Why augment instead of hire?
Direct recruitment of in-house Kotlin engineers for verifone mobile pay locks you into long notice periods, payroll tax, and unproductive bench time. Outstaffing with Smartbrain.io gives you instant capacity without head-count liability, access to a curated pool of PCI-DSS experienced developers, and transparent hourly billing you can scale up or down every sprint. Our engineers remain full-time dedicated to you, yet we handle HR, hardware, benefits, and continuous upskilling—so you pay only for delivered code, not hidden overhead. CTOs keep architectural control while we absorb the admin load, turning cost centers into predictable OPEX and shrinking product road-maps by up to 30 %.

What Technical Leaders Say
We struggled to retrofit Kotlin coroutines into legacy Verifone SDKs. Smartbrain.io supplied two seniors within 6 days. They wired Jetpack Compose screens, built EMV flows, and merged code in the first sprint, trimming QA cycles by one-third. Productivity jumped instantly while my in-house Android team focused on roadmap items.
Erin Wallace
Mobile Engineering Manager
BrightLane Transit
Their augmented team replaced brittle Java with Kotlin Multiplatform and Ktor APIs, ending nightly crashes. Onboarding took 4 hours; stand-ups were seamless. We shipped tap-to-pay before holiday season and saved 20 % versus local contractors.
Justin McCarthy
CTO
ShopSquare Inc.
Smartbrain.io’s Kotlin experts hardened our tokenization layer using coroutines and Flow, reducing transaction latency. Integration with Verifone MX was flawless and our finance dashboard saw 18 % fewer chargebacks. Couldn’t have hit PCI audit without them.
Monica Hughes
VP Product
FinGuard Solutions
Needed NFC payments inside driver tablets. Two Smartbrain Kotlin devs joined via Slack next day, delivered a clean MVVM module, and paired with our CI/CD pipeline. Throughput rose 27 % and my DevOps lead said onboarding was the smoothest yet.
Daniel Price
Head of Engineering
FleetWave Logistics
We processed 65k check-ins daily; thread leaks killed sessions. Their KMM specialists profiled code, swapped blocking calls for coroutines, and introduced Flow retries—downtime fell to 0.01 %. Contract flexibility let us taper headcount post-launch.
Samantha Reed
Technical Director
StayWell Resorts
Smartbrain.io covered gaps in cryptography and Verifone SDK. Senior Kotlin architect built test harnesses, coached our juniors, and met every audit artifact. Audit prep time shrank by 50 %; board loved the cost transparency.

Heritage Community Bank
Industries We Empower
Fintech & Banking
verifone mobile pay Kotlin developers build PCI-compliant tokenization, 3-D Secure flows, and EMV certification modules, handling real-time fraud rules and legacy core integration. Outstaffing ensures rapid scalability during audit crunches without permanent head-count.
Retail & eCommerce
From in-store NFC kiosks to omnichannel checkout, augmented Kotlin POS teams integrate Verifone Cloud Services, loyalty APIs, and inventory microservices, delivering seamless tap-to-pay experiences that boost basket conversion.
Logistics & Fleet
Drivers accept contactless fuel payments via embedded tablets. Our outstaffed verifone mobile pay engineers craft low-latency Kotlin modules with offline caching and token re-sync for poor-signal routes.
Hospitality
Kotlin-powered kiosks enable room charges and upgrades on Verifone terminals. Remote teams manage OTA integrations, key-card pairing, and GDPR data flows while hotels keep CAPEX lean.
Healthcare
HIPAA-aware developers add co-pay collection via Verifone Engage, securing PHI through encrypted Kotlin channels and FHIR interfaces, all under short-term augmentation contracts.
Transportation
Transit agencies deploy tap-on-tap-off ticketing. Our Kotlin specialists optimize NFC, Fast EMV, and background fare reconciliation, trimming queue times during rush hours.
Insurance
Agents collect premiums on mobile devices. Outsourced verifone mobile pay Kotlin coders integrate secure payment SDKs into claim apps, accelerating policy issuance.
Food & Beverage
Quick-service chains roll out self-order kiosks; Kotlin coroutines keep orders and Verifone receipts in sync even at lunch-rush volumes.
Utilities
Field technicians accept service fees on rugged Android handhelds. Augmented teams layer Verifone payment modules over ISO-8583 gateways, reducing cash handling risks.
verifone mobile pay Case Studies
Stripe-Like Checkout for Regional Bank
Client: Mid-size retail bank
Challenge: Legacy core could not handle real-time ‘verifone mobile pay’ tap-to-pay transactions.
Solution: A two-developer Kotlin squad embedded remotely, created a Ktor microservice bridging Verifone Cloud API with the bank’s COBOL host, and introduced coroutine-driven batch failover. They paired daily with in-house security team and delivered PCI evidence.
Result: 42 % latency reduction, 0 security findings, and rollout to 150 branches in 11 weeks.
Kiosk Rollout for National Retailer
Client: 3,000-store apparel chain
Challenge: The Java kiosk app crashed when adding ‘verifone mobile pay’ wallet support.
Solution: Four Smartbrain Kotlin devs rewrote UI in Jetpack Compose, isolated payment flows in MVI architecture, and added automated Cypress tests. Coordination occurred over Slack with nightly demos.
Result: 35 % faster checkout, 99.98 % uptime, and $1.8 M upsell in the first quarter.
In-Cab Payments for Logistic Fleet
Client: 12,000-vehicle trucking firm
Challenge: Tablets dropped ‘verifone mobile pay’ sessions in low coverage zones.
Solution: A single senior Kotlin engineer implemented offline token queuing with Flow and encrypted Realm storage, syncing once 3G returned. Dev joined within 5 days under outstaffing.
Result: 87 % fewer failed payments and annual fuel theft losses down by $2.3 M.
