Linqu (Henan Linqu Intelligent Technology Co., Ltd.) is a professional smart locker manufacturer and integrated solution provider based in Zhengzhou, Henan, China. Founded in 2018, Linqu designs, manufactures, and delivers smart locker systems worldwide — smart parcel lockers, self-service pickup lockers, smart storage and luggage lockers, smart laundry lockers, vending lockers, phone charging lockers, and fully customized electronic locker solutions. From cabinet structure and electromagnetic locks to control boards, Android terminals, cloud platform, and user interface, every component is developed in-house and can be tailored to your operation, brand, and region.
A Real Factory, Not a Trading Company
Linqu's 20,000 sqm smart locker research and production base in Luoyang, Henan, China.
Linqu operates a 20,000 sqm research and production facility. Sheet-metal fabrication, powder coating, electronic assembly, and software development all happen under one roof. For buyers, this vertical integration means three concrete things:
Factory-direct pricing — no middleman markup between you and the production line.
Every component is customizable — cabinet dimensions, compartment mix, colors, logo, UI screens, and business workflows.
One team owns hardware and software — compatibility, commissioning time, and after-sales responsibility sit with a single supplier, not three.
Linqu smart lockers are deployed in residential communities, commercial complexes, transport hubs, campuses, public facilities, and tourist attractions across the globe.

Six Product Lines Covering Every Mainstream Locker Business
1. Smart Parcel Lockers
Parcel drop-off, identity verification, automatic notification, and remote management in one terminal — built for last-mile delivery. Couriers scan to deposit; the system assigns a compartment and sends a pickup code; recipients collect 24/7 by PIN, QR code, or app. Ideal for residential communities, apartments, offices, campuses, and logistics stations. Explore our smart parcel locker range.
2. Self-Service Pickup Lockers
Staff deposit orders; customers collect with a one-time code — so your store keeps handing over orders after closing time. Widely used for BOPIS (buy online, pick up in store), pharmacies, repair shops, and dry cleaners. See the self-service pickup locker line.
3. Smart Storage & Luggage Lockers
PIN, QR, face, fingerprint, or RFID access with time-based billing or free-then-paid modes. A proven paid-storage business for tourist attractions, airports, railway stations, and shopping malls. Browse storage and luggage lockers.
4. Smart Laundry Lockers
An unattended drop-off and pickup terminal for laundry, shoe cleaning, and dry cleaning: customers deposit and order, the service provider collects, cleans, and returns items to the locker — fully tracked and paid online. Laundry brands use it to expand into apartments, campuses, and hotels with minimal staffing. See laundry and shoe cleaning lockers.
5. Smart Vending Lockers
One compartment, one product: pay by QR code or POS card, and the door opens. The back office manages products, inventory, and revenue in real time — ideal for unattended retail, hotel amenities, and campus convenience. Explore vending and food lockers.
6. Phone Charging Lockers
Charge and store securely at the same time, with fingerprint, face, or PIN access. Deployed in schools for phone management, plus events, airports, and malls — with optional advertising screens for extra revenue. See phone charging lockers.
One Software Platform Behind Every Locker
Every Linqu locker runs on the same self-developed cloud system — the biggest difference between Linqu and factories that only sell steel cabinets.
For operators: a web-based cloud back office
Unified multi-locker management with real-time compartment monitoring;
Order, revenue, and utilization statistics with data export to support operating decisions;
Role-based permissions and audited operation logs;
Cloud-hosted with no local server, with remote upgrades and remote troubleshooting.
For end users: a localized experience
Multilingual interfaces (English, Arabic, French, and more — any language can be added);
Local currency display and local time formats;
Automatic pickup-code notifications by SMS or app, with real-time order status alerts.
For developers: open integration
Standard APIs: order management, compartment control, payment callback, and status query;
Integrations with ERP / CRM, your own app or mini-program, and third-party logistics or store systems;
Modules enabled on demand — one system extends to laundry, vending, document workflows, and more.
OEM / ODM: From White-Label Lockers to Core Components
Linqu core control kit: Android touchscreen, lock control board, and electromagnetic locks.
Many partners don't just want to buy lockers — they want to build their own smart locker brand and network. Linqu supports every route:
Route 1: Complete-locker OEM / ODM
Cabinet dimensions, compartment mix, colors, logo printing or film, boot screen, and UI are all built to your brand. Business workflows — approval steps, special pickup flows — can be custom-developed. You receive a locker that is entirely yours.
Route 2: Core control components
For cabinet makers, metal fabricators, and system integrators with their own production capacity, we supply the "heart" of a smart locker as a matched set:
Industrial Android touchscreens — 7", 10", or 21.5", RK3568 quad-core with Android 11, WiFi / Ethernet / 4G options, plus a wide-temperature variant rated -20°C to 70°C. See the OEM Android touchscreen terminal.
