Differences between the iso18000-6b and iso18000-6c (EPC c1g2) standards

Currently, there are two criteria to choose from. One is iso18000-6b, and the other is the EPC C1G2 standard that has been accepted by ISO as ISO18000-6C. These two standards, each have advantages. ISO18000-6B Standard is located in the general standard, the application is more mature, the product performance is relatively stable, the data format and standard is relatively simple. The main features of the ISO18000-6B Standard include: standard maturity, product stability, wide application, ID number is unique globally, read ID number, post-read data area, 1024bits or 2048bits large capacity, 98Bytes or 216Bytes large user data area, multi-label simultaneous reading, Up to dozens of tabs can be read at the same time, with a data read speed of 40kbps. The electronic label conforms to the ISO18000-6B standard mainly applies in the field of asset management. At present, the domestic development of the container logo electronic tags, electronic license plate label, electronic driver's license (driver card) are using this standard chip. According to the characteristics of the iso18000-6b standard, from the reading speed and the number of labels, in the bayonet, dock operations and other labels in a small number of applications, the application of ISO18000-6B standard label to meet the needs of the basic. At present, the "electronic license plate recognition system" used in China's Customs logistics regulatory system is the ISO18000-6B standard electronic label.
ISO18000-6B the shortcomings of the standard is: In recent years, the development of stagnation, has been replaced by the EPC C1G2 trend; The software curing technology of user data is not mature, but this kind of situation can be solved by embedding user data into the chip manufacturer. ISO18000-6C (EPC c1g2) Standard This standard is characterized by: fast speed, data rate of up to 40kbps~640kbps, can read more than the number of labels, theoretically can read more than 1000 tags; first read the EPC number, the ID number of the tag needs to read the data read the way , strong function, with a variety of write protection, security strong, the region is divided into the EPC zone (96bits or 16Bytes, can be extended to 512bits), the ID area (64bit or 8Bytes), the user area (224bit or 28Bytes), the password area (32bits or 4 Bytes), but some vendors provide labels that do not have user data areas, such as Inpinj.
EPC C1G2 Standard is mainly applied to the identification of large quantities of goods in the field of logistics, and is in continuous development.
The EPC C1G2 standard has many advantages, such as strong universality, conformity with EPC rules, low price of product, good compatibility and so on, but the following problems need to be considered:
1, the standard label products and applications are not mature, the current label is more air medium.
2, the user data area is small, only 28 bytes, for the container logo electronic label, if you need to write the container data defined by ISO10374, the data area capacity is not enough.
3, at present, the chip used for EPC label is almost all Daotie tablets, the chip can be welded package is very few. Daotie tablets of the process for many years of work outdoors, sports, bumpy goods, reliability is difficult to guarantee.
4, EPC c1g2 electronic label positioning in the Universal label, too the pursuit of low price, its chip design and packaging design of the product's environmental adaptability to consider weaker, such as the application of the container logo electronic label environmental suitability requirements, longer service life, the field of application of relatively professional fields, chip technology, performance, The process needs to be further improved.
5. The standard contains self-destruct procedures, which require careful consideration for the transport of containers, which are used for long-term mobility. According to the above analysis, the ISO18000-6B standard electronic label technology, application is more mature, such as the application of container labels, product, practical steps can be faster; for EPC C1g2, first of all, to solve the chip technology, performance, technology and other issues, need to get the strong support of chip manufacturers at home and abroad, The time of practical popularization is unpredictable.
