Why one API across three devices matters more than any single device
Integrate once. Every counter you'll ever meet is already covered.
Hardware families usually grow the ugly way: each new device arrives with its own SDK, its own quirks, its own integration project. Software companies learn to dread the second device more than the first.
Kuvex made the opposite bet. The KReader on a desktop, the Cloud Terminal on a counter, the Web POS Pad running your whole register — all three answer to the same payment object. Which device executes a payment is routing, decided at runtime, not integration, decided in your codebase.
Why this compounds
Your merchants are not uniform. Some want the cheapest possible device next to an existing setup; some want a turnkey terminal; some want the flagship pad. With one API, you serve all of them from a single integration — and when a merchant upgrades their hardware, your code doesn't change. Nothing gets re-built, re-tested or re-certified on your side.
For a software company, that turns hardware from a series of projects into a catalog. Pick what fits each merchant; the platform sorts out the rest. The integration you did on day one keeps paying for itself with every device we ship.
