Born and established itself as a technology for the logistics and then for reading long-range, in recent years, the UHF frequency is tentatively application but also in the field Near Field (the first experiments date back to mid 2009) but with an immediate and obvious advantage over technology LF and HF which is to be able to manage a large number of tags simultaneously.

R4I is specialized over the years in RFID technology and in particular in the UHF RFID technology, its declination in the near field.

The company is focused on solving specific problems arising from the use of this frequency for the close reading which enabled a job winning under near field, a field for which technology had not even been hypothesized. The core technology of the company consists in the design of methods, algorithms and dedicated hardware, for the management of objects tagged close together and at low distance from sitema reading RFID; objects then, all equipped with a RFID transponder operating in UHF frequency.
