R41
The R41 is the scan-and-speak payment box of the voice payment line — a counter unit that scans the customer's QR and announces the amount out loud, which is how street retail turns a cluster of customers into a queue that trusts you.

Out loud is how the street counter stays fair.
Street retail's payment speed comes down to one moment: the customer holds up their phone QR, the counter reads it, and the amount is agreed without a spoken price check. The R41's scan-and-speak makes that moment explicit — the phone code reads and the box announces the figure, closing the loop before the customer finishes asking "how much":
- The announcement is the receipt — an amount spoken at the counter removes the silent-look disagreement that slows street queues; both sides hear the number once.
- QR from dim screens, midday sun and all — counter-facing capture plus the full 2D set handles the app mix the street retail queue actually carries.
- Box economics for the small storefront — MOQ 1 pc, 2-year warranty, and a voice set that the FAE team tunes to the local language, which is where the whole trust argument lives.

R41 FAQs
The box's voice is driven by the host's amount flow — RS232 or USB with the free SDK routine; the FAE team sets the spoken pattern (currency, digits, result) in the 48h tune-in.
It needs a host for the amount logic; a small controller or a phone POS with the SDK routine fills the role — send your counter setup and the FAE answers with a wiring plan in one working day.
The counter-facing speaker suit a normal stall's half-loudness; a fully noisy market floor needs the R45's positioning or a paired speaker — the FAE will tell you which after one field call.
