Our KERONG Integration and Development Services

Hardware Evaluation and Proof of Concept

We perform the analysis of the lock model, controller board, power requirements and feedback signals obtained from documentation.

The proof of concept includes checking the most important performance: getting the access to the needed compartment, the release request and the response obtained. We also define those parameters that cannot be evaluated by the hardware before they become part of the application.

Locker Controller and RS485 Integration

We develop communication software for supported KERONG controllers using the documented protocol.

The work includes controller addressing, compartment mapping, command handling, response parsing and communication timeouts. RS485 describes the communication interface; the actual commands and message structure must come from the relevant controller documentation.

TCP/IP Connectivity and Gateway Development

For networked installations, we connect the locker controller to an appropriate local computer or gateway.

The gateway can coordinate hardware commands, retain necessary operational state and communicate with the backend. We establish how it behaves during network interruptions and prevent controller interfaces from being exposed directly to the public internet.

Software for Click-and-Collect and Parcel Locker

We create procedures for compartment assignment, parcel storage, notification of recipient, pickup and return.

The system separates a booking and a parcel drop-off. Moreover, it deals with problems like a compartment breaking down, a door being open, or an unsuccessful pick-up attempt.

Kiosk and Touchscreen Application Development

We build operator and customer interfaces for supported kiosk hardware.

The scope can include scanning a collection code, choosing a locker, displaying instructions and guiding the user through recovery. Session timeout, accessible instructions and protection of the kiosk’s administration functions are included in the design.

Custom Mobile Applications

We create mobile applications for end users, delivery personnel, building staff, and administration.

Mobile functionality may include locker allocation, approved release requests, local access, and operation logging. The application distinguishes between a request and a process.

NFC and Battery-Free Lock Integration

We assess supported KERONG NFC locks for cabinet, drawer and locker applications.

The work includes the authorized phone-to-lock interaction, credential lifecycle and permitted event collection. Phone compatibility, NFC behavior and the required power-transfer interaction are tested using the actual lock and target devices.

RFID, PIN, QR and Bluetooth Access Workflows

We integrate the access methods supported by the selected hardware and software interfaces.

These methods may operate at different layers. For example, a QR code may be validated by a kiosk or mobile app, which then instructs a controller to release a compartment. That does not mean the lock itself contains a QR reader.

Cloud Dashboards and Multi-Location Management

We create dashboards enabling efficient management of locations, banks, compartments, users, and operational problems.

The access rights are managed on the backend side. The local operator must only manage the assigned locations, while central operators can get broader view. Remote release and other actions subject to logging are undertaken with an audit trail.

ERP, WMS, Membership and Business-System Integration

We connect locker operations with authorized external systems.

The scope can include orders, employee assignments, equipment loans, memberships or service requests. The design establishes which system owns each record and how updates are reconciled after a failure or interruption.

Embedded Software and Custom Interface Electronics

Where standard components do not meet the agreed requirement, we can scope custom gateway firmware or interface electronics for hardware the client owns or is authorized to modify.

This may involve communication interfaces, sensor inputs, power supervision or protected output stages. Electrical limits, wiring and power behavior are validated against the selected locks and controllers.

Tracking, Assessment and Upkeep

Our monitoring practices are designed around the signals that the equipment emits, for example, communication errors, latch feedback as well as sensor data.

Testing is done to check for wrong addressing, disrupted processes, recovery, and access boundaries. Handover could involve delivering the source code as per the agreement, files with configuration information, documents on wiring, test results, and maintenance techniques.

The firmware made by the producer, equipment guarantees, and licenses granted by third parties are kept apart unless stated otherwise.

Separate the Three Hardware Approaches

Hardware Approach What the Integration Should Establish
Centrally Powered Locker Bank Controller protocol, channel mapping, power budget and feedback
Battery-Powered Cabinet Lock Credential support, available connectivity, battery reporting and recovery
Battery-Free NFC Lock Supported phone interaction, authorization, energy transfer and synchronization

Unlocking, Door Position and Compartment Occupancy Are Different States

A controller accepting a release command does not necessarily prove that the user opened the door.

Likewise, a closed door does not prove that a parcel is inside. The system needs to distinguish the command result, available lock or latch feedback, door-position sensing and compartment occupancy.

We identify the signals required before designing the dashboard. If an occupancy detection mechanism is required, it requires sensor placements and checking against what items the lock will store.

This avoids the misleading messages like “packet retrieved” when the system only knows about an unlock operation.

How Offline NFC Access and Cloud Reporting Fit Together

Local access and central reporting are separate parts of the system. Where the selected lock and credential arrangement support offline operation, a user may be able to access a cabinet without an internet connection.

That does not automatically make the event visible to an administrator at the same moment.

Integration must determine where the event has been captured, if it unlocks the event, and when the phone or other authorized device can upload it.

