Auto-ID From RFID Technology

Auto-ID technology is implemented in several different ways, including bar-code, lasers, voice recognition and biometrics. These techniques suffer from limitations such as the end for Line of Sight (LOS) with the interrogator (laser and barcodes), low data storage capacities (barcodes) and the need for human intervention (voice recognition and biometrics).

Radio Frequency Identification (RFID) was developed to overcome these limitations. RFID provides an Auto-ID technology that does not require LOS, has a longer read range, can store large amounts of user data using integrated technology and allows changes to the store data.

RFID proves useful when traceability through process or life cycles is required, where data errors are high, such as in material identification or handling, and where business systems need more information than automatic identification technologies like bar coding can provide.

RFID is one of the most promising, rapidly developing, convenient, easy to use technologies, which uses Radio Frequency (RF) signals for automatic identification of objects. It offers the advantage of read/write (R/W) capability without being limited by Line of Sight (LOS) type of propagation.

RFID enable machine to machine communication and event driven communication, where data is provided and processed in real time. RFID using the simplest form of electronics is available in a choice of form and function that is virtually limitless.
