Even though RFID (Radio Frequency Identification), has been around since the second world war, it is only in the last two years that it has become a viable alternative to other forms of asset tagging.
There are several reasons that RFID is now viable:
- The tags are cheaper
- The readers are more powerful with longer read range
- The tags are not as sensitive with respect to the materials they are placed on.
- The readers are cheaper
There are two types of RFID tags, Passive (no battery) and Active (battery powered). The major benefit of RFID tags is that they do not require line of sight to be registered. Hardcat caters for the reading of these tags via fixed readers (door way) as well as via handheld PDA units.
There are two programs for the PDA:
- Popcorn Audit – the ability to perform thorough rapid audits.
- Search and Find – the ability to use the PDA like a Geiger counter when searching for certain assets. The closer you get to the asset the louder the clicking becomes.
In a pilot site for South African Defence, an audit of parachutes that normally took three months was performed in two hours with Hardcat’s RFID solution.
