RFID Potential Application: Radio Frequency Identification

Radio Frequency Identification

... "The potential applications for this technology are numerous. RFID technology offers inexpensive read-only tags, which are generally short range (a few inches to a few feet), or more expensive long range, read/write devices with large memory capacities. The short range tags can be used in lieu of bar codes for identifying objects in harsh environments. For example, these tags are used in factories to track items through their production cycle. Given the short read range of these tags, the item typically travels on a conveyor bringing it in close proximity to the interrogator. Short range systems are also used for personal identification and access control operations. The identity of the individual can be determined either with a very short range RFID card reader when held within a few inches of the reader, or with somewhat more expensive systems which can read the card even when it is kept in a pocket.
