponding to the access device; the server to further provide a reservation certificate to the smartphone, the reservation certificate describing an interval of a reservation; wherein the processor receives the reservation certificate from the smartphone, based on use by the smartphone of the communications setting and the processor further activates the door lock based on the reservation certificate and disables the alarm based on the reservation certificate. ### Claim 10 (depends on 9) The access control system of claim 9 wherein the communication setting is specific to the access device. ### Claim 11 (depends on 10) The access control system of claim 10 wherein the smartphone notifies the user of proximity to the access device. ### Claim 12 (depends on 9) The access control system of claim 9 wherein the communication module does not advertise that the communication module is present. ### Claim 13 (depends on 9) The access control system of claim 9 wherein the smartphone uses Bluetooth.TM. to communicate with the access device and the communication setting comprises a Bluetooth ID. ### Claim 14 (depends on 9) The access control system of claim 9 wherein the smartphone uses Wi-Fi to communicate with the access device and the communication setting comprises a network SSID. ### Claim 15 (depends on 9) The access control system of claim 9 wherein the reservation certificate comprises the communication setting. ### Claim 16 An access control system comprising: an access device comprising a communication module connected to a processor having control of a door lock and an alarm; a server to provide a communication setting to a smartphone, the communication setting corresponding to the access device; the server to further provide, via a first communication protocol, a reservation certificate to the smartphone, the reservation certificate for an interval of a reservation; wherein the processor receives the reservation certificate from the smartphone via a second communication protocol that is different from the first communication protocol, based on use by the smartphone of the communication setting and the processor further activates the door lock based on the reservation certificate and disables the alarm based on the reservation certificate. ### Claim 17 (depends on 16) The access control system of claim 16 wherein the first communication protocol comprises a cellular protocol. ### Claim 18 (depends on 16) The access control system of claim 16 wherein the first communication protocol comprises a wireless LAN protocol. ### Claim 19 (depends on 16) The access control system of claim 16 wherein the smartphone automatically connects to the access device via the second communication protocol as the smartphone approaches the access device. ### Claim 20 (depends on 16) The access control system of claim 16 wherein the server provides, via the first communication protocol, the reservation certificate to an application installed on the smartphone.
