1.1. EPC standards development process
1.2. EPC standards development progress(2005-Feb-14)
2. ISO 18000
Management of goods belonging to the standard, mainly used in supply chain management. ISO in particular by the ISO / IEC JTCI/SC31 group planning a series of 18,000 of the standards such as ISO18000-3 for 13.56MHz standard, ISO 18000-6 protocol for UHF.
As a result of supply chain management is the world's attention to a business exploits, so in addition to ISO 18000, the Massachusetts Institute of Technology in 1998 also began to study the establishment of a unique identification system, and in October 1, 1999 with the UCC (Uniform Code Council), P & G, Gillette and other organizations and the private sector to set up a MIT Auto ID Center, trying to develop a combination of RFID technology, network technology, the world-wide standard information platform. Finally, they proposed, is a recent comment by the EPC (Electronic Product Code) structure. The system will be equivalent to ISO 18000-6 standards.
However, ISO 18000-6 is more than the EPC system applications. ISO norms are mainly due to their "common language" standard (that is, Air Interference Protocol), without taking into account the label and read the data content and practical application, it does not consider the structure of its infrastructure (such as network technology and information application platform ), the specifications simply under the label of the data transmission media, a word is their estimate of the baseline specification as defined in less than the EPC system.
3. ISO 15693 (ISO SC17/WG8) - short-range RFID card
Standards to the farthest distance of 1.5 meters to read non-contact type RFID cards. Its simple design make it far more reader ISO 14443 low-cost, easy to use and as a result of tracking, so ISO 15693 is mainly for access control, attendance, etc.. Its disadvantage is that the communication speed of only 26K bits.
4. ISO 14443A (ISO SC17/WG8) - Ultra-short-range RFID card
Read this standard from the farthest in the 7-15mm within the scope of standards, an ultra-short distance non-contact type RFID cards. Mainly used in public transit use voting cards. There are two schools of this technology, including Infineon developed by Phillips and Mifare, and Inside Contactless provided by PicoPass version A.
5. ISO 14443B
ISO14443A use with the same ISO 14443B but more than the benefits of ISO 14443A, including the modulation depth is only 10% of the general micro-processor benchmarks, the communication speed of up to 847 KHz, there had been no communication between the key patent issues, it is becoming Reader production plants tend to use standard, but also Japan, China and the United States to adopt standards.
