## Abstract

Systems and techniques for providing a near field communication (NFC) based key control service and automated notification system are provided for automatically reporting unauthorized or restricted uses of an NFC-enabled physical key to the primary user or owner of the key via a communication network. An NFC reader is configured to communicate with a server of the NFC based key control service via a network in order to report attempted violations of one or more use restrictions defined for the key, as detected by the NFC reader when the NFC tag embedded within the key is located near a third-party device associated with a restricted use of the key.

## Claims

### Claim 1

A computer system, comprising:
a communication interface configured to enable communication through a network;
a processor coupled to the interface;
a memory accessible to the processor; and
programming stored in the memory, wherein execution of the programming by the processor configures the computer system to perform functions, including functions to:
receive, via the network and the communication interface from a first communication device, a message indicating an attempted use of a physical key equipped with a second communication device that is configured to communicate with the first communication device when the second communication device is within a predetermined proximity of the first communication device, the message including information identifying the physical key and information related to the attempted use detected by the first device;
determine whether or not the attempted use of the physical key has been restricted by a primary user or owner of the physical key, based on the information included within the received message; and
when the attempted use is determined to be a restricted use of the physical key, transmitting, to a computing device of the primary user via the network, a message notifying the primary user or owner of the restricted use.

### Claim 2 (depends on 1)

The computer system of claim 1, wherein the processor further configures the computer system to perform functions to:
send, to the first communication device via the network, a message instructing the first communication device to prevent the restricted use of the physical key, when the attempted use is determined to be a restricted use of the physical key.

### Claim 3 (depends on 1)

The computer system of claim 1, wherein the notification message transmitted to the primary user includes a time when the restricted use of the physical key was detected by the first communication device and a location of the restricted use of the physical key, as detected by the first communication device.

### Claim 4 (depends on 1)

The computer system of claim 1, wherein the first communication device is a near field communication (NFC) reader and the second communication device is an NFC target embedded within the physical key.

### Claim 5 (depends on 4)

The computer system of claim 4, wherein the information identifying the NFC target includes a unique identifier associated with the physical key, and stored within the NFC target.

### Claim 6 (depends on 4)

The computer system of claim 4, wherein the network is a mobile communication network operated by a wireless carrier and the unique identifier associated with the physical key is stored in association with a service account of the user for communication services provided to the user by the wireless carrier via the mobile communication network.

### Claim 7 (depends on 4)

The computer system of claim 4, wherein the physical key operates a mechanical lock for accessing an item of physical property owned by the primary user or owner, and the restricted use is an access restriction defined by the primary user or owner for the physical property.

### Claim 8 (depends on 4)

The computer system of claim 4, wherein the NFC reader is coupled to a key duplication device, and the restricted use is a restriction on duplication of the physical key.

### Claim 9 (depends on 8)

The computer system of claim 8, wherein parameters limiting the restriction on duplication of the physical key are defined by the primary user or owner of the physical key.

### Claim 10 (depends on 9)

The computer system of claim 9, wherein the parameters limiting the restriction on duplication of the physical key include a time parameter, a location parameter and a quantity parameter.

### Claim 11

A computer-implemented method, comprising:
receiving, at a server via a network from a first communication device, a message indicating an attempted use of a physical key equipped with a second communication device that is configured to communicate with the first communication device when the second communication device is within a predetermined proximity of the first communication device, the message including information identifying the physical key and information related to the attempted use detected by the first device;
determining whether or not the attempted use of the physical key has been restricted by a primary user or owner of the physical key, based on the information included within the received message; and
when the attempted use is determined to be a restricted use of the physical key, transmitting, to a computing device of the primary user or owner via the network, a message notifying the primary user of the restricted use.

### Claim 12 (depends on 11)

The method of claim 11, further comprising:
sending, to the first communication device via the network, a message instructing the first communication device to prevent the restricted use of the physical key, when the attempted use is determined to be a restricted use of the physical key.

### Claim 13 (depends on 11)

The method of claim 11, wherein the notification message transmitted to the primary user includes a time when the restricted use of the physical key was detected by the first communication device and a location of the restricted use of the physical key, as detected by the first communication device.

### Claim 14 (depends on 11)

The method of claim 11, wherein the first communication device is a near field communication (NFC) reader and the second communication device is an NFC target embedded within the physical key.

### Claim 15 (depends on 14)

The method of claim 14, wherein the information identifying the NFC target includes a unique identifier associated with the physical key, and stored within the NFC target.

### Claim 16 (depends on 14)

The method of claim 14, wherein the network is a mobile communication network operated by a wireless carrier and the unique identifier associated with the physical key is stored in association with a service account of the user for communication services provided to the user by the wireless carrier via the mobile communication network.

### Claim 17 (depends on 14)

The method of claim 14, wherein the physical key operates a mechanical lock for accessing an item of physical property owned by the primary user or owner, and the restricted use is an access restriction defined by the primary user or owner for the physical property.

### Claim 18 (depends on 14)

The method of claim 14, wherein the NFC reader is coupled to a key duplication device, and the restricted use is a restriction on duplication of the physical key.

### Claim 19 (depends on 18)

The method of claim 18, wherein parameters limiting the restriction on duplication of the physical key are defined by the primary user or owner of the physical key.

### Claim 20 (depends on 19)

The method of claim 19, wherein the parameters limiting the restriction on duplication of the physical key include a time parameter, a location parameter and a quantity parameter.
