TL;DR
In 2026, the SUNMI K2 self-order kiosk is a 23.8″ floor-standing or wall-mounted Android 13 terminal that restaurants across the US and Canada use for counter-side ordering, contactless SoftPOS payment, and 250 mm/s receipt printing. Rosper, SUNMI’s authorized North American distributor, ships every K2 from 8 in-region warehouses in 2-7 business days and bundles a 3-year SUNMI warranty plus free MDM with each order.

What Is the SUNMI K2 Self-Order Kiosk?
The SUNMI K2 is a self-service kiosk used by more than 300 companies across 30+ countries, according to SUNMI’s official K2 product page. In a restaurant context, the K2 sits at the entrance, counter, or queue line and lets guests browse menus, build orders, apply loyalty codes, and pay – all without occupying a staff register.
It runs SUNMI OS based on Android 13 (Config 1, the current flagship K2), which means any modern restaurant POS application, kitchen display integration, or QR-payment workflow that runs on Android will run on K2. The kiosk also ships with Rosper’s free MDM (Mobile Device Management) so multi-location operators can push menu updates, lock the device to kiosk mode, and monitor uptime remotely.
For operators evaluating self-order hardware in 2026, the K2 sits in the “all-in-one” category: a single SKU includes the touchscreen, printer, NFC reader, camera (optional), and floor stand or wall mount, removing the need to source these components separately.

Where the SUNMI K2 Fits in a Restaurant
The K2’s four configurable versions map cleanly to common restaurant footprints:
Quick-service restaurants (QSR) and fast casual
QSR operators use the K2 Restaurant version near the entrance or order line to capture customers who would otherwise wait at the counter. A typical 2-kiosk QSR install replaces 0.5-1.0 cashier shifts per location while increasing average ticket through upsell prompts. Throughput depends on menu complexity, but Android-based self-order kiosks in QSR commonly process 40-80 orders per hour per kiosk during peak.
Coffee and bakery
Coffee shops and bakeries deploy K2 in wall-mounted form (16.5 kg) at the front counter, where the small footprint matters. The Restaurant version’s contactless loyalty card reader and QR scanner mean guests can redeem a rewards code and pay in one flow.
Full-service and casual dining
For full-service restaurants with reservations or pay-at-table, the K2 typically lives at the host station for check-in, party-size capture, and waitlist sign-up, while servers handle in-meal ordering on a SUNMI handheld like the V3 family or Flex 3.
Ghost kitchens and pickup counters
Operators running ghost-kitchen brands use the K2 as a pickup confirmation and tip-prompt terminal. The NFC + SoftPOS combination means tipping and split payment work even without a separate payment device.
Pricing for SUNMI K2 in North America: What Restaurants Pay
Pricing for the SUNMI K2 self-order kiosk varies by configuration (Retail / Restaurant / Healthcare / Extendable), mounting (floor stand vs. wall mount), and order quantity. Rosper does not publish unit pricing on a public page because most K2 buyers in North America request a tailored quote – restaurants typically need a 3-10 unit pilot, multi-location rollouts size up to 50-500 units, and ISV partners ask for OEM pricing tiers.
What we can share publicly about how K2 pricing works through Rosper:
- List price baseline is set by SUNMI; Rosper applies North American landed-cost adjustments (no overseas import fees passed to you).
- Volume tiers kick in at recognizable break points – single units, small fleets (10-25), mid-fleet rollouts (50-100), and enterprise (100+).
- Floor stand vs. wall mount is a meaningful cost delta because the floor-standing K2 (45 kg) and floor-standing with tray table (58 kg) include the stand and base hardware.
- Free MDM is included with every Rosper purchase – there is no per-device management fee added to your TCO.
- 3-year SUNMI warranty is bundled, not an extra line item – this is standard on Gen 2 / Gen 3 SUNMI devices through Rosper.
To get K2 pricing for your specific configuration and quantity, request a quote from Rosper with your location count and use case.
