Instant payment, drop-in.
Plugins for WooCommerce, OpenCart, CS-Cart. A clean REST API for everything else. Sandbox-first, signed callbacks, no card-form to build.
A checkout that doesn't ask for a card number.
For e-commerce, the friction is the checkout form. Card number, expiry, CVV, 3DS challenge, redirect, return, retry on decline — five chances to lose the order.
miaPOS e-commerce checkout has none of that. The buyer clicks Pay, the page redirects to a single screen with a QR (desktop) or a deep link (mobile), the buyer confirms in their banking app, the merchant gets a signed callback within seconds. Cart-to-paid in under 10 seconds end-to-end.
Three integration paths: plugin (zero code — install, paste API key, done), PHP SDK (a couple of hours), or direct REST + signed callbacks (for everything not on the supported stacks). All three talk to the same sandbox-first API.
How it works.
From the cashier's tap to the merchant's bank account.
For any web shop where the rail matters.
E-commerce checkout is the right answer when the merchant already has a website.

Lower fees than cards = more goes to the cause.
