About the Knox POS SDK

The Samsung Knox Platform for POS provides specialized APIs to POS partners to assist with the development of secure, customizable, and easy-to-use payment apps. To provide security, the mPOS platform supports:

  • Key attestation for devices and mobile apps.
  • App security through Samsung Knox.
  • An additional layer of security during PIN entry through TUI (Trusted UI) control.
  • TEE (Trusted Execution Environment)-based cryptography for authentication.

For a comprehensive overview of the SDK’s functions, see Features.


The Knox POS SDK can be used by a wide array of developers:

  • Payment Service Providers (PSPs) — These developers provide a secure payment service to device users as solution vendors or acquirers.
  • Independent Software Vendors (ISVs) — These developers create the payment solution for device users.

Knox POS SDK is supported on the following Samsung devices:

  • Smartphones: S22, S21, XCover6 Pro.
