Security system
First Claim
1. A monitoring system which includesa primary electronic tag including primary identification data and associated with a primary bearer of the tag;
- a secondary electronic tag including secondary identification data and associated with a secondary bearer of the tag, the secondary identification data being associated with the primary identification data;
reading apparatus for remotely reading the primary identification data from the primary identification tag and remotely reading the secondary identification data from secondary identification tag; and
comparator means operable to compare the secondary identification data and the primary identification data and generate an output signal dependent upon an outcome of the comparison.

Abstract
A monitoring system 10 is provided which includes a primary electronic tag 12, a secondary electronic tag 16, reading apparatus 20, and a comparator 26. The primary electronic tag 12 includes primary identification data associated with the primary bearer 14 of the tag 12 and the secondary electronic tag 16 includes secondary identification data. The secondary identification data is associated with a secondary bearer 18 of the tag 16 and is also associated with the primary identification data. The reading apparatus 20 remotely reads the primary and secondary identification data and the comparator 26 compares the data and generates an output signal dependent upon the outcome of the comparison. The invention extends to a primary electronic tag 12 for use in monitoring movement of at least one secondary electronic tag 16. The invention also extends to a method of monitoring movement from a selected zone and a method of monitoring the use of at least one vehicle.

15. A method of monitoring movement from a selected zone, the method including
reading primary identification data from a primary electronic tag issued to a primary bearer of the primary electronic tag; -
reading secondary identification data from a secondary electronic tag associated with a secondary bearer of the secondary electronic tag, the secondary identification data being associated with the primary identification data which defines authorised movement of the secondary bearer; and
comparing the secondary identification data and the primary identification data to monitor movement of the secondary bearer from the selected zone. - View Dependent Claims (16, 17, 18, 19)
issuing the primary electronic tag to a person supervising at least one child; issuing a secondary electronic tag to the child, the secondary electronic tag including unique identification data to identify the child and which is intermittently transmitted;
programming the primary electronic tag with the primary identification data and the secondary electronic tag with the secondary identification data; and
generating an alarm signal when the child and the supervisor are not in the same zone.

18. A method as claimed in claim 17, in which a plurality of children are each issued with a secondary electronic tag and the primary identification data includes an inventory of the secondary electronic tags with which it is associated.
-
19. A method as claimed in claim 15, which includes controlling operation a security control arrangement in response to the comparison selectively to inhibit departure of the primary bearer from the zone.
-
20. A method of monitoring the use of at least one vehicle, the method including
issuing a primary electronic tag including primary identification data to a person authorised to drive a particular vehicle; -
providing the vehicle with a secondary electronic tag which includes secondary identification data associated with the primary identification data;
reading the primary and secondary identification data in a wireless fashion when the person occupies the vehicle; and
comparing the primary and secondary identification data thereby to monitor use of the vehicle. - View Dependent Claims (21)
