Lanes that measure themselves in scans.
The lane is a throughput problem with a human in it: busy hours compress everything into a few aggressive seconds per customer. The U20 earns the performance label by making retries rare — the printed EAN, the laminate promo sticker on the basket, and the customer's app coupon decode on the first trigger, at the exact rhythm of a real register:
- First-trigger discipline — fewer failed reads means fewer seconds at the same customer, and at a supermarket the meter that matters is customers per hour, not scans per minute.
- Coupons without the extra step — the app promo the customer is already holding decodes at counter distance, so "let me try your phone again" disappears from the script.
- Fleet uniformity — the free SDK gives you one config across the front lane, the back office and the returns desk, and 48h FAE support keeps a 40-store rollout from drifting.
U20 FAQs
Tier and margin: U20 is the performance-family position, with a tuned trigger profile for rapid successive scans — the practical difference shows in the peak hour, not in the catalog.
Yes — counter-distance phone capture is in scope; the bagging-area read of printed codes is covered too, which is the odd angle most registers struggle with.
The free SDK includes a configuration profile; the 48h FAE line rolls it out to every store and verifies one unit per region before the rest are shipped.
