Our Smart Locker and Smart Lock Development Services

Product Planning and Hardware Feasibility

We assist in defining the workflow of the lockers, users’ identities, as well as the points of connectivity and integration. In the initial phases, we will analyze the hardware manuals and run tests around the functions available from the sample devices.

Customer, Courier and Employee Mobile Apps

We develop Android and iOS applications for booking lockers, receiving collection instructions, accessing assigned compartments and managing rental sessions. Interfaces can be tailored to customers, delivery staff or employees, with each role seeing only the actions it needs.

Web-Based Locker Management Software

Give your operations team a central place to manage sites, locker banks, compartments and users. Depending on available hardware data, the dashboard can show reservations, access events, connectivity status and maintenance issues, with permissions for different administrative roles.

Kiosk and App-less Access

Some customers want to pick up the parcel without downloading an application. We create the workflow in a kiosk or browser with the methods of PIN codes, QR codes among the other methods, and we prepare the instructions on the errors with codes, failed attempts and support requests.

Lock, Controller and Gateway Integration

We connect applications with compatible manufacturer SDKs, APIs and documented device protocols. The integration may involve individual locks, a central controller or a gateway. Supported commands, event reporting and offline behaviour are confirmed for the selected hardware.

Locker Allocation and Reservation Systems

We build allocation rules around compartment size, location, availability and booking duration. The software should prevent competing bookings from receiving the same compartment and handle cancellations, expired reservations and lockers temporarily removed from service.

Parcel Delivery, Click&Collect and Return

We develop solutions for authentication of the courier, compartment assignment and messages to the customer. Return can include validation of the order and pickup by the authorized courier. Our solution helps to connect these events and your logistics and retail systems.

Rental, Subscription and Payment Integration

For luggage storage, gyms and shared facilities, we develop booking, pricing, payment and extension workflows. Payment records remain separate from physical access events, allowing staff to investigate situations where a customer has paid but a locker has not opened.

Employee Storage and Equipment Lending

We create applications for assigned workplace lockers and shared equipment such as laptops, tools and devices. Features can include employee authentication, item reservations, issue-and-return records, overdue reminders and integration with supported inventory or IT service platforms.

Digital Credentials and Access Approvals

We make use of the credential techniques your hardware allows us to operate. Typical tasks include issuing temporary credentials, setting expiration times, revoking issued credentials and limiting their usages by the clients. Permissions may be local or remote depending on the capabilities of the platform used.

Business System and Cloud Integration

Connect locker activity with your existing software through approved APIs and event integrations. Relevant systems may include order management, warehouse software, employee directories, customer support and payment providers. We also plan how failed or duplicated events should be handled.

Smart Door Lock and Cabinet Lock Applications

Alongside locker systems, we develop applications for compatible door and cabinet locks. Projects may include mobile keys, scheduled access, visitor permissions and administration tools. Each integration is scoped around the specific lock model, manufacturer platform and available developer access.

Security, Reliability and Device Testing

Testing covers more than a successful unlock. We assess permission checks, expired credentials, repeated requests, interrupted connections and application recovery. Hardware testing also checks which physical events can be confirmed and how the interface should communicate uncertainty.

Deployment, Transfer and Ongoing Maintenance

We provide assistance with the launch of trials and commercial use of the product. The transfer would include source-codes, integration documentation, step-by-step instructions on how toimplement the system and its use. The continuance might include mobile operating system improvements, changes in the vendor’s APIs and investigation of any incidents taking place.

Specialized Locker and Lock Applications

Let’s look at some examples of the sectors for which we build apps.

Parcel Delivery Locker Apps

If you’re in e-commerce or logistics, you understand the challenges of last-mile delivery. We want an app that:

  1. Makes it easy for delivery agents to drop off parcels,
  2. Instantly sends a one-time code (OTP) or QR code to the customer,
  3. Allows real-time tracking of locker availability.

We can build all of this, along with API integrations, so your entire system runs smoothly.

Rental and Shared Locker Systems (e.g., gyms, railway stations)

Here, the focus is on user experience. Customers should quickly rent a locker, make a payment, and get an access code. We’ve created apps that handle high traffic without any issues.

Smart Home and Office Lock Apps

These apps have different requirements. They need to do more than simply lock and unlock. We must:

  1. Provide temporary access e.g., giving a visitor access for one hour,
  2. Keep a complete history of who entered and left the home and when,
  3. Integrate with other smart home devices e.g., Alexa or Google Home.

Global Smart Lock & Smart Locker Brands We Have Worked With

If you're creating a new smart access solution, whether for a residential building or a large parcel network, the biggest challenge is picking the right hardware partner. You need a partner that not only makes locks but also offers a platform that your team can easily connect to your custom app.

At Adequate Infosoft, we understand that your time is valuable. That's why we compiled a list of brands that offer reliable B2B solutions and developer tools (SDK/API) This information will help you make the best first steps. We have successfully integrated their solution into our SDK app.

Let's talk about some companies that focus mainly on door and personal access control. These brands help you create the system for your building or property management app, and we are experts on these brands.

