The present invention relates generally to an anti-theft system and more particularly to a system for identifying and tracking skis and snowboards. Depending on their quality, skis (“skis” refers to both skis and ski boards) and snowboards can be fairly expensive. Despite this, skis and snowboards are frequently left unattended by their owners. Specifically, ski/snowboard resorts typically have buildings at spaced locations on a hill at which skiers may stop to rest and take refreshment. Skiers and snowboarders remove their skis and snowboards before entering these buildings, and leave their skis and snowboards outside. As a result of skis and snowboards being left unattended, there is an increased possibility of theft. Prior art devices have been devised to address this problem. For example, U.S. Pat. No. 5,001,461 (Vroom et al) discloses a battery operated motion sensor that is attached to a ski and transmits a radio signal if the ski is moved. A receiver, which can be worn around the neck of the owner of the ski, receives the alarm signal and indicates an alarm condition using, for example, an audible beep. Similarly, U.S. Pat. No. 4,535,322 (Yeski) discloses a battery operated audible signaling device which is activated if a clip is detached. U.S. Pat. No. 6,020,818 (Chittenden) and U.S. Pat. No. 5,260,689 (Merers et al) disclose battery powered devices mounted on skis that emit alarms in appropriate circumstances. All of these battery powered devices may suffer from disadvantages associated with the use of a battery. Specifically, batteries are both expensive and require recharging periodically. This can be inconvenient for the owner, and it is not unlikely that owners will deliberately forego the additional expense and inconvenience associated with having batteries mounted on their skis or snowboards, despite the anti-theft advantages battery-powered devices provide. Further, if the skis or snowboards are ever stolen, the battery operated signaling device does not provide a means of tracking the skis or snowboards, and, accordingly, does not allow for eventual recovery of the skis or snowboards. Thus, an anti-theft system for skis that does not rely on batteries and permits the skis to be identified and tracked even after they have stolen, is desirable. An object of one aspect of the present invention is to provide an improved recreational item. In accordance with an aspect of the present invention there is provided a recreational item for sliding on inclined snow-covered surfaces. The recreational item comprises an integral ID storing means for storing an item ID. The item ID is electronically readable from the integral ID storing means. Preferably the integral ID storing means is a transmitter. In the preferred embodiment, the transmitter is a transponder and the item ID stored thereon is unchangeable. In accordance with a second aspect of the present invention there is provided a system for tracking a plurality of recreational items for sliding on snow-covered surfaces of a hill. The system comprises, for each item in the plurality of recreational items, an associated integral ID storing means for storing an associated item ID, the associated item ID being electronically readable from the associated integral ID storing means. The system also comprises an interrogator means for reading the associated item ID stored on the associated integral ID storing means for each item in the plurality of recreational items. Preferably, the associated integral ID storing means for each item in the plurality of recreational items is a transmitter. In the preferred embodiment, this transmitter is a transponder. According to a further preferred aspect of the present invention, there is provided a system for tracking a plurality of recreational items for sliding on snow-covered surfaces at a plurality of locations. Each location in the plurality of locations has an associated user transport means for transporting an associated set of users of an associated set of recreational items in the plurality of recreational items. The system includes, for each item in the plurality of recreational items, an associated transponder for unchangeably storing an associated item ID, the associated item ID being electronically readable from the associated read only transponder. This system also includes, for each item in the plurality of recreational items, an associated card having a magnetic strip for electronically storing the associated item ID for the item. This system includes, for each location in the plurality of locations, (a) an associated interrogator means for reading the associated item ID stored on the associated transponder for each item in the associated set of recreational items, the associated interrogator means being located within a reading range of the user transport means, and, (b) a card-reading means for reading the associated item ID from the magnetic strip of the card for a recreational item in the plurality of recreational items. Further, the system includes a server for storing a list of item IDs, the server being linked to the associated interrogator means for each location in the plurality of locations and to the associated card reading means for each location in the plurality of locations. The system further includes an ID verification means for checking each associated item ID read by the associated interrogator means for each location in the plurality of locations against the list of item IDs stored on the server, and, alarm means for indicating when the associated item ID read by the associated interrogator means for each location in the plurality of locations corresponds to an item ID stored in the list of item lDs. A detailed description of the preferred embodiments is provided herein below with reference to the following drawings in which: Referring to Referring to Both skis and snowboards are typically constructed by laminating different materials on top of a core material. To impede its removal, the transponder 24 is preferably embedded deep within the ski 20 or snowboard 22, between different layers of laminate. Referring to Each snowboard 22, and each pair of skis 20 is manufactured with a transponder 24 as an integral part thereof such that the transponder 24 cannot readily be removed from the ski 20 or snowboard 22. At some point during or after the manufacture of either the snowboard 22 or the skis 20, the identification number 28 is written on the transponder 24. The transponder 24 is of the type that cannot be subsequently re-written; accordingly, the identification number 28 stored on the transponder 24 is thereafter fixed. When the snowboard 22 or skis 20 are sold, the owner also receives the identification card 26 on which is stored the same identification number 28 that is stored on the transponder 24 of the snowboard 22 or skis 20. Referring to Referring to Referring back to Referring to If a skier reports the loss of his skis and produces a card 26, the identification number 28 stored on the card 26 is scanned using the card reader 56. This identification number 28 is then uploaded to the server 44, and will subsequently be downloaded to all resorts (computers 40) connected to the server 44 so that the ID verification module 48 will check the identification number 28 against all identification numbers read by all of the RFID interrogators for that resort. The identification number 28 may also be accessible to appropriate law enforcement agencies to assist them in their investigations and to facilitate recovery of stolen property. If a card 26 has been lost, then the owner of the skis or snowboard may still have the identification number 28 uploaded to the server, provided the owner can prove ownership of the skis or snowboard having that identification number. This can be done, for example, by providing a purchase receipt to the authorities on which the identification number is written. Preferably, the owner's name will also be written on the card 26 and the owner will have to produce identification proving the owner is the person named on the card 26 before reporting the skis or snowboard to be missing. The present invention may be embodied in other specific forms without departing from the spirit or essential characteristics. Certain adaptations and modifications of the invention will be obvious to those skilled in the art. Therefore, the presently discussed embodiments are considered to be illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.FIELD OF THE INVENTION
