RFID – Radio Frequency Identification – is a technology used to identify and trace objects, goods and people without the need for any physical contact or optical reading.

Owing to its specific characteristics, it guarantees greater control, safety and accuracy when handling data. K.F.I. possesses a team of specialists capable of verifying the potential and limitations of application of this technology, through a careful analysis of a customer’s traceability processes and of the expected return on the investment in question.

RFID employs special labels – “tags” – that communicate via radio with readers. There are two types of tag: active tags and passive tags:

Active tags
fitted with a battery, transmit the signal independently: these are suitable when there is a need to read/write at a distance of up to 15 metres.

Passive tags
are cheaper, with no battery, but fitted with a microchip, an aerial and a condenser. When prompted by an electromagnetic field, they enable information to be transmitted and received at a distance of between 25 and 120 cm.

RFID technology is ideal in extreme environments where the label may easily be ripped, or in difficult situations characterised by extremely low or high temperatures. It is particularly well suited for use in hospitals, public administrative offices, libraries, schools, civil defence units, the army, etc.
