Interpretation of the application of rfid technology in jewelry industry management

　　my country's jewelry industry has a long history. However, due to the late start of modern technology and poor foundation, most domestic jewellery companies only have small and medium scale, with outdated equipment, backward technology and technology, and low production efficiency. Their survival depends on the huge domestic market demand, not their own strength and competitiveness. The opening up of China's jewelry market has brought unprecedented opportunities for the development of China's jewelry industry. At the same time, it has also created severe challenges and pressures on the increasingly competitive domestic jewelry industry. my country’s jewelry industry urgently needs to introduce advanced production and management technologies to improve its competitiveness.

　　As an advanced automatic identification technology, RFID technology has been integrated into economic and social development in all directions, multiple angles, wide areas, and deep levels, especially in the fields of personnel management, asset management, and intelligent transportation. It can be said that RFID technology has injected a new vitality into the information society. This article will study the application of RFID technology in the jewelry industry based on the characteristics and needs of my country's jewelry industry.

　　The choice of RFID system is the basis of the application. According to the energy supply mode of the radio frequency tag, RFID tags can be divided into active, passive and semi-active tags. Active tags use the energy of the battery in the card, and the recognition distance is longer, up to tens of meters, but its life is limited and the price is relatively high; passive tags do not contain batteries, and use the electromagnetic field energy emitted by the reader as their own Energy, its light weight, small size, life span can be very long, very cheap, but its launch distance is limited.

　　Active and passive have their own advantages and disadvantages, and the four frequencies have their own characteristics. Different combinations are suitable for different products and environments. In order to select an RFID system suitable for jewelry shops, the application of RFID technology must consider the characteristics of jewelry, business requirements, and management cost control:

　　Broadway Smart recently launched a jewelry antenna, the BRA-09 antenna, which is specially designed and developed for jewelry. It is mainly suitable for near-field antennas of UHF frequency band RFID in various applications. It has the characteristics of uniform field, large size and ultra-thin without blind areas. With it in the jewelry industry, all problems are no longer a problem.

　　1. Consider the characteristics of jewelry

　　Jewelry is a metal product, which means that RFID tags will be used in metal environments. At this stage, there are three methods for marking metal parts. One is the method of isolating the metal and the label used in high frequency and low frequency, and the cost is relatively high; the other is to design the label reasonably so that the label antenna is at an appropriate distance from the metal surface; The third type is to attach the label, including the method of hanging a label, and carrying the label on the non-metallic tray or container of the label. Since there is a badge printed with jewelry information on the jewelry, the label can be directly attached to the badge, so various frequencies can be applied, and the detuning of the RFID tag on the metal surface does not affect the application.

　　2, considering business needs

　　Whether it is warehouse management or personnel management, it is necessary to read a large number of tags at the same time in all directions. This requires that the RFID system must have a faster reading speed, and there is no restriction on the directionality of reading tags. Although the low-frequency system has no directional limitation, the reading and writing speed is slow. The reading and writing speed of UHF and microwave systems can meet the requirements, but there are some directional limitations. Only the high frequency can meet the requirements in the reading speed, and there is no reading. Take the directional development of the label.

　　3, from the perspective of management cost control

　　The active tag has a long identification distance, but its life span is only 2-5 years, the price is high and the maintenance is inconvenient. Passive tags are light in weight, small in size, and have a very long life of up to 15 years and are cheap, but the reading distance is limited. Although the application of active tags can reduce the number of readers installed, its own price and maintenance costs are much higher than passive tags, and the weight and volume of active tags are not suitable for use on jewelry brands.

　　Comprehensive analysis of various aspects, the high-frequency passive RFID system has the characteristics of small tag size, low cost, high reading speed, moderate reading distance, and strong anti-metal interference ability, which is suitable for the jewelry industry. Broadwell Smart BRA-09 antenna is specially designed and developed for jewelry. Independent product research and development is the best partner for intelligent jewelry management.
