## Abstract

A method for tracking pieces of baggage comprises the steps of providing one or more first devices, each of the first devices being attached to the pieces of baggage and each of the first devices comprising a first transceiver; transmitting, by each of the first transceivers, wireless data, the wireless data comprising a device identifier for the respective first device; providing a second device, the second device comprising a second transceiver and a user interface; receiving, by the second transceiver, the wireless data from one or more of the first transceivers; displaying on the user interface the device identifiers corresponding to the respective first devices from which the wireless data was received; selecting one or more of the device identifiers, the selected one or more of the device identifiers corresponding to the first devices that are selected for tracking; and generating, by the second device, an alarm if one of the first devices that are selected for tracking moves beyond a particular distance from the second device, wherein the particular distance may be determined using a signal strength of the wireless data received by the second transceiver.

## Claims

### Claim 1

A method for tracking pieces of baggage, the method comprising the steps of:
providing one or more first devices, each of the first devices being attached to the pieces of baggage and each of the first devices comprising a first transceiver;
transmitting, by each of the first transceivers, wireless data, the wireless data comprising a device identifier for the respective first device;
providing a second device, the second device comprising a second transceiver and a user interface;
receiving, by the second transceiver, the wireless data from one or more of the first transceivers;
displaying on the user interface the device identifiers corresponding to the respective first devices from which the wireless data was received;
selecting one or more of the device identifiers, the selected one or more of the device identifiers corresponding to the first devices that are selected for tracking; and
generating, by the second device, an alarm if one of the first devices that are selected for tracking moves beyond a particular distance from the second device, wherein the particular distance may be determined using a signal strength of the wireless data received by the second transceiver.

### Claim 2 (depends on 1)

The method of claim 1, wherein the first device further comprises a locking mechanism for securing contents of the piece of baggage.

### Claim 3 (depends on 1)

The method of claim 1, wherein the first device further comprises a light,

### Claim 4 (depends on 1)

The method of claim 1, further comprising the steps of:
transmitting, by the second device, the alarm to the one of the first devices; and
receiving, by the one of the first devices, the alarm.

### Claim 5 (depends on 3)

The method of claim 3, further comprising the step of:
upon receiving by the one of the first devices the alarm, the one of the first devices illuminating a light located on an exterior of the one of the first devices.

### Claim 6

A system for tracking pieces of baggage, the system comprising:
one or more locks, wherein each of the one or more locks being removably attached to the pieces of baggage, and wherein each of the locks comprises:
a first transceiver; and
a locking mechanism configured for securing contents of the pieces of baggage; and
a communication device comprising:
a user interface for displaying information; and
a second transceiver configured to communicate wirelessly with one or more of the first transceivers;
wherein each of the first transceivers is configured to transmit data, the data comprising a lock identifier for the respective lock;
wherein the second transceiver is configured to receive data from one or more of the first transceivers;
wherein the communication device is configured to display on the user interface the lock identifiers corresponding to the respective locks from which data was received;
wherein the user interface is configured to accept input regarding a selection of one or more of the lock identifiers displayed on the suer interface, the selection corresponding to the respective locks selected for tracking; and
wherein the communication device is further configured to generate an alarm if one of the locks selected for tracking moves beyond a particular distance, the particular distance determined using a signal strength of the data received by the second transceiver.

### Claim 7 (depends on 6)

The system of claim 6, wherein the communication device is further configured to transmit the alarm to the lock that is moved beyond the particular distance.

### Claim 8 (depends on 7)

The system of claim 7, wherein each of the locks further comprises a light located on an exterior of the lock.

### Claim 9 (depends on 8)

The system of claim 8, wherein each of the locks is further configured to, upon receipt of the alarm, cause illumination of the light.
