A Common Language for Pharmacies — A Unified System for Pharmacies

Imagine your pharmacy team speaks English, but the warehouse robot only speaks German, and your inventory management system only speaks French. Without a translator, nothing would work.

That's exactly the problem WWKS2 solves. It is a standardized communication protocol — a mutually agreed-upon "language" through which different systems in the pharmacy can communicate with one another. This standard is developed and maintained by a consortium of leading pharmacy technology providers, with the goal of making devices and software compatible across manufacturers.

In practical terms: a CareApo24 terminal can communicate via WWKS2 with dispensing robots from all major manufacturers (ROWA, Knapp/Apostore, KLS, Swisslog Gollman, etc.). The standard works independently of the manufacturer — similar to how USB works with computers.

What Happens Technically — Without the Technical Jargon?

Let's walk through a concrete example from everyday pharmacy life:

A customer stands in front of the CareApo24 terminal at 10 p.m. She selects an OTC product, pays contactlessly by card, and within seconds the machine dispenses her product.

What happens in the background runs in four simple steps:

1. Availability is checked. Only products that are currently available and ready for purchase are shown to the customer.
2. The order is forwarded. The CareApo24 terminal sends a request via the WWKS2 interface to the pharmacy robot: "Please dispense this product."
3. The robot fulfills the order. The dispensing robot receives the request, retrieves the correct product from storage, and delivers it to the dispensing outlet.
4. Inventory is updated. Once the product has been dispensed, the robot confirms: "Done. Inventory has been adjusted." This information flows directly into your inventory management system.

All of this happens in seconds — fully automated, without any staff intervention required.

Why Is This So Important for Pharmacies?

Anyone who has experienced how laborious it is to get two systems without a shared interface working together knows: incompatibility costs time, money, and frustration.WWKS2 addresses this problem at its core. Because the standard is widely adopted in the industry, pharmacies no longer need to ask when choosing a new terminal: "Will this work with our robot?" — they can assume that WWKS2-compatible systems will work together.

For pharmacy equipment suppliers, this also offers a clear advantage: integrating a CareApo24 terminal into an existing pharmacy system is predictable, reliable, and requires no complex custom solutions.

What CareApo24 Enables via WWKS2

The WWKS2 integration is not a technical add-on — it is the core of 24/7 operations. This connection makes it possible to:

• Make OTC products available around the clock without anyone needing to restock or intervene in the warehouse
• Update inventory levels in real time, so your inventory management system always reflects the current status
• Enable seamless collection: products set aside for customers after a consultation can be securely and compliantly collected at the terminal using a personal pickup code
• Eliminate duplicate effort: sales, dispensing, and stock movements are automatically recorded and do not need to be entered manually

In short: WWKS2 connects your existing robot with the CareApo24 terminal and transforms two standalone systems into one integrated, end-to-end solution.

What Does This Mean for Pharmacies Without a Warehouse Robot?

Not every pharmacy operates with a fully automated dispensing system. Modernization is still possible here.

In this case, CareApo24 can be operated as a standalone system — using the CareApo24 Shelf, a semi-automated shelving unit that serves as the internal storage for the terminal. The workflows are identical to those used with the WWKS2 interface and can be expanded with a warehouse robot at a later stage. The CareApo24 Shelf can also handle products that — due to size, texture, or weight — cannot be managed within a standard dispensing robot.

Conclusion: Less Complexity, More Reliability

WWKS2 is a valuable and practical technology that standardizes and simplifies the pharmacy workflow in a straightforward way.

Systems work together. Without friction, without workarounds, without manual intervention.

For pharmacies looking to extend their service to 24/7 operations, WWKS2 compatibility is one of the most important criteria when selecting a solution. It determines whether a terminal can be truly seamlessly integrated into existing operations — or whether it remains an isolated solution that creates more effort than it saves.

CareApo24 has been working with this open, well-established standard for many years and continuously implements all updates and new developments in full.
