UHF RFID (Ultra High Frequency = Ultra High Frequency), tags are in the range of 400 MHz to 1 GB. It is a technology used mainly for remote monitoring. It provides the ability to write as well as read chips. For example, if a ticket holder passes through a turnstile, an RFID antenna can transmit special access instructions to the ticket or card for the event in which they participated on that occasion. UHF RFID tags are widely used in industry due to their long reading distance.
