Webitem-level RFID (item-level radio frequency identification): Item-level RFID is an approach to radio frequency identification that involves tagging individual inventory units, as opposed to tagging cartons or pallets of items. WebFrequency describes the number of waves that pass a fixed place in a given amount of time. So if the time it takes for a wave to pass is is 1/2 second, the frequency is 2 per second. If it takes 1/100 of an hour, the frequency is 100 per hour. Usually frequency is measured in the hertz unit, named in honor of the 19th-century
