In supermarkets and retail, every second counts. Reducing checkout times, minimizing errors, and being able to scale new technological solutions without interrupting operations are key goals to protect margins and improve the shopping experience. The piece that makes all this possible—and is often underestimated—is the connectivity between cash-handling devices (recyclers, dispensers, acceptors) and central systems (POS, ERP, WMS).
Common Challenges at Checkout
- Devices from different manufacturers and generations, each with proprietary protocols.
- Integrations that require modifying the POS or creating dependencies on the manufacturer.
- Slow local troubleshooting (issues resolved manually) and deployments that get stuck when the store network expands.
These frictions increase human errors, service times, and operating costs.
How Connectivity Solves This
The effective solution is an abstraction layer (middleware) that standardizes communication between the POS and cash modules. Well-designed middleware translates proprietary protocols into a standard API (REST/WebSocket), provides remote management and diagnostic tools, and supports multiple configurations without touching the POS logic.
This enables the integration of heterogeneous devices, automation of the cash flow, and scalable deployment of the solution across the store network. These are precisely the services that Serquo has been offering for more than 30 years of experience in device connectivity for cash management.
Tangible Benefits for Supermarkets and Retail
- Checkout efficiency: Automated processes for validating, dispensing, and storing cash reduce transaction time.
- Fewer errors and greater traceability: Automatic recording of operations and direct reconciliation with central systems.
- Scalable deployment: The standardized interface allows adding devices or stores without reworking integrations.
- Reduced dependency on manufacturers: Freedom to choose equipment based on cost/functionality without disrupting operations.
- Proactive operation: Remote monitoring and alerts that anticipate failures and shorten repair times.
Quick Checklist to Get Started
- Inventory of in-store devices and protocols.
- Prioritize solutions that do not require modifying the POS.
- Run a pilot in 5–10 stores before mass deployment.
- Train the technical team in integrations and maintenance.
A solid connectivity solution is the backbone that enables secure, efficient, and scalable cash-handling automation. If you’d like to explore how to adapt this to your store network (technical assessment, pilot, or middleware development), we can support you with consulting, development, training, and continuous support.
