Techniques for determining movement of a device away from a preferred location

1. A method of determining movement of a peripheral device of a computer away from a preferred location comprising:

receiving a signal from a beacon of the peripheral device of the computer by the computer;

determining a measure of a characteristic of the signal by the computer;

performing a comparison of the measure of the characteristic to a predetermined threshold which is based upon a distance from the preferred location by the computer;

determining that the peripheral device has moved at least the distance from the preferred location based upon the comparison by the computer.

2. The method of claim 1 , further comprising issuing an alert.

3. The method of claim 1 , wherein issuing an alert comprises issuing an alert after a predetermined time.

4. The method of claim 2 , wherein issuing an alert comprises sending an alert message.

5. The method of claim 2 , wherein issuing an alert comprises activating an audible alarm.

6. The method of claim 2 , wherein issuing an alert comprises activating a visual alarm.

7. The method of claim 2 , wherein issuing an alert comprises activating a security camera.

8. The method of claim 1 , further comprising entering the measure of the characteristic, a date and time, and an identifier associated with the beacon in a log file.

9. The method of claim 1 , wherein the measure of the characteristic of the signal comprises signal strength.

10. The method of claim 1 , further comprising disabling a preferred function of the device.

11. The method of claim 1 , wherein the beacon comprises a Bluetooth Low Energy standard beacon.

12. The method of claim 1 , further comprising:

receiving another signal from the beacon;

determining another measure of the characteristic of the signal;

performing another comparison of the other measure of the characteristic to the predetermined threshold;

determining that the device has moved within the distance from the preferred location based upon the other comparison.

13. The method of claim 1 , wherein the beacon is in the device.

14. The method of claim 13 , performed by a computer monitoring locations of the device.

15. The method of claim 14 , further comprising:

receiving another signal from the beacon by another computer;

determining another measure of the characteristic of the signal by the other computer;

performing another comparison of the other measure of the characteristic to the predetermined threshold by the other computer;

determining that the device has moved within the distance of the other computer based upon the other comparison.

16. The method of claim 1 , wherein the beacon is adjacent the preferred location.

17. The method of claim 16 , performed by the device.

18. The method of claim 17 , further comprising:

receiving another signal from another beacon at another location;

determining another measure of the characteristic of the other signal by the device;

performing another comparison of the other measure of the characteristic to the predetermined threshold by the device;

determining that the device has moved within the distance of the other beacon based upon the other comparison.

19. The method of claim 1 , wherein the device comprises a payment peripheral.

20. A method of determining movement of a peripheral device of a computer away from a preferred location comprising:

receiving a first signal from a beacon of the peripheral device of the computer by first wireless communication circuitry coupled to the computer;

determining a first measure of the first signal by the computer;

determining a first distance from the first wireless communication circuitry based upon the first measure by the computer;

determining that the peripheral device has moved away from the preferred location and at least within a first threshold distance of the first wireless communication circuitry based upon the first measure by the computer; and

issuing a first alert by the computer in response to movement of the peripheral device away from the preferred location and at least within a first threshold distance of the first wireless communication circuitry.

21. The method of claim 20 , further comprising:

receiving a second signal from the beacon by second wireless communication circuitry coupled to a computer;

determining a second measure of the second signal by the computer;

determining a second distance from the second wireless communication circuitry based upon the second measure by the computer;

determining that the device has moved away from the preferred location and at least within a second threshold distance of the second wireless communication circuitry based upon the second measure by the computer; and

issuing a second alert by the computer.
