RFID Solutions… identifying through radio waves
Radio Frequency Identification (RFID) which is similar to Bar-Coding in some aspects, as both are auto-ID technologies, is intended to provide rapid and reliable item identification and tracking capabilities. The primary difference between the two technologies is the way in which they read objects. With bar coding, the reading device scans a printed label with optical laser or imaging technology. Whereas, with RFID, the reading device scans, or interrogates, a tag using RF signals. RFID Technology is a reliable choice for automatic data capture.
Radio frequency identification, or RFID, is a general term for technologies that use radio waves to automatically identify people or objects. There are several methods of identification, but the most common is to store a serial number that identifies a person or object, but also other information, on a microchip that is attached to an antenna (the chip and the antenna together are called an RFID transponder or an RFID tag). The antenna enables the chip to transmit the identification information to a reader. The reader converts the radio waves reflected back from the RFID tag into digital information that can then be passed on to computers that can process information from it..
