Radio frequency identification (RFID) is an automatic data capture (ADC) technology that comprises small data-carrying tokens ('tags'), and fixed or mobile scanners ('readers'). Tags are attached to or embedded in objects to be identified.
Readers may be installed at locations where data capture is required, and may also be in the form of portable readers. Data captured from tags is transferred between distributed readers and a host environment via wire or wireless serial communications links.
Readers and tags communicate using low power radio frequency (RF) signals. Tags typically are based on a custom designed silicon integrated circuit. Data may be read from and written to tags by readers.
Through the application of RFID, items may be tracked automatically and without human intervention, minimizing time involved in identification processes, and with high integrity of data capture.
RFID technology providers are working to create RFID-capable product platforms that will enable its customers to benefit from integrated technology solutions employing an optimum mix of RFID, 1D and 2D bar code technologies.
RFID is harnessed as a core component to allow retailers to more efficiently track consignments and items from manufacturers, through distribution channels to the retail store. Other opportunities that Symbol and its partners are already pursuing include military logistics, parcel and postal service logistics, transportation fleet management and corporate asset control.
