Active RFID Information

Some advantages of an active RFID tag are:

  • It can communicating data at distances of as far as 300 feet.
  • It may have other sensors that can use electricity for power.
  • Active tags are capable of operating in rugged environments for years at a time.
  • Active tags are battery-powered, and can either transmit constantly or be activated by a signal from the reader.
  • The capability of performing diagnostics
  • the capability to perform independent monitoring and control
  • the capability of initiating communications

Some disadvantages of an active RFID tag are:

  • Cannot function without battery power, limiting the lifetime of the tag.
  • Typically much more expensive than passive RFID
  • The tag is physically larger, which may limit applications.
  • Potential long-term maintenance costs for an active RFID tag if the batteries are replaced.
  • Battery outages in an active tag can result in misreads.

Uses of active RFID tags include:

  • Tracking high-value work in process (WIP) inventory in the aerospace and automotive manufacturing sectors
  • Tracking trailers and containers in the transportation industry, both inside a warehouse and around the depot.
  • In conjunction with GPS or GSM for locating people or things
  • With Bluetooth to locate personnel in facilities (locating doctors in hospitals, for instance)
  • Active RFID enhanced phones
  • Animal tracking
  • Security ID badges
  • Track and locate valuable assets in the healthcare, manufacturing and logistics markets
  • Health care applications- tags can be used on patients, personnel and expensive hospital equipment.
