RFID UHF PASSIVE READERS
Radio-frequency identification (RFID) is the wireless use of electromagnetic fields to transfer data, for the purposes of automatically identifying and tracking tags attached to objects. The tags contain electronically stored information. Some tags are powered by electromagnetic induction from magnetic fields produced near the reader. Some types collect energy from the interrogating radio waves and act as a passive transponder. Other types have a local power source such as a battery and may operate at hundreds of meters from the reader. Unlike a barcode the tag does not necessarily need to be within line of sight of the reader, and may be embedded in the tracked object. Radio frequency identification (RFID) is one method for Automatic Identification and Data Capture (AIDC).
RFID tags are used in many industries.
Cardtec provides a range of RFID readers and tags for various applications.
RFID provides a way for organizations to identify and manage tools and equipment (asset tracking), without manual data entry. RFID is being adopted for item level tagging in retail stores. This provides electronic article surveillance (EAS) and a self checkout process for consumers. Automatic identification with RFID can be used for inventory systems. Manufactured products such as automobiles or garments can be tracked through the factory and through shipping to the customer.
