Overview - 433 MHZ. RFID Key Fob Tag Active

The Wavetrend KeyFOB Active Tags are powered by an internal battery. The Tag will, for the duration of its life, transmit a Radio Frequency (RF) signal at a pre-set time-interval. The KeyFOB can also be operated in silent mode, with transmissions only occurring upon the press of the button. The Tag life is estimated at 4.8 years at a transmission time interval of approximately 1.5 seconds.

Button pressed transactions will either be logged when out of reader range, or be reported immediately when within reader range. The lifespan of the Tag ends when the battery life is exhausted. Battery status can be inferred by interrogating the internal Tag Age Counter Value.

The transmitted Tag data includes Customer Site Code (CSC), Tag ID, Tag Age Counter Value, Button Alarm status. For protection against adverse environmental conditions, the Wavetrend KeyFOB Tag is encapsulated in a moulded Nylon case. The Tag can be configured to accommodate Wiegand interfacing.

Features - 433 MHZ. RFID Key Fob Tag Active

  • Configurable settings, including Site / Vendor ID, Tag ID and Transmission Repetition Interval.
  • Low power consumption. Tag life is estimated at 5 years when transmitting at a 1.5-second interval.
  • Randomized time-slots (Standard percentage deviation) minimize collisions.

Applications - 433 MHZ. RFID Key Fob Tag Active

Wavetrend KeyFOB Tags can be used in applications where door/safe keys need to be tracked. Institutions such as prisons, hospitals and government institutions would find this beneficial. The KeyFob Tag is also used in personnel tracking and vehicle immobilizing / driver identification applications, where it replaces the Wavetrend personnel tag. For people safety applications in dangerous industrial and construction environments, such as mining, the tag can be used both as a tracking device and a distress-signaling device in case of emergency situations.
