stopCardDetect method is a utility command used to manually deactivate the terminal’s reader. This serves to maintain control over the user experience when a transaction is abandoned or a different workflow is required.
Use this method to:
- Terminate the detection phase if a customer cancels the operation at the pump or POS.
- Close the reader safely if a locally managed timeout is reached without user interaction.
- Clear the reader state to prepare the terminal for a different command or a return to the idle screen.
