I will integrate clover sunmi pax pos card reader sdk into your flutter app
Bhavya Bhatt
Sobre este Serviço
I help you connect real payment hardware to your Flutter app the part most developers skip.
Most Flutter developers can build a UI and connect an API, but few have integrated a physical card reader SDK into production. I specialize in exactly that: Clover, Sunmi, and PAX POS terminal integration for Flutter on Android and iOS.
What I do:
- Connect Flutter to Clover, Sunmi, or PAX SDKs via native platform channels (Swift/Kotlin bridge)
- Handle real transaction flow: card read, EMV processing, approval/decline
- Build reliable connection handling retries, timeouts, error states
- Support Android and iOS from one Flutter codebase
- Deliver clean, documented source code always included
Who this is for:
- Restaurant, retail, or delivery apps needing in-person card payments
- Existing Flutter apps needing hardware payment support added
- Startups building POS/kiosk systems
Payment hardware integration is unforgiving a broken connection means a lost sale. I test on real terminal hardware, not just simulators.
Message me your terminal model and I'll confirm feasibility before you order.

Perguntas frequentes
Which POS terminals/card readers do you support?
Clover, Sunmi, and PAX are my main SDKs. If you have a different terminal brand, message me your model number and I'll confirm before you order.
Do I need to provide the physical hardware for testing?
Yes, or access to it remotely (TeamViewer/AnyDesk). Card reader SDKs behave differently on real hardware vs. simulators, so I test on your actual device to guarantee it works in production.
Can you integrate this into my existing Flutter app, or do you only build new apps?
Both. Most of my orders are adding POS integration to an existing app — just share your repo or codebase and I'll integrate into it directly.
Do you handle payment processing itself, or just the connection to the reader?
I handle the SDK integration and transaction flow (card read, EMV processing, approval/decline response). Your payment processor/merchant account setup is separate and should already be configured with the terminal provider.
What if my terminal SDK has no public documentation?
Send me whatever SDK docs or sample code you received from your provider (Clover, Sunmi, PAX all give developer packages). I've worked with limited or vendor-only documentation before.
Is source code included?
Yes, always. Full source code is included in every package with no extra charge.
How long does delivery take if I need both Android and iOS?
Standard and Premium packages cover both platforms — see delivery times listed there. Basic is single-platform only.
What do you need from me to get started?
Your terminal brand/model, your existing Flutter app (if any), and your SDK credentials/developer account access from the terminal provider.
