Icon Backend

Intuitive backend

Depending on the software used, the CubeAdmin Centre provides corresponding functions as well as management and analysis tools.

Flexible surface design


The user interface can be customised to the desired design.

Cloud Software. Secure and efficient.

With our cloud solution, you save costs compared to on-premise solutions. The security of your data and the up-to-dateness of the software is increased by the professional support of the ISO 27001-certified data centre.

Cloud solutions are significantly less susceptible to faults or can be rectified very quickly if the worst comes to the worst. You don't have to put additional strain on your IT and save on personnel and working hours.

You get a secure, AES256-encrypted, GDPR-compliant, reliable and cost-effective solution.

Interfaces to your systems.

The intelligent lockers can be integrated into existing software solutions such as ERP, CRM and shop systems, employee databases and much more via our interfaces (API).

Safe is safe

Encrypted data connections via APN in the mobile network, certified cloud data centres and much more make our VC Cloud solution a secure choice.


Our solutions are GDPR-compliant and our cloud data centres are located in Ireland and Germany.

cloud-based microservice architecture:

  • Scalable – it can be scaled horizontally at any time. 
  • Reliable – Essential services are distributed across multiple sites or closely monitored.
  • Current – through our continuous delivery process based on Kanban, all our customers are always up to date.
  • Secure – AES256 encryption enables secure data transmission and prevents the opening of compartments by third parties.

CUBE-Controller with REST API

Our CUBE controller brings electronic lockers to the web via state-of-the-art REST API. By using a Java-based microservice architecture, the highest flexibility in the solution as well as platform independence are achieved.

You can also implement projects yourself for our App Host. Each lock is accessible via a globally unique address (URL) and offers an extensive REST API. We can guarantee fast and easy implementation as well as stable operation through the power of diverse software libraries that are available to us.

Variocube Cloud architecture.

The most advanced cloud solution for smart locker systems.

Applications on the Smart Locker

The applications run locally on the Locker and communicate with the Cube Controller in real time via the Application API. 

The range of functions can be customised in special projects.

Cube Controller manages the system

The Cube Controller monitors the system, manages lock drivers, occupancy and much more. The Cube Controller communicates with the VC Cloud in encrypted form in real time.

VC Cloud

The Variocube Cloud is GDPR-compliant and the data centres are located in Ireland and Germany. The data is encrypted, as is communication via the interfaces.

Cube Admin Centre

The CubeAdmin Centre manages all lockers and is the central administration point for customers' smart lockers. General functions and, depending on the application being operated on the lockers, extended management options (inventory, rental prices, etc.) are available.

Connecting external services (API)

There are various options for connecting your systems:

  • Your own IT systems can communicate directly with the CubeAdmin Centre via an API, with Variocube only taking care of administration in the background. Only your systems are visible to your customers and employees.
  • The existing IT systems communicate with the Variocube WebApps via the API and provide the requested data. The Variocube WebApp is the central point of contact for users.

Which services can be connected?

There are no limits to the systems that can be connected. We already work with a wide range of CRM, ERP & shop systems (e.g. SAP, SAP-MM), employee databases and access management systems. SCLogic & Pitney Bowes are connected for internal parcel distribution.

Cube WebApps

  • Users use the corresponding web app to interact with the service offered.
  • WebApps run in the browser window; no separate applications need to be installed on the end devices.
  • Communication with the CubeAdmin Centre and the systems connected via the API is encrypted.

Thinking big?

No problem! Our web architecture allows you to control any number of locks in any number of locations around the world.

General Functions

Sending the storage and pickup codes by e-mail or SMS

Integration of multiple languages in the back and front end.



  • Occupancy display
  • Reminder functions
  • extensive maintenance functions
  • Task lists for service personnel
  • Web interface for support



All transactions are logged on the CUBE host and can be transferred to third-party systems as needed. For example, for pharmaceutical industry, food industry, clean room technology, safety technology, ...

State-of-the-art web interfaces leave nothing to be desired when it comes to integration into your systems. Several systems can also be connected. The CUBE Admin Center is used to set which app may access which lockers.

The VARIOCUBEs are equipped with industrial grade routers and can be connected via LAN and WLAN, as well as via LTE. Also redundant or failover connections are possible at any time.

As a rule, purchases and services are paid for. If required, we can offer you a complete online payment solution with credit card, PayPal, direct transfer, SEPA direct debit etc.

There are centrally controlled updates both for the running systems and for newly installed CUBEs. A CUBE goes online with its original state and shares its ID. The CUBE Admin Center gives it its functions and initiates all installations and updates.

Local user administration, user roles, connection to central databases, LDAP, time-controlled access, and much more.

No two requirements are the same. True to this motto, we have the possibility to teach the VARIOCUBEs all the tricks to meet your business requirements.

Not only is the connection of the VARIOCUBE to your systems a requirement, the design of the application that runs on the VARIOCUBE's display is also decisive for your business success. Imagine installing an app on the CUBE in the same way as you do on your mobile phone. The CUBE App Host is the platform. Your HTML5 application is the app!
