Callback OnKioEMVStateChanged (KioTransStates)
This callback is fired whenever a framework alerts KioWare that the device is performing a different stage of the transaction.
The new state that the EMV transaction has just entered.
The callback will be fired once per operation in every frame of every browser. Certain frameworks only report a limited subset of device states changes.
KioWare for Windows version 8.7 or greater.
