mikoh&rsquos securecontainer system provides a passive tag, which is designed to inform an rfid interrogator if a seal of the container has been opened while going through the supply chain. in the first place, the device incorporates an antenna and passive rfid chip. an antenna is connected to the tamper sensor. if anyone tries to damages the sensor or remove the seal, allows the antenna and rfid chip to keep functioning. a sensor is a release coating, which is a layer within the tag construction. atherton mentions that a single bit in the data indicates the tag&39s tamper status. from its original status &39untampered&39 to &39tampered&39 status, once this bit has been changed, it cannot be changed back. when a tag in a damaged sensor is encoded by an rfid interrogator, the tag sends out that tampered status, showing it has been damaged. the second case uses a more basic device, which according to atherton, may be more popular in the commercial market. if any person attempt to tear or remove the tag, its antenna would get damaged and its bond to the rfid chip would be conked out. in such a condition, that container&39s tag cannot be decoded by an rfid interrogator. as compared to a regular rfid container tag, the cost of the first option would be about 50 percent higher, he mentions, while the price of the basic alternative would be 10 to 20 percent bigger. a reusable plastic container, securecontainer is typically measuring 15 by 12 by 5.5 inches. however, this container is also available in other sizes, as well. the container features one point of entry. this entry could be in the form of two doors at the peak of the container, which are secured and closed with an adhesive seal. this seal will have an integrated smart&secure passive rfid tag. the securecontainer has been created for checking by government organizations using 915 mhz or 13.56 mhz rfid chips however, the tags are offered in an extensive range of airinterface standards and frequencies to fulfil the requirements of each end user. even though the seals use passive tags, atherton mentions, mikoh is also checking the system with semiactive tags. the seals can abscond behind a remainder after use, making it hard to apply a new seal on it. as a result, mikoh developed the securecontainer in such a manner that the seal attaches to disposable plastic insert which slide into the container&39s doors. at the end of the shipment, the inserts can be removed leaving a spotless exterior for the next shipment. mikoh&39ssecurecontainer, according to atherton, consisting of the seal and container, is commercially offered now, with no specific software needed. source of information httpwww.rfidjournal.comarticlesview30502
