SUNMI M3: Built for Restaurants and Food Service
The SUNMI M3 is purpose-designed for front-of-house operations. It’s lighter, more focused, and strips away features that food service teams simply don’t need.
Why Restaurants Love the M3
Effortless NFC payments right on screen. The M3 supports SoftPOS payments with EMVCo PCD L1 certification, which means customers can tap their card or phone directly on the screen to pay. No external payment dongle required. For tableside checkout at a busy bistro in Vancouver or curbside pickup at a quick-service restaurant in Miami, this matters.
The NFC module supports ISO/IEC 14443 Type A/B, Mifare, Felica, and ISO 15693, so it works with virtually every contactless card and NFC tag on the market.
IP65 protection handles real kitchen conditions. Between cooking fumes, flour dust, spilled soup, and the occasional soda splash, restaurant handhelds take a beating. The M3’s IP65 rating seals out dust and water, and the Corning Gorilla Glass screen shrugs off scratches from keys and utensils. The magnesium-aluminum alloy body with reinforced corners survives drops from up to 1.5 meters onto concrete.
Four carry options for every shift. Hand strap for order-taking, wrist strap for quick transactions, shoulder strap for managers on the move, and a lanyard for event staff. The M3 weighs just 272g, so it’s comfortable to carry through a full shift.
SUNMI Hyper Wi-Fi keeps orders flowing. Wi-Fi coverage is the Achilles heel of most restaurant handhelds. The M3’s optional Hyper Wi-Fi (802.11ah) pushes range over 10x farther than standard Wi-Fi, automatically switching between Hyper Wi-Fi and traditional 5GHz/2.4GHz bands. That means fewer dead zones between the dining room and the kitchen.
400,000+ Antutu score. The octa-core 2.2 GHz processor with UFS storage delivers 8x the performance of the previous generation. Rapid multi-application switching in SUNMI OS 4.0 means no lag between the ordering app, payment screen, and inventory check, even during peak hours.

SUNMI L3: The All-in-One Workhorse for Retail and Logistics
The SUNMI L3 takes the same core platform and adds serious enterprise capabilities. It’s the device you hand to a warehouse worker, a retail stock clerk, or a delivery driver and know it’ll handle whatever the shift throws at it.
What Sets the L3 Apart
Built-in professional barcode scanner. This is the single biggest differentiator. The L3 integrates an industrial-grade scan engine that reads both 1D and 2D barcodes, including damaged, faded, or distorted codes. It also handles bulk recognition of multiple barcodes simultaneously. For shelf stocking, order picking, and delivery verification, this eliminates the need for a separate scanner gun. The optional trigger handle (available April 2026) adds a pistol-grip for comfortable scanning during long shifts.
Dual-sided NFC readers. The L3 has NFC on both the screen and the back of the device. Screen NFC handles SoftPOS payments and membership card reading, just like the M3. But the back NFC adds electronic access control and patrol check-in capabilities. A retail manager can unlock a stockroom door and accept a customer payment on the same device.
Optional built-in RFID module. For high-volume retail and warehouse operations, the L3 offers a UHF RFID reader operating at 902-928MHz (US) or 865-868MHz (Canada/EU). Key RFID specs:
- Output power: 5 to 33 dB
- Max read range: 4 meters
- Fastest read rate: 300 tags per second
- Extended range: Recognize items from 4 meters away, reading entire shelves in one go
- Bulk reading: Read over 300 tags simultaneously with a single device
IP68 protection and 2000-drop tumble testing. The L3 doesn’t just resist dust and water splashes. It survives full immersion in 1.2 meters of water for 30 minutes, and has been tested through 2000 consecutive drops from 0.5 meters. It’s the device you give to teams working in freezers, loading docks, and outdoor yards.
4G cellular connectivity with eSIM. Unlike the M3, the L3 supports 4G/3G/2G cellular data, with an optional eSIM for flexible carrier management. This is critical for delivery drivers, field sales teams, or any operation where Wi-Fi isn’t guaranteed. A logistics company tracking shipments across a distribution center in Ontario or a field service team covering multiple sites in Texas can stay connected everywhere.
Hot-swap battery for 24/7 operations. The L3 offers an optional hot-swap battery system, so workers can swap in a fresh battery without shutting down the device. The intelligent battery algorithm automatically switches between Long Life and Long Runtime modes. For round-the-clock operations, this means zero downtime during shift changes.
Fingerprint login for security. The power button integrates a fingerprint sensor for fast device and app access, with multi-user support and tiered access controls. This is essential for shared devices in retail and warehouse environments.
L3 Use Cases in Detail
- Retail: Receipt verification, stocktaking, membership lookup, shopping guide assistance, and checkout, all from a single device
- Supermarkets: Shelf stocking with route planning, order picking, real-time inventory checks, and delivery navigation
- Supply chain: Raw material management, production tracking, inbound and outbound inventory verification, and transportation management
