Design of UHF-based RFID Systems

One key factor when it comes to designing solutions using passive UHF RFID is to understand how exactly the technology works, with its benefits and limitations, and to ensure that products are designed to address business needs successfully to provide a return on investment (ROI). Basic components of any UHF RFID solution could encompass the following segments: readers, antennas, general-purpose input/output (GPIO) devices, power sources, middleware to process tag data, software, handheld readers, printers and tags. Usually, depending on the application being developed to serve a business need, any or all of these hardware components could be used, in addition to other hardware infrastructure available on the market. But before we start designing a solution, the first question to ask is what business need we are trying to solve with the application.
