The rfid, Radio Frequency Identification technologies, allow non-contact reading for automatic identification and data capture.
Radio Frequency Identification is a wireless AIDC system that excels in environments where traditional bar code labeling could not survive.Depending upon the type of transponders and interrogation hardware used, line-of-sight interrogation and close proximity are unnecessary with rfid.

This site, sponsored by AIM, is a link to happenings in the Radio Frequency Identification world. The AIM, the Association for Identification and Data Capture Technologies, website provides Radio Frequency Identification information and products, resources, and information on case studies and common applications. Radio frequency identification first appeared in tracking access applications during the 1980's. These wireless AIDC systems allow for non-contact reading and are effective in manufacturing and other hostile environments where bar code labels could not survive. Radio Frequency Identification has established itself in a wide range of markets including livestock identification and automated vehicle identification (AVI) systems because of its ability to track moving objects. The following describes key attributes and limitations of Radio Frequency Identification. The rfid expands the growth area of automatic identification and data capture. With the new generation, lower cost transponders, Radio Frequency Identification offers multi-read capabilities. It includes read/write electronic storage technology. Currently, a wide range of products is available to satisfy a wide range of data storage and data transfer needs. Depending on the product selected, rfid offers low to reasonably high (64K bits) data storage capability. Radio Frequency Identification's have a wide range of data transfer rates, depending on the device and carrier frequency used. Generally speaking, the higher the carrier frequency the higher the data transfer rates achievable. Depending upon the type of transponders and interrogation hardware used, Radio Frequency Identification allows between close proximity (inductive systems) to tens of meters (radiating systems), without the need for line-of-sight interrogation. Robust constructions are available, allowing for use in reasonably harsh conditions. The first International Radio Frequency Identification standards for Item Management (ISO 18000) will be available in early 2003. Your company can purchase Radio Frequency Identification products in order to comply with this standard.
For environments where traditional labeling techniques cannot survive, rfid is an effective and efficient solution for your tracking access application needs.
