RFID tagging – Audits not requiring line of sight to be registered.
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 or labelling.
There are several reasons why RFID is now viable
- Tags are cheaper to purchase
- Readers are more powerful with a longer read range
- Tags are not as sensitive with respect to the materials they are placed on
- Readers are cheaper to purchase
There are two types of RFID tags, Passive (no battery) and Active (battery powered). The major benefit of using 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 (doorway) 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.
