## Overview

This is a configurable KLCiS voucher-store page: customers choose an uploaded voucher denomination and use the store with the operator’s KLCiS API key. The README also describes hosting the page online or offline and integrating it with hotspot platforms. The sampled QR script is a QR-code generation library; the HTML source was not provided, so its exact API calls, checkout steps, and whether it invokes that library cannot be verified.

Main entry points: [`store.html`](https://github.com/darkhoundz/klcis-qr-api/blob/master/store.html) (Voucher store)
