Strictly speaking, RFID is not a new concept, it has been used in many edge areas for a long time. It is only under the wave of global economic integration and driven by the concept of supply chain management that RFID has become so hot. The author has been paying attention to the latest development of RFID for more than a year. After calmly thinking, he found that many people's understanding of RFID has fallen into several misunderstandings:
Myth 1: RFID is more advanced than BarCode (barcode), which can improve China's logistics development level.
Frankly speaking, the author has not always been a follower of new technologies, and always believes that the development level of information technology (note: not the application level of information systems) has not yet become a limiting factor for the development of China's logistics. The author absolutely does not doubt that RFID has a great advantage over BarCode in terms of efficiency and accuracy, but the key issue is not to compare whether RFID is more technologically advanced than BarCode. What technology? When we are still worried that the supplier cannot provide barcodes for each product or even at the pallet or box level, when most of our companies do not know what RF is, when the cost of a barcode label When 5 points or 1 cent is difficult, you can imagine how unrealistic it is to implement RFID in China's logistics industry.
It is one of the low-value consumables with high usage rate. It is generally installed on a dry foam rack with the package or in bulk. When used, it is taken out by the operator and placed on the plastic centrifuge tube rack in the ultra-clean workbench. The common centrifuge tube rack can only make the centrifuge tube stand upright. When transferring liquid or needing centrifugation, the operator should hold the centrifuge tube in the left and the night gun or aspirator in the right. If it is necessary to transfer a large amount of liquid reagents or perform gradient centrifugation operations, such as density gradient centrifugation to separate mononuclear cells, the operator needs to hold the centrifuge tube with the right hand for a long time and tilt the centrifuge tube, which often causes the operator's wrist joint pain. At the same time, it will also affect the liquid superposition effect, which will easily lead to the mixing of liquids of different densities, resulting in the failure of the experiment.
Misunderstanding of RFID technology
RFID (Radio Frequency Identification Technology) seems to be the hottest term in China's logistics field in the past year. Large and small logistics exhibitions, summit meetings, various magazines and periodicals, all must say RFID, RFID seems to have become a fashion. There are also many experts and scholars from abroad, domestic, professional and non-professional who are welcoming this revolution with great enthusiasm, looking forward to the bright future of RFID. Sharp weapon.
