Getting the Most From Mobile RFID With Middleware

Mobile RFID enables unique RFID use-cases not possible with fixed readers. Mobile data collection devices such as scanners tethered to mobile computers, integrated handheld readers, and vehicle-mounted readers from companies such as Psion Teklogix, Intermec, LXE, and Motorola, allow the reader to be brought to the asset instead of the asset having to pass by the reader. These devices and custom applications running on them can leverage existing wireless networks to communicate continuously with the rest of the system, and can often be used offline to collect data for transmission to the rest of the system at later time. Early RFID deployments brought to light a number of limitations with the use of fixed RFID readers for certain processes.