Lock control boards — 18, 24, or 32 channels, operating from -40°C to 85°C, with reverse-polarity, RS485 misconnection, lock short-circuit, lightning surge, and electrostatic protection. See the 18-channel RS485 lock control board.
Industrial electromagnetic locks — rated for 50,000 cycles (100,000-cycle option), emergency manual release, anti-rust metal housing.
Buying the set from one supplier means compatibility, commissioning time, and after-sales responsibility never fall between vendors.
Route 3: Your software + Linqu hardware
Building your own system? We provide product feature references, interface documentation, and full technical support including API and SDK, so your team can integrate quickly. Deployed customers can also purchase screens, boards, and locks as spare parts for local after-sales stock. Browse all smart locker components.
Manufacturing and Quality You Can Verify
Cabinet build: galvanized or cold-rolled steel, 0.6–1.2mm standard thickness (customizable), anti-pry design, powder-coated and rust-protected for industrial durability.
Environments: indoor, semi-outdoor, and outdoor variants with optional waterproofing, canopy, and dust/moisture protection; UPS backup and solar off-grid power options for unstable-grid sites.
Practical engineering: lift-rod handles, maintenance access doors, and knock-down (assembled) cabinet structures that cut shipping cost and speed up installation.
Compliance: complete-machine CE certification (EMC / LVD / MD) with an EU Declaration of Conformity; component-level certificates and test reports available for tenders and procurement review.
Export packaging: reinforced packaging engineered for long ocean transit to reduce arrival damage.
Global Deployments: Two Kinds of Markets, Both Proven
Linqu serves B2B customers worldwide, with deployments across East Asia, Southeast Asia, North America, and Africa — in residential, commercial, transport, campus, public, and tourism settings. Projects tend to fall into two shapes, and we have delivered both end to end.
Mature markets — deepening service experience and operating efficiency:
Hong Kong — a parcel locker network for high-density buildings, integrated with YedPay / EFT Pay so users pay by Alipay, WeChat Pay, Visa/Mastercard, or PayMe.
United States — in-store pickup lockers: staff deposit, customers collect by code, and order handover no longer stops at closing time.
Singapore & Malaysia — shoe-cleaning locker networks that boost brand trust and let care brands expand with light staffing.
Emerging markets — building infrastructure ahead of the competition:
Kenya — smart parcel lockers deeply integrated with M-Pesa (phone-number PIN and QR payment), positioning our customer early in a last-mile market still taking shape. What this proves is not that "the locker works" — it proves Linqu can complete an end-to-end adaptation around a brand-new market's payment and usage habits, from zero.
These are representative slices of different market types, not an exhaustive list. Even if your market isn't named here, you will likely find a project above that shares your deployment conditions — payment methods, power standards, climate, or operating model. That is exactly what the next section addresses.

Localization: Not a List of Supported Countries — a Method for Entering Any Country
The real barrier to deploying lockers abroad is never the cabinet. It is payment, power, language, and compliance. Linqu has built these four into standardized adaptation layers — lists end, capabilities don't:
Layer 1: Payment — three paths that cover global habits
Local mobile payment integration via standard payment callback APIs — live examples include M-Pesa in Kenya, PayNow in Singapore, YedPay / EFT Pay in Hong Kong, and aggregated multi-platform payment in Malaysia.
International cards and contactless via optional Nayax and similar POS modules for card-first markets such as Europe and North America (country coverage and rates confirmed per project).
QR / in-app / no-payment modes — QR payment, payment inside your own app, and free internal scenarios (employee lockers, document exchange) are all standard.
Layer 2: Power — one adaptation for global grids
AC 110V–240V wide-voltage support, 50Hz / 60Hz compatible.
Country-specific plugs (Type A/B, Type G, and more have shipped).
UPS backup and solar off-grid power for unstable or absent grids — a deployment condition many factories simply cannot cover.
Layer 3: Language and experience — any language can be the native interface
Built-in multilingual UI (English, Arabic, French, and more) with custom addition of any language.
Local currency display and local time/date formats.
Pickup codes and order notifications delivered by SMS or app push, following local habits.
Layer 4: Compliance — certification documents ship with the project
Complete-machine CE (EMC / LVD / MD) certification with EU Declaration of Conformity; EU Authorized Representative and German EPR supported.
Component-level certificates and test reports for screens and electronics, ready for tenders and platform audits.
For other target markets, we confirm certification requirements per project and provide the supporting documents.
Wherever your market is, tell us the country and scenario, and we will map the adaptation across all four layers — for Linqu, entering a new market is a standard procedure, not an adventure.
