RFID

Bringing Intelligence to Identity Solutions

RFID

Current RFIDs fall into three categories; active, semi-active, and passive RFID tags. Composed of a microchip, antenna, and, in the case of active and semi-passive tags, a battery they are usually enclosed within plastic, silicon or sometimes glass.

Essentially these RFIDs all work in the same way:

Data stored within an RFID tag's microchip waits to be read
The tag's antenna receives electromagnetic energy from an RFID reader's antenna
Using power from its internal battery or power harvested from the reader's electromagnetic field, the tag sends radio waves back to the reader
The reader picks up the tag's radio waves and interprets the frequencies as meaningful data

HRS RFID Solutions

Whilst RFID has been integrated across large projects by governments and some large organisations it is only now becoming small and cost effective enough to be more commercially viable. As such HRS is actively working in close partnership with some of the leading names to introduce commercially robust solutions across the public and private sector for the fusing of objects identity with a person’s allowing for the ultimate pairing of individual and asset.

How are RFIDs Being Used

In recent years there have been several key changes that have driven growth and possibilities for the use of RFID, cost, reliability and size.

The current record held by Hitachi for the smallest RFID chip is at dimensions of 0.05mm by 0.05mm, which is 64 times smaller than the current modern RFID tags. Added to this the costs of equipment and tags has dropped whilst the reliability of the devices to accurately communicate has risen to 99.9%.

With this growing opportunity there are two clear areas that have great benefit from the use of such devices. The technology itself centres around identifications and as such in the real world fits two key business and lifestyle areas, payments and asset management. As such the development and use of the technology is being used to enable tracking of goods through transportation and payments in busy environments such as tolls and public transportation.
