I will do pos terminal programming

At Grado, we build payment applications for POS terminals that are reliable, fast and ready for certification.

We have hands-on experience building applications and backend infrastructure for all kinds of POS terminals (Android or Linux based, Mobile POS, Soft POS, etc).

We can help you trough all the stages of the software development - from design and architecture, trough implementation, testing, security auditing to assistance with payment providers certification process.

Some of the POS terminal vendros we have worked with are: PAX, SUNMI, Nexgo, Wiseasy, Ciontek, and Feitian.

We treat client information, source code, and integration details with the same rigor as the payment data our applications handle. All engagements can be covered under NDA, and we're comfortable working within your existing confidentiality and vendor security frameworks rather than asking you to adapt to ours. Terminal credentials, API keys, processor documentation, and any proprietary specs shared with us are handled on a strict need-to-know basis and are never reused, referenced, or disclosed outside the scope of the project.