The dashboard must display the last sync time and the source for each record. The process for revocation must also be clearly defined; a change of the permission in the cloud does not show that an offline lock or credential has applied that change.

Custom Mobile App Development: Control in Your Pocket

What's the biggest advantage of smart locks? You can manage your access from anywhere in the world and to do this, you need a mobile app that fits your business’s needs. Generic apps often miss your specific requirements or lack the features you really need. A poor app can make the entire smart lock technology ineffective.

That's why we focus on custom mobile app development. We understand your processes, whether it’s a co-working space, a hotel, or a large warehouse. We create apps that are visually simple and easy to use but still sturdy.

For example, do you need to automatically revoke access after giving guests 24-hour access? Do you need to see who last opened the lock? Our custom app can handle all of this smoothly. The app works well on both iOS and Android platforms, ensuring a seamless user experience.

Web App Development: Management at Scale

Mobile apps are great for on-the-go control but when you need to manage hundreds of locks at once, pull reports, or control permanent access rights from one place, you need a strong web application.

A web app gives you full power as an administrator. You can view everything comfortably from your desktop on a large dashboard.

This entire management system is your business’s digital control room. We design this web app to easily fit with your existing ERP or CRM system. This integration is vital, as no company wants its employees to enter data into two different programs. Our web app lets you create users in bulk, set access schedules, and instantly monitor security alerts.

Unique Project Solution: Using Kerong NFC Locks

Kerong NFC Locks

This was a unique project where we created a complete smart access solution using battery-free NFC locks like the Kerong KR-NFC-CL5126.

The client needed a system for small cabinets, lockers, and workstation drawers that didn’t require frequent charging or maintenance.

To meet this need, we made the KR-NFC-CL5126 model central to our solution and developed a custom mobile app.

We established a workflow between the app and the hardware. A user could open the lock by tapping their phone's NFC, and the whole process worked without a battery or power source.

Our system would quickly verify access through the NFC tag and unlock the door. This model is powered by radio energy from the phone, making it completely maintenance-free.

In this solution, we included several key features in the app.

  1. The first feature was user registration and device pairing. This assigned each locker a unique digital identity.
  2. The second feature was NFC access management, allowing the administrator to choose which user could access which locker.
  3. The third feature was real-time logging, which tracked every unlock event in the app for the administrator to review later.
  4. The fourth feature was offline access, allowing locks to be opened via NFC even without a network.
  5. The fifth feature was fast setup mode, which enabled hundreds of lockers to connect to the system in just minutes.

This entire solution transformed the client's workflow. They no longer had to spend time replacing batteries, charging, or wiring. Staff enjoyed a seamless, zero-maintenance, and quick access experience. This project became one of our most successful and innovative NFC-based solutions.

Custom Solutions Using Kerong Smart Locks

Kerong offers many locks, but each client's needs are unique. At Adequate Infosoft, we believe that one solution does not work for everyone. That’s why we develop fully custom solutions using Kerong Smart Locks.

We are not just a service provider, we solve problems. First, we listen to your operational challenges. Then, we choose the right Kerong lock model, such as NFC, Bluetooth, or RFID, and create a complete system around it.

For instance, if you have a lot of small lockers that employees use frequently and you need a solution that removes the hassle of keys and tracks how often each locker is used.

Then we can design a complete custom system where employees open their lockers using their office ID cards, which are NFC-based and data will be sent to your management dashboard in real-time. This is just one example of how we can turn standard hardware into a tailored project solution for you.

Frequently Asked Questions

Is it possible to implement our existing KERONG locks?

Before proceeding, we need to know the specific type of lock and controller, firmware and protocol or SDK documentation. The check will confirm the availability of the necessary functions and any possible additional hardware.

Does every KERONG lock have a cloud API?

Integration method will depend on the device. The controller-based system, NFC lock system and connected lock system may have different interfaces. We check compatibility instead of assuming that one API fits all cases.

Can a QR code open a KERONG locker?

A solution can use a QR code as an application-level credential. A kiosk or phone validates it and requests the appropriate release operation. The reader, authorization service and controller connection must be included in the design.

Are battery-free NFC locks maintenance-free?

No. Removing the battery can remove battery-replacement work, but the lock still has mechanical parts and operating requirements. Phone compatibility, authorization and the supported energy-transfer interaction also need validation.

Does NFC unlocking function on both iPhone and Android devices?

The selected lock, application, and model of phone must be tested for compatibility. Having NFC on a device is not enough to guarantee an NFC unlocking process.

Can the system report that a locker contains a parcel?

The system can only notify users if it has been installed properly and have received confirmation about the results.

Which factors influence the project cost and timeline?

The primary elements include the availability of documentation, readiness of hardware, types of access, application size, integration with other systems, and the testing stage. A good estimation divides software development and electronics, installation, hosting, and maintenance.
