  • RFID Glossary : Reader collision occurs

    Reader collision occurs in RFID systems when the coverage area of one RFID reader overlaps with that of another reader. This causes two different problems: Signal interference The RF fields of two or

  • RFID Glossary : RFID Tag Collision

    Tag collision in RFID systems happens when multiple tags are energized by the RFID tag reader simultaneously, and reflect their respective signals back to the reader at the same time. This problem is

  • RFID Glossary : RF Fibers

    RF fibers, also known as chipless RFID, is a kind of RFID tag that does not make use of any integrated circuit technology to store information. Fibers or materials are used that reflect a portion of t

  • RFID Glossary : RFID Reader

    An RFID reader is a device that is used to interrogate an RFID tag. The reader has an antenna that emits radio waves; the tag responds by sending back its data. A number of factors can affect the dis

  • RFID Glossary : Transponder for RFID

    An RFID transponder is a special kind of radio transmitter and reciever. It is activated when it receives a signal of a specific kind. RFID transponders are present in smart cards and Radio Frequency

  • RFID Glossary : Smart cards

    Smart card is another way to refer to a contactless smart card. This term refers to identification cards (for example, some credit cards) that do not need to make contact with the reader to be read, o

  • RFID Glossary : Smart label (RFID Smart Label)

    A barcode label that contains an RFID transponder is called an RFID smart label. Since the label is able to store information (like a serial number) and communicate with an RFID reader, it is consider

  • RFID Glossary : Passive RFID Tag (or Passive Tag)

    A passive tag is an RFID tag that does not contain a battery; the power is supplied by the reader. When radio waves from the reader are encountered by a passive rfid tag, the coiled antenna within the