Sample Process for K2 in the US and Canada
Most restaurant operators and ISV partners want to test the K2 with their software stack before placing a fleet order. Rosper’s sample process is built for that:
- Submit a sample request on the Rosper contact page with your business name, country (US or Canada), and the K2 version you want to evaluate.
- Stock check and warehouse routing – Rosper confirms which of its 8 North American warehouses has the closest unit, which sets the shipping ETA.
- Sample unit ships in 2-7 business days to your address. In-stock K2 units typically dispatch within 2 business days; if your configuration is on backorder, Rosper communicates the lead time upfront.
- Software integration support – once the sample arrives, Rosper’s solutions team helps you confirm your POS software runs in kiosk mode, MDM is provisioned, and payment integration works against your test merchant account.
- Fleet quote follow-up – after a successful pilot, your sales contact moves you to a multi-unit quote with volume pricing and a deployment timeline.
Canadian restaurants follow the same flow – Rosper ships to both the United States and Canada from its 8-warehouse network, so there is no separate cross-border import process for buyers in Toronto, Vancouver, Montreal, or Calgary.
Payment, POS Software, and Printer Integration
The K2 is intentionally agnostic about the rest of your stack. A few practical notes:
Payment processors
The K2’s NFC reader is standard, and the kiosk supports SoftPOS contactless payments out of the box. For card-present payments (chip + PIN, swipe, EMV), most North American restaurants pair the K2 with a SUNMI P3 family terminal mounted in a side bracket. SUNMI’s payment SDK supports common North American processors including TSYS, Fiserv, Worldpay, Global Payments, and Moneris (Canada) – your processor relationship determines which path you certify on.
POS software
The K2 runs Android, so any Android-compatible restaurant POS or self-order application installs and runs in kiosk mode. Rosper does not require you to use a specific software vendor; operators bring their own POS stack, and Rosper’s solutions team helps validate that kiosk-mode lockdown, MDM, and printer integration work end-to-end before you scale.
Printer and peripherals
The 80-column thermal printer with Seiko engine handles 58 mm or 80 mm receipt paper and prints at up to 250 mm/s. Receipt formatting is controlled by your POS application using SUNMI’s standard print SDK. Optional peripherals – barcode scanner module, PSAM card slot, and 3D facial recognition camera – are added at the configuration stage.
SUNMI K2 Warranty and Support in North America
Every K2 purchased through Rosper includes SUNMI’s 3-year manufacturer warranty (Gen 2 / Gen 3 standard), as documented on the Rosper warranty page. Key points operators should know:
- 3-year hardware warranty applies to the K2 chassis, motherboard, display, and core electronics.
- 1-year wear-parts warranty covers the printer assembly, batteries, chargers, and other consumable components.
- Free DOA replacement is provided for units that are dead on arrival within 90 days of manufacture and 15 days of activation.
- Rosper coordinates RMAs directly with SUNMI – you submit a ticket on the SUNMI warranty portal, and Rosper handles the back-and-forth so you stay focused on the restaurant.
- Emergency device replacement is available from Rosper’s in-stock inventory when downtime is unacceptable; a swap unit ships from one of the 8 warehouses while the warranty ticket is processed.
For multi-location chains, Rosper also offers centralized warranty coordination – a single point of contact for all K2 (and other SUNMI device) RMAs across your fleet.
How K2 Compares to the K2 Mini
Operators often ask whether to choose K2 or K2 Mini. The short answer:
- K2 = 23.8″ floor-standing or wall-mounted; designed for queue-line, high-volume QSR, or wall installations where the larger screen drives upsell.
- K2 Mini = countertop form factor with a smaller display; designed for tight counters, coffee shops with limited footprint, and back-bar pickup confirmation.
Both run the same SUNMI OS, both support NFC + SoftPOS, and both work with the same MDM and POS software stack – so the choice is primarily about physical space and customer flow.
