Introduction

Knot's merchant connectivity platform provides financial institutions and other businesses of all sizes with technology that connects end users with their online merchant accounts. CardSwitcher, for example, allows users to quickly and securely update their credit and debit cards on-file with merchants. This allows card issuers to improve and maintain top-of-wallet status across merchants.

Knot's SDK handles credential validation, multi-factor authentication, and error handling at all supported merchants. The SDK is compatible across iOS, Android, React Native, Flutter and all modern web browsers.
