Why outstaff instead of hiring directly?
Skip the months of recruiting, interviewing, and onboarding. Smartbrain.io plugs pre-vetted JavaScript engineers with proven contactless payment integration track records straight into your sprint, so you start shipping features this week—not next quarter. You pay only for productive hours, keep full IP ownership, and scale teams up or down without severance, payroll tax, or geographic limits. Our specialists already understand NFC protocols, EMV tokenization, and PCI-DSS, so your internal team focuses on core roadmap while we handle the payment layer—at a predictable, transparent rate.

contactless payment integration case studies
MetroPay One-Tap Rollout
Client: Regional POS provider serving 2,500 retail locations.
Challenge: Legacy terminals lacked contactless payment integration, stalling enterprise deals.
Solution: Two augmented JavaScript engineers (React & Node) built an EMV-compliant NFC module, refactored firmware APIs, and automated testing within Jenkins pipelines.
Result: 43% faster checkout, 0 PCI audit findings, and $3.2 M in new contracts signed within 4 months.
CityGo Fare-Capping Platform
Client: Urban transit authority processing 1 M rides/day.
Challenge: Existing app couldn’t support contactless payment integration across buses and subways.
Solution: Smartbrain formed a squad of three TypeScript specialists who integrated Visa MTT SDK, designed Kafka event streams, and implemented offline validation logic.
Result: Ride boarding time dropped by 28%, and fraud incidents fell 19% within one quarter.
QuickBite Self-Order Kiosks
Client: Fast-food chain with 400 restaurants.
Challenge: Kiosk vendor missed deadlines for contactless payment integration into new self-service hardware.
Solution: Our senior Vue.js developer optimised POS firmware APIs, added Apple Pay & Google Pay, and led security hardening.
