FROM CUSTOMER TO COUNTER
One Device Across More Service Points
The HM638 helps teams serve customers wherever demand builds — on the floor, at the queue, or from a fixed service point. One device can cover multiple parts of the day without changing systems.
DESIGNED FOR CONTINUOUS COMMERCIAL USE
Built Around the Demands of a Commercial Shift
The HM638 is designed for commercial environments where devices move between people, service points and counter setups throughout the day. With an integrated battery, docking options and practical hardware features, it supports both mobile service and fixed POS use.
