Two screens. One transaction. Better experience.
Shift4 Duo is the dual-screen countertop POS — a primary display for your staff and a customer-facing screen for the guest. Order confirmation, tip selection, signature capture, and digital receipts all happen in plain sight.
Better tips. Cleaner transactions. Trust built into the counter.
The customer sees what they're paying for.
Order details, modifiers, and totals displayed on the customer-facing screen as they're entered. Builds trust, reduces "wait, that's not what I ordered" moments at the register, and speeds up the line.
Tip selection without awkwardness.
Tip prompts on the customer screen — not flipped around for the guest to squint at on the staff terminal. Industry data consistently shows on-screen tip selection lifts average tip percentages.
Receipts the modern way.
Email receipts, text receipts, or print — selected by the guest on their own screen. Builds your customer database for marketing, reduces paper waste, and feels like the business is ahead of the curve.
A complete two-screen counter station, ready to deploy.
Primary touchscreen
High-resolution touchscreen for staff order entry — same software experience as Shift4 One, with full Shift4 Dine capability. Bright, responsive, and calibrated for fast keystrokes during peak.
Customer-facing screen
Secondary touchscreen positioned for the guest. Displays order details, totals, tip selection, signature capture, and digital receipt options. Customizable with your branding when idle.
Tap, dip, or swipe at the counter
EMV chip, contactless tap, magnetic stripe, and mobile wallets — all on the customer-facing screen. Tip selection, signature, and receipt choice happen on the guest's side, in their hands.
Idle screen advertising
When the customer screen isn't running a transaction, display promotions, daily specials, loyalty signups, or branded content. Counter real estate that earns its keep even between transactions.
Restaurant-grade build
Spill-resistant chassis on both screens, sealed ports, reinforced touchscreens. The customer screen rotates and tilts for ADA accessibility and varying counter heights.
Full Shift4 Dine
Same software as every other Shift4 station — front-of-house, kitchen routing, reporting, integrations. The customer-facing experience is built into the platform, not bolted on.
Built for counters where the customer experience is the product.
Quick-Service Counters
Customer sees their order as it's entered, confirms it, and runs payment without anyone reading totals upside down. Speeds the line, reduces order errors, and lifts average tips.
Coffee & Cafes
Morning rush counters where speed and tip capture both matter. Customer screen handles the "$1, $2, custom" tip selection — research shows this lifts tip averages by meaningful percentages.
Bakeries & Specialty Retail
Customer-facing screen builds trust for itemized orders — six pastries, two coffees, a gift card, a loyalty redemption. Guest sees the math as it's entered, not as a surprise total.
Fast-Casual Build-Your-Own
Bowls, burritos, salads — orders with lots of customization. Customer screen confirms each modifier as the staff enters it. Fewer remakes, happier guests, faster line.
Tip-Forward Concepts
If your concept relies on counter staff tips — counter-service restaurants, ice cream shops, juice bars — Duo's customer-facing tip prompt is one of the highest-ROI hardware decisions you can make.
Brand-Forward Operators
When the customer screen is idle, it becomes a branded surface — promotions, loyalty signups, social handles, product photography. Counter advertising that earns its keep between transactions.
