Changing Perceptions of RFID
reality sets in. Companies find that it's more complex than they were initially led to believe. The technology falls into the "trough of disillusionment" or the "chasm." In the case of RFID, tag manufacturers developed passive ultrahigh-frequency (UHF) tags that can work on metal and around water, and that can be read more consistently, regardless of orientation, and at longer distances. Active RFID solution providers increased the location accuracy of their products and made performance more reliable.
