Hire Point of Sale Compliance Solution Experts

Client: 430-station fuel retailer

Challenge: Regional CFO needed a point of sale compliance solution to stop costly chargebacks linked to mismatched dispenser and POS data.

Solution: Our augmented JavaScript squad implemented Node.js ingestion services streaming dispenser logs to a central Kafka bus. React dashboards displayed real-time settlement discrepancies while automated test harnesses validated EMV transactions nightly.

Result: **19%** drop in chargebacks, **40%** faster monthly reconciliation, and roll-out completed in eight weeks without hiring a single full-time developer.

Client: National pharmacy chain (1,200 stores)

Challenge: Compliance team lacked immediate visibility; audits of each POS terminal took weeks and frequently missed anomalies— jeopardising PCI certification and HIPAA fines.

Solution: Two Smartbrain TypeScript devs integrated WebSocket streams from each terminal, normalised data via AWS Lambda, and wrote Vue.js dashboards highlighting non-compliant events within seconds.

Result: **94%** reduction in audit preparation time and zero critical findings during the annual PCI-DSS assessment.

Client: Global luxury apparel brand

Challenge: Expensive on-prem card readers expanded PCI scope; CTO sought a cloud-first point of sale compliance solution without overhauling front-end experiences.

Solution: Three augmented JavaScript engineers refactored the React-Native POS app to tokenise card data at swipe, moving sensitive flows to a PCI-Level-1 gateway. They added Cypress tests to enforce compliance on every release.

Result: **38%** smaller PCI audit scope, **28%** faster checkout, and annual compliance costs slashed by **$480K**.
