Method for tracking sanitary materials and goods with RFID identification system; containment area and/or structure actuating said method

A method for tracking sanitary materials and goods with an RFId identification system;

• said sanitary materials and goods provided with at least one label containing a microchip containing data of the material or good and an antenna;
• said sanitary materials and goods placeable in an area arranged for storage;
• said area being provided with a plurality (P) of transceiving radio frequency identification antennae and associated connectivity devices;
• said plurality (P) of transceiving radio frequency identification antennae and connectivity devices placed in a manner so as to receive and exchange information by means of RFId technology inside the area, so as to automatically record and detect the loading and/or collecting of the labeled materials and goods and exchange information relative to the identified objects, the method comprising:
• generating a variably radio frequency field (UHF) inside said area, said variably radio frequency field (UHF) being variable in both pointing direction and polarization of the electric field, wherein said plurality (P) of transceiving radio frequency identification antennae are dynamic transceiver antennae, such that each of said plurality (P) of transceiving radio frequency identification antennae has a radiation diagram with plural pointing directions, each pointing direction being enriched by different polarizations of the electric field;
• while generating the variably radio frequency field (UHF), carrying out the exchange of microchip-antenna information in a range of radio frequencies comprised between 850 and 960 MHz (UHF);
• and
• restricting the range of radio frequencies (UHF) by shielding the area arranged for storage of the materials and goods,
• wherein said exchange of microchip-antenna information occurs by not turning on, at the same time, the plurality (P) of transceiving radio frequency identification antennae arranged in the area,
• wherein the radio frequency field (UHF) varies inside said area and the exchange of information in the radio frequency field (UHF) occurs:
• a. by creating, for each of the plurality (P) of transceiving radio frequency identification antennae turned on and arranged in the area, a series (M) of geometric configurations of the field, by means of a series of the pointing directions that are different from each other, and
• b. by creating, for each of the geometric configurations of the field, a series (N) of different polarizations of the electric field, and
• wherein combinations of the geometric configurations and different polarizations (M×N), after the variation of the direction of the field and the polarity, are cyclically repeated over a period of time (T) during which not all of the plurality (P) of transceiving radio frequency identification antennae are simultaneously turned on.
