Scan&Go Mobile Self-Checkout

for Retail supermarket chain

Industry: Retail

Location: Europe

Platform: React Native

Project Type: Self-Checkout MVP

Client Background

Scan&Go started as a straightforward problem: cashier lines got long, and shoppers noticed. The retailer, a supermarket chain with stores across Europe, needed a way to speed up checkout without adding staff or expensive hardware. One Logic Soft built the MVP with more than that one fix in mind — it also had to work across different regions and double as a channel for personalized offers.

Delivery Objective - Cut peak-hour checkout queue times
MVP Rollout Scope - An MVP designed to run across many stores
Engagement Model - Full-cycle mobile app delivery

The Checkout Bottleneck

Rush hour slammed the checkout lines hard
Traditional cashier lanes couldn't keep up with the shopper surge
More checkout throughput always cost more
Handling the extra volume meant hiring more staff or adding more lanes
Self-checkout kiosks weren't cheap either
Buying and maintaining that hardware put real strain on the store budget
Checkout had no room for personalized offers
The old checkout process had no way to surface deals mid-purchase at all

Solution & Execution

The MVP lets customers scan items, drop them into a digital cart, and pay without reaching a register. Under the hood: React Native, Java 17, PostgreSQL. Scope stayed tight on purpose - ship something that works, then expand region by region.
