New 16 antenna port UHF Gen2 RFID Reader is battery powered with integrated GPRS cellular radio and enables management of centralized item-level inventory information of the user’s supply chain. …
… “The new device features sixteen antenna ports all capable of reading RFID tags from any antenna. The device includes digital signal processing technology, enabling improved performance in read ratios and sensitivity and supports dense reader mode.
The reader sends RFID data thru the built-in GPRS cellular radio (with SIM card) to a hosted web based Business Intelligence (BI) software platform. Now, users can run analytics and reporting as part of the total solution.
Most importantly, since this device communicates via cellular technology to ZoomaDog’s hosted web portal, the system doesn’t require any IT network infrastructure, installation or IT support to setup or maintain.
Deployment is further simplified by the device being battery powered; the reader can operate almost anywhere without concern for using or installing an electrical outlet. “ …