TTLock smart lock

TTLock

TTLock is more of an ecosystem than just a hardware brand. It's a workhorse in smart lock development. Many hospitality businesses, like hotels and Airbnb, as well as multi-family rentals use them. They shine because they provide a common SDK/API for nearly every type of lock, including door locks, cabinet locks, and bicycle locks.

How to Use (Integration Overview):

If you are developing an app that needs to give thousands of users temporary access codes within minutes, TTLock's SDK is essential. Your app communicates with TTLock's API, simply saying, "Give this user access to this lock from this time to that time." TTLock's cloud does the rest, speeding up app development significantly.

Tuya smart lock

Tuya Smart

Tuya doesn’t sell locks directly; instead, it operates a huge IoT cloud platform. You can think of it as a highway connecting various Internet of Things (IoT) devices. Numerous manufacturers worldwide use Tuya’s cloud to enhance their smart locks.

If you want to control not just smart locks but also smart lighting, plugs, and cameras from your app, Tuya is useful. You can connect your custom app to thousands of Tuya-compatible devices using their extensive API. This is especially beneficial for projects involving large smart homes or smart offices.

This all occurs through a highly secure cloud setup. If your main focus is communication between the phone and lock, Tapkey is a solid choice.

Bloq.it smart locker

Bloq.it

Bloq.it creates modular and customizable smart locker systems. They provide not just locks but also a complete locker operating system (Bloq.OS). Their focus is on complex logistics like parcel delivery, retail pickup, and drop-off.

Logistics companies often use these systems. Your app needs to connect with the locker network using Bloq.it’s REST APIs. For example, you might say, "I need to put a parcel in locker A2." Or you could say, "User B has taken a parcel from locker C5." They have the advantage of managing the entire network instead of just individual lockers. This makes them ideal for large e-commerce projects.

RemoteLock platform

RemoteLock

RemoteLock is an access control platform that lets you manage various hardware brands (e.g., Schlage, Yale, August) in one place and built for property managers who need to control multiple locks and lockers from a single app.

RemoteLock emphasizes cloud-to-cloud integration, so if your client already has various smart locks in place, you can connect your app to the RemoteLock API instead of integrating with each lock brand separately.

RemoteLock will manage all those separate locks, making it an excellent solution for complex property ownership.

Technology We Use

Using the right technology is essential for building a robust, fast, and secure app.

Whenever we create a smart locker or lock app, we focus on:

Bluetooth Low Energy (BLE) or NFC integration

This is the easiest and quickest way to connect the app to the lock hardware. We make sure the connection is instant, even if the user has an older phone or slower internet.

Cloud-based backend

All data, like user profiles, access codes, and log history, is securely stored in the cloud. We use Amazon Web Services or Google Cloud Platform to ensure your system can support thousands or millions of users.

Security protocols (Encryption)

This is crucial. Encrypting access codes and data transfers is a must and apply the latest encryption standards to prevent data theft.

Platforms

We create native apps for iOS and Android. If you're on a tight budget and need to launch quickly, we can use a cross-platform framework like Flutter or React Native. It all depends on what you need.

What Happens When a Locker Does Not Open?

A customer scans a collection code, but the door stays closed. What should happen next?

The application needs to distinguish between a valid credential, an accepted unlock request and a confirmed physical event. These are different outcomes.

The receiving of payment confirmation card or closed door indication does not assure that the compartment has opened or that the parcel is indeed in the compartment. If something is outside the parameters of the device, there should be indications that this factor exists.

We define these situations during planning, which includes rules about retries, escalation of support in case of the malfunctioning compartment. Also, offline access should include the specification of credentials validity, expiration and what happens with the access once connectivity is restored.

The goal is to give customers a clear next step and operators enough information to resolve the problem.

Frequently Asked Questions

Is it possible to create software customized for the lockers we have?

Through checking the lock and controller types, the SDK or API that can be utilized, the firmware and commercial access requirements. Having a working sample will help in establishing which features can be integrated.

Can customers use the lockers without downloading an app?

Yes, where the hardware supports an appropriate kiosk, PIN, QR or browser-based workflow. The right approach depends on how users are identified and how the locker receives an authorised access request.

Will the system function without an internet connection?

Certain configurations allow for local access without an internet connection using previously assigned credentials; others require constant internet connection. The use of the system offline and the limitations regarding the expiration and cancellation of credentials must be verified for the particular hardware and platform being utilized.

Can one platform manage lockers across multiple locations?

A custom platform can be designed for multiple locations, with site-specific permissions and central reporting. Capacity requirements should consider active devices, simultaneous requests and event volume—not just the number of registered users.

How much does smart locker software development cost?

The scope depends on hardware readiness, the number of user interfaces, integrations, payment requirements and operational complexity. A useful estimate separates software development from hardware, vendor subscriptions, hosting, messaging and ongoing support.

How long is the process of software development supposed to take?

As the integration prototype is different from the production lock system, the levels of work required will also differ. The schedule will depend on hardware validation and will include application development as well as integration testing and the pilot launch.

Will we own the source code?

Source-code ownership and handover should be defined in the development agreement. Third-party SDKs, vendor platforms and commercial components remain subject to their own licence terms.
