■ CLASS 0: passive, read-only tags (programming is carried out by the semiconductor manufacturer) ■ CLASS 1: passive tags which can only be written once ■ CLASS 1 GENERATION 2: passive tag which can be written several times ■ CLASS 2.4: other definitions for semiactive and active systems Tags of CLASS 1 GENERATION 2 (usually abbreviated to GEN-2) are the most important data carriers.
EPC divides the tag specifications and the standards for the air interface into different classes: In this context, a series of RFID technologies are defined which were once based on proposals by members but are now being developed by EPCglobal's own special action groups. For manufacturers of RFID systems, the radio standards of EPCglobal are extremely important. The ranges of EPC numbers are allocated by GS1. GS1 also participates in projects for the further integration (of data) in trade, e.g.
#SIEMENS SIMATIC RF660A LICENSE#
Companies which want to introduce such numbering systems must obtain a license from GS1 for a specific range of numbers. The main task of GS1 is the administration and allocation of internationally used numbering systems such as the European Article Number (EAN). EPCglobal is sponsored by GS1 International and its national off-shoots. Apart from technical standardization, there are so-called "Business Action Groups", which deal with the use of EPC in different branches of industry. METRO or Walmart), are members of EPCglobal.
#SIEMENS SIMATIC RF660A SOFTWARE#
All well-known manufacturers of RFID systems, including the large software companies, and many RFID users (e.g. EPCglobal mainly consists of a series of bodies which promote and lend impetus to the development and standardization of all the technologies needed for RFID in logistics and trade. EPC is the brainchild of EPCglobal, located in the U.S.
#SIEMENS SIMATIC RF660A CODE#
The Electronic Product Code (EPC) itself is only one part among a large number of activities and technologies. EPC stands for Electronic Product Code – but what does it actually mean? EPC is synonymous with a new level of development in the field of RFID systems: spectacularly inexpensive tags (price < 0.15 EUR for large quantities), excellent performance data and worldwide standardization of the protocols and applications are enabling new applications for RFID in intralogistics, supply chain management and trade. The latest generation of RFID components from Siemens, the SIMATIC RF660 Portal Readers, now also support the GEN-2 EPC standard.
