UHF RFID systems for the automatic identification of RFID goods are in the phase of dynamic development. A typical system consists of a computer system with a database and two types of radio frequency identification devices. These are RFID readers, i.e. transceivers and tags. This mechanism is supported by an application that controls RFID devices.
Most commercially used RFID systems use either frequencies in the 860-960 MHz range - UHF band depending on region, or 13.56 MHz - HF band. In addition to the above-mentioned frequencies, frequencies up to 135 kHz - in the LF band and 433 MHz and 2.45 GHz - in the UHF band are also used. These are the recommendations of the European Telecommunications Standards Institute. In Poland, devices using RFID technology operating in the UHF frequency range use the 865.6 - 867.6 MHz band.
Thanks to the UHF RFID technology, the automatic identification of goods guarantees a significant improvement in the efficiency of companies from various industries, both manufacturing and service. Examples are hotels and hospitals. The use of a proprietary system of tags and readers increases security. It also prevents possible confusion, loss or falsification of marked items.
