bakong-khqr

https://github.com/VandyTheCoder/bakong-khqr-ruby

A Ruby port of the official bakong-khqr JavaScript SDK (https://www.npmjs.com/package/bakong-khqr). Generate Individual and Merchant KHQR payloads, decode existing KHQR strings, verify the embedded CRC-16/CCITT-FALSE checksum, and call the Bakong Open API to check accounts and produce deep links. Zero runtime gem dependencies — uses only the Ruby standard library.
