Your busiest lanes can’t afford hesitation
High-volume lanes operate under nonstop pressure. Large baskets, back-to-back transactions, and constant scanning leave no room for delay or inconsistency. When a lane slows down, lines build immediately and throughput suffers.
Mach Flex is designed to remove that risk by delivering sustained performance in environments where checkout never pauses. From scanning and pricing to payments and receipts, every interaction is optimized for continuous, high-throughput lane operation.

Mach Flex is built to remove friction from high-volume lanes, so your team can focus on moving customers through checkout instead of managing system slowdowns.
This is a lane POS designed to keep pace with nonstop retail traffic.
Mach Flex is engineered for sustained demand. Scanning, pricing, payments, and receipts remain responsive transaction after transaction, helping your busiest lanes maintain consistent speed throughout the day.
High volume does not mean sacrificing reliability.
Every transaction runs through the SuperSonic POS platform, keeping pricing rules, tax settings, and inventory synchronized automatically across all lanes.
As volume increases, accuracy stays intact.
Mach Flex integrates directly with the peripherals your high-volume lanes depend on, including scanners, receipt printers, cash drawers, and payment devices.
Everything operates through SuperSonic POS, eliminating patchwork setups and reducing unexpected failures in your most critical checkout areas.

Your team does not need to relearn processes, and your data remains connected as you scale.
Your POS connects to the rest of your business
