RFID

Since 2010, after a long period of tests and pilot projects, we at l&tc have been using the RFID technology in our warehouses. The perfect interconnection between tags, antenna, and software allows us to reduce goods processing times significantly, as well as to simplify the management of the logistics chain without underestimating all the benefits with regards to the security margins.

RFID stands for radio frequency identification and refers to a set of systems that can identify objects automatically.

Think of RFID as a barcode that can exchange information via radio waves and update itself over time.

This is possible thanks to the antenna that reads a digital chip (called tag or transponder) applied to the object. The tag contains a certain amount of information concerning the object it is applied to (code, production date, manufacturer), which can be static or change over time.

The tag works through magnetic induction and does not require power. When it’s “lit” by the magnetic field of the antenna, it accumulates the energy needed for the short-range transmission of the information it contains. This type of tag is known as a passive tag.
If more power is required for transmission over a longer range, the tag needs to be supplied by a power source, such as a battery. In this case, we have an active tag.

Today, RFID is an essential tool for any supply chain professional because, in addition to other technologies, it allows for extraordinary control over packages and single products, thereby speeding up procedures and increasing the level of security.

This is why we at l&tc have immediately believed in the potential of this technology. In fact, we were the first in Italy to experiment it in this sector.

The advantages of RFID compared to an ordinary barcode are exponential!

The readout does not require direct contact and line of sight; therefore, there is no need to face the tag towards the antenna.

Tags can even be read simultaneously. Moreover, they can resist harsh environmental conditions (thermal, chemical, and mechanical stress). All this makes them more durable and reliable than a barcode.

Tags contain much more information than barcodes and, whenever necessary, they can be rewritten and updated with new information.

Barcodes identify only the product batch, but not the single item. RFID tags, on the other hand, contain a unique series number which identifies every single product in the world without any chance for error.
