SUNMI K2 Retail Wall-Mounted Kiosk – Space-Saving Self-Service for Small Stores & Convenience Shops

For small retail spaces—like convenience stores, neighborhood pharmacies, or compact bookstores—every square foot counts. A bulky floor-standing kiosk can crowd your layout, making it hard for customers to move freely. That’s where the SUNMI K2 Retail Wall-Mounted Kiosk comes in: it delivers all the power of SUNMI’s self-service technology, but in a sleek, space-saving design that mounts directly to your wall. Perfect for brands like Neptune Star (pharmacies) and local BOOKSTORE locations, this kiosk lets you offer self-checkout, contactless payments, and more—without sacrificing valuable floor space.

Let’s start with its most obvious advantage: size and weight. At just 394×171×1017mm and 16.5Kg, the wall-mounted K2 is easy to install (even in tight spots) and doesn’t block walkways, shelves, or checkout counters. It’s a game-changer for stores where space is at a premium—you can mount it near the entrance for quick self-checkout, by the pharmacy counter for prescription pickups, or next to book displays for impulse purchases. Despite its compact size, it doesn’t skimp on features. The 23.8” FHD capacitive touchscreen is the same high-quality display found in the floor-standing model, offering vibrant visuals and smooth 10-point multi-touch interactions. Whether customers are scanning a barcode, entering a loyalty number, or confirming a payment, the screen responds instantly—even with wet fingers or gloves.
Under the hood, the K2 Wall-Mounted Kiosk is just as powerful as its floor-standing counterpart. Config 1’s Kyro-670 Qualcomm octa-core processor (up to 2.7GHz) and 6GB RAM ensure it runs smoothly, even when handling multiple transactions back-to-back. The 128GB ROM provides plenty of storage for your POS software, transaction logs, and promotional materials (like digital flyers for pharmacy discounts or new book releases). For stores with simpler needs, Config 2 (4GB RAM + 32GB ROM) or Config 3 (4GB RAM + 16GB ROM) offer cost-effective options that still deliver reliable performance.

When it comes to functionality, this kiosk checks all the boxes for small retail. The integrated scan engine supports 1D/2D printed and mobile barcodes—ideal for scanning snack packages, prescription labels, or book ISBNs. The scanner is positioned for easy access, so customers don’t have to stretch or contort their hands to scan items. For payments, the built-in NFC support for SoftPOS lets customers tap their phones, cards, or wearables to pay in seconds. It’s a secure solution (encrypted transactions) that eliminates the need for a separate POS terminal—saving you money and reducing clutter. If you need to accept physical card payments, simply pair the kiosk with a SUNMI P series terminal; customizable holders keep the terminal within easy reach without looking messy.

Optional 3D facial recognition adds a layer of convenience for repeat customers. The camera’s 67.9° viewing angle works for users between 1.5m and 1.9m tall, so everyone can use it comfortably. Customers can link their loyalty accounts to their face, making it easy to earn points or redeem discounts without fumbling for a card. Two 3W stereo speakers provide clear audio prompts (“Please scan your item” or “Payment successful”), guiding users through each step—perfect for customers who are new to self-service.
Printing is fast and reliable, thanks to the Japanese Seiko 80mm thermal printer. It prints receipts at 250mm/s, so customers don’t wait around, and the auto-cutter ensures clean, professional results. An optional 58mm paper roll is available if you prefer smaller receipts, and the printer’s durable design means it can handle daily use in busy stores.

Connectivity is another strong suit. Config 1 supports 2.4GHz/5GHz/6GHz dual-band Wi-Fi (IEEE 802.11 a/b/g/n/ac/ax), ensuring a stable connection even in areas with heavy Wi-Fi traffic (like shopping malls). Config 2/3 offer 2.4GHz/5GHz Wi-Fi, which is more than sufficient for most small-store environments. The kiosk also includes a 100/1000M self-adaptive LAN port for wired connections—great if you want to prioritize speed and reliability for transaction data.

The K2 Wall-Mounted Kiosk is built to last. It operates in temperatures from 0°C to 40°C, so it can handle the heat of a convenience store near a coffee machine or the cool of a pharmacy’s refrigerated section. Its white, slim design blends with most store decor, and the 7-color indicator light lets you quickly check the kiosk’s status (ready, processing, error) from across the store.

For small retailers looking to compete with larger chains, the SUNMI K2 Retail Wall-Mounted Kiosk is a must-have. It lets you offer the same seamless self-service experience as big-box stores, but in a design that fits your space. With over 300 companies in 30+ countries trusting SUNMI, you can be confident that this kiosk will help you reduce labor costs, shorten wait times, and keep your customers coming back.
