The Zebra MC3330XR is a pistol-grip handheld UHF RFID reader built for warehouse and logistics teams who need to read RFID-tagged stock at range rather than scan barcodes item by item. This variant uses a circular antenna for a wide, forgiving read pattern regardless of tag orientation, alongside an SE4770 2D imager for regular barcode scanning on the same unit. It has a compact 29-key keypad (suited to simpler, function-driven data entry rather than full alphanumeric typing), 802.11 a/b/g/n/ac Wi-Fi, an extended-capacity battery for full-shift use, 4GB of RAM and Google Mobile Services - a device for RFID-heavy inventory and asset-tracking operations.
