1, from jewelry to consider the characteristics of the
Jewelry is a kind of metal products, that is to say the RFID tag will be applied to the metal in the environment. There are three ways of metal logo at the present stage, is amethod in the isolation of metal and label the high frequency and low frequency used, the cost is relatively high: another is the rational design of tag, the tag antenna away from the metal surface proper distance;third is attached identifier, including listing Zi, logobearing in identified the non metal tray or containerclassy way. Because jewels had a printed jewelry information card Zi, the label can be directly attached to the card carefully, so that various frequency can be used,the RFID tag does not affect applications in themismatching problem of metal surface.
2, from the business needs to consider
Both warehouse management or personnel management,requires a full direction at the same time read large number of labels, which requires the RFID system must have read faster, and no read labels without directionrestriction. The low frequency system although no directional limit but the reading and writing speed is slow,UHF and microwave system to read and write speed can meet the requirements but some directional constraints,only the high frequency can meet the requirements inreading speed development direction, also did not read the labels.
3, from the management cost control considerations
Active tag identification distance is longer, but its limited life only 2 - 5 years, high price and inconvenient maintenance. Passive tags of light weight, small volume,long life can be up to 15 years and cheap, but reading distance co.. Although the application of active tags canreduce the number of installed reader, but its price and maintenance cost is much higher than that of passive tags, and tag weight and volume were not suitable for use in jewelry brand Zi.
Analysis of various aspects of the comprehensive, high frequency passive RFID tag system has small volume, low cost, high reading speed, reading distance is moderate,the ability of anti interference characteristics of metalstrong, suitable for use in jewelry industry.
