Welcome to KABC Payment Tools — a free, browser-based toolkit built for payment developers and security professionals. Every tool runs entirely in your browser: no data is ever uploaded or stored on any server. Whether you're testing cryptographic algorithms, building HSM integrations, or debugging EMV transactions, KABC gives you the same capabilities as commercial tools at zero cost.

About

KABC is a personal project by Robert Peng, a Toronto-based payment developer with over a decade of experience in the payments industry. It started as a collection of internal scripts and has grown into a comprehensive toolkit used by developers worldwide. The project has no external funding — it runs entirely on personal time and resources. If KABC has saved you time or helped you solve a problem, a small donation keeps it running and growing. Even $1 helps cover server costs and motivates new features. For questions or feedback, reach Robert at kabcpay@outlook.com.
