The Zebra MC3330XR is a pistol-grip handheld UHF RFID reader built for warehouse, retail and logistics teams tracking tagged inventory and assets at range rather than scanning barcodes one at a time. This configuration uses a circular antenna for a wide, forgiving read pattern across variably-oriented tags, combined with an SE4770 2D imager for standard barcode scanning on the same unit. It has a compact 38-key keypad, 802.11 a/b/g/n/ac Wi-Fi, an extended-capacity battery for full-shift use, 4GB of RAM and Google Mobile Services. Businesses running mixed RFID-and-barcode warehouse or retail-backroom operations choose this device to avoid carrying two separate scanners.
