This vendor white paper defines modularity as the ability to configure and upgrade retail technology components independently. It covers hardware scalability for self-checkout, hybrid checkout, and payment modules, plus software openness via Open Retailing standards and modular service delivery. A case study shows one standardized platform supporting five store formats for a global retailer. The document emphasizes reduced deployment time, lower total cost of ownership, and faster response to shifts in consumer behavior and payment preferences.

Key takeaways

Modular POS hardware allows independent addition or removal of cash, digital payment, and security modules without full system replacement.

A single standardized platform can support multiple store formats while maintaining consistent software and service layers.

Upgradability reduces time and cost when shifting from cash to cashless or adding hybrid attended/self-service checkout.

Open interfaces enable the same software modules to run across different hardware devices through configuration only.

Modular services aggregate multivendor support and scale from installation to store modernization and closure.
