KioEMVTransaction Class

KioEMVTransaction has been deprecated. Please use KioEMVDevice for new projects.

This class supports running Chip Card (EMV Card) Credit Card transactions in JavaScript. In order to use these functions, all necessary dependencies for the integration being used must already be installed and configured correctly. It is recommended that you use the standard EMV test page to verify that functionality beforehand.

Most functions run asynchronously, and fire a callback when they have completed their operation. This callback will receive a KioEMVResult object as an argument.

Finalizes an unconfirmed PreAuth transaction and returns the result via the OnKioEMVTransactionCompleted callback.
KioTransStates GetState(string)
Gets current device state.
int GetStatus(string deviceName = null)
Gets general device status.
KioDeviceStatus GetStatusEx(string deviceName = null)
Gets detailed device status.
bool Payment(int, string, string)
