RFID tags are now part of several regular systems in life. However, there is no single solution that fits all those applications. There are several types of RFID cards that are ideal for different applications as per their characteristics. One such type is UHF tags that serve some powerful application needs. There are some applications where near proximity solutions are not viable to implement. Often some requirements rely on communication over some distance. That is where UHF tags come into play.
Introduction To UHF Tags
UHF tags are serving a different set of applications compared to classic RFID tags. Ultra-High Frequency (UHF) tags, as the name conveys, operate at a higher frequency range to transmit data within a more extended range. These tags carry a few building blocks to serve the purpose of long-range requirements. A UHF card includes an antenna and an integrated circuit as significant components, along with several memory banks. These components are ideal for supporting any data storing or power requirements for UHF tags. Here are a handful of applications where UHF tags can serve perfectly:
Tracking assets and resources can be of value in a high productivity environment. Asset tracking would allow the users to find items, resources, and even employees. As such, the range of UHF tags is perfect for such an application.
Supply Chain Management
Supply chain management is an area where a lot of parts, pieces of machinery, and teams are involved. Such a multifunctional unit can benefit from long-range communication for information exchange and coordination.
Perimeter Access Control
Access control has always been a favorite application for RFID adopters. UHF cards will enable access control from a distance. For instance, one can lock or unlock the gates with the help of perimeter access control.
Healthcare or medical care industry can have several advantages with long-range communications. For example, emergency alerts and notifications with UHF can allow immediate support to critical patients.
Travel & Hospitality Application
The travel industry has a plethora of use cases where UHF RFID can be beneficial. Long-range communication can help users keep track of their luggage. Cruise and hotels can utilize UHF RFID to identify travelers as another application of UHF RFID cards.
However, applications of UHF RFID are not limited to these areas. There are many more applications where long-range passive RFID cards will be resourceful. Being batteryless and passive, RFID can serve many applications where conventional wireless systems are not viable. At this rate, there will be many more smart city & public administrative applications of UHF RFID.
RFID has been truly reliable in its current implementations in different industries. UHF and long-range communication would allow RFID to facilitate many more applications in IoT and Industrial 4.0 domains. RAIN RFID is the passive RFID technology that allows long-range communications with devices. This adoption is growing quickly, just like any other wireless communication technology. With the growing demand for RFID for a higher range, more security and lesser cost will allow many more RFID adoptions
