The Zebra MC3330R is a handheld UHF RFID reader built into a pistol-grip "gun" form factor, designed for inventory counting, asset tracking and retail/warehouse stocktaking where reading many RFID tags quickly from a distance matters more than a standard barcode scan. It combines a circular UHF RFID antenna for tag reading with a Zebra SE4750SR 2D imager (with LED aimer) for standard 1D/2D barcode scanning on the same device, so one unit covers both RFID and barcode workflows. It connects over 802.11 a/b/g/n/ac Wi-Fi, has a 29-key keypad for data entry, ships with 2 batteries (for hot-swapping through a shift), 4GB of RAM, and runs Zebra's GMS (Google Mobile Services)-enabled Android platform.
