Britain continues to tap low-cost RFID Technology Smart packaging
not long ago, Tesco, a British supermarket chain giant, used RFID systems to monitor its stores to see who picked up the "Gillette" razor and blade. In the experiment, each pack of razors contained an RFID tag, which was connected to a receiver in the store, and the receiver was connected to a network camera, through which the customer who picked up the razor was photographed
at present, when straightening, the structure of the rocker arm drop hammer impact tester is shown in Figure 1, and the wire surface must not be damaged. RFID is still in the development stage, and even blunt labels are quite expensive. RFID is mainly used in the supply chain to label inventory goods rather than single items. RFID is expanding to high priced goods, so the cost of RFID can be easily offset. Moreover, even if the cost of a passive RFID tag is less than 1 euro cent, attaching this tag to a can of 30 euro fried beans will consume all the profits of this product
the biggest application of RFID technology may be in intelligent packaging. For example, Swedish company cypak invented a kind of printing ink, which can be used on ordinary cardboard, and an RFID system is established on the packaging. This kind of system can be used for drug testing. In drug testing, we need to know the exact time when the patient takes the pills out of the package. Accurate understanding of the opening time of the package is useful for the test. But even cypak has to pay attention to the cost of this system. Smart packaging itself is good, but it is not worth spending a lot of extra cost on it
minimize parts and make use of existing circuit printing technology, so that the cost of packaging materials with RFID function has been low. Cypak found that the cost of the existing RFID reader was too high, so it designed its own reader, which cost only a few euro cents, rather than the accuracy of ten or hundreds of euro cents as mentioned in other reports
the innovative application of RFID technology seems to be the way to find the direction. The research on RFID "micro dust" by the University of Berkeley, Intel and BT also shows the long-term prospect of preparing 2G absolute dry pulp samples according to the rules. In this kind of research, micro RFID tags, as low-energy transceivers, transmit information on demand in a grid way. At present, RFID technology is mainly aimed at military or civil engineering projects that cannot be solved by wired networks and formal wireless networks. In such projects, micro dust can provide a special professional monitoring system
