Description
1 A SECURITY TAG, A METHOD FOR PROVIDING AN ITEM WITH ASECURITY TAG, AND AN ADDITIONAL PART USED FORSUPPLEMENTING A SECURITY TAG Technical FieldThe present disclosure relates to a security tag, a method for providingan item with a security tag and an additional part used for supplementing a security tag.
BackgroundElectronic article surveillance (EAS) systems are commonly used for preventing theft and similar unauthorized removal of items from a controlledarea. The system consists of EAS security tags/labels attached to an item,deactivators and detachers, and detectors that create a surveillance zone atexits or checkout aisles. lf an active label or tag is carried past the detectorsan alarm sounds.
The most common technologies used in EAS systems are AM(Acousto-Magnetic), EM (electro-magnetic), RF (Radio-Frequency) andcombinations of e.g. AM/RF. An article surveillance system may rely on oneor more of these technologies. Likewise, a security tag may have securityelements for use with one or more of these technologies.
The interest for combining the above mentioned technologies withRFID (Radio Frequency Identification)technology is tremendous. ln an RFIDsystem data is transmitted by a portable device, such as a tag or labelattached to an item, which is made up ofa microchip with an antenna. Thedata is then read by an RFID reader or interrogator. Different RFID systemsmay use different frequencies, where the most common are low-frequency,high-frequency and ultra-high-frequency. Microwave is also used in someapplications. The data transmitted by the RFID tag/label may provideidentification or location information, or specifics about the producttagged/labelled, such as price, colour, date of purchase, etc. A retailer mayfor example utilize RFID tagging/labelling of articles for improved inventory visibiiity. 2An EAS system and an RFID system may be combined by adding a separate RFID label to an EAS tagged/Iabelled item and supplementing theEAS detector with an RFID reader. A disadvantage with the use of labels is,however, the risk of unauthorized removal and the risk of the label falling offthe item.
This problem is solved in for example US6144301 andWO2011055157, where an EAS hard tag is combined with an RFID unit into asingle security tag, which is attachable to an item. ln US6144301 an EAS hard tag is shown, wherein an RFID unit isplaced in a drawer which may be slid into a receiving cavity of the EAS tagand mechanically locked in the inserted position within the receiving cavity.The tag body may then be secured to the item by screws or otherconventional securing members. lf the EAS tags of an existing EAS system,which is to be supplied with an RFID system, are not provided with this kind ofdrawers in which to place the RFID units, new EAS-tags with drawers wouldhave to be purchased, which may be costly. ln WO2011055157 a security tag is shown having a stem adapted tobe engaged into a locking mechanism with a part containing an EAS unit, apinhead and a plastic body with an encapsulated RFID unit, which plasticbody fixedly receives the pinhead. The security tag, hence, is comprised oftwo separate parts, one part containing an EAS unit and one part containingan RFID unit, where the two parts are engaged by a pin system. Whensupplementing an existing EAS-tag with an RFID unit, the part of the tag notsupplied with the EAS unit has to be exchanged to a part containing an RFID unit, which may be costly.
Summarylt is an object of the present disclosure to provide a simple and cheap security tag, to provide a method for providing an item with a security tag andto provide an additional part for supplementing a security tag. The invention isdefined by the appended independent claims. Embodiments are set forth inthe dependent claims, in the attached drawings and in the following description. 3According to a first aspect, there is provided a security tag comprising a first member, a second member, a locking mechanism for releasablylocking the first and second members together in a locked position; and atleast one additional part comprising at least one identification element and/orat least one first security element, wherein the additional part at anattachment portion is releasably attached by the locking mechanism.
By releasably locking the first and second members of the tag togetherin a locked position means that they are releasable only under influence of anauthorized unlocking device. That the additional part is releasably attached bythe locking mechanism of the tag also means that it is releasable only underinfluence of the authorized unlocking device above. The first and secondmembers of the tag may be separate members, or may be flexiblyinterconnected by for example a resilient hinge. Alternatively, the first andsecond members could be comprised of one piece having two arms, i.e. thefirst and second members. The locking mechanism may comprise known pinsolutions but may equally well be other kinds of locking mechanisms. Theadditional part is a separate part of the security tag and does not constitute apart of the tag. With this security tag there is therefore no need for anyreplacement, interference or change of the first and second members or thelocking mechanism of the tag to supplement the security tag with additionalsecurity elements and/or identification elements, since this is provided for inthe additional part. An additional part is easily interchangeable to otheradditional parts having a desired functionality. lt is also possible tosupplement the security tag with more than one additional part, the additionalparts being provided with different identification elements/security elements.The item to which the security tag is attached may be any kind ofmerchandise. The security tag may be reusable, if the locking mechanism isof a type which allows for repeated connection and disconnection of the firstand second parts.
