Architecture
There are 8 callbacks available at different levels of Agnos Framework API:
...
AgnosEP
ApplicationSelectionMethod (entrypoint.h)
Name
ApplicationSelectionMethod
Scope
Contactless only. This call is performed right after PPSE selection. That callback can be used to overload mutual list management.

// See Agnos/selection.h for structure definition tByte *MLIndex, tBoolean CL |
...
) |
KernelSelectionMethod (entrypoint.h)
Name
N/AKernelSelectionMethod
Scope
N/AContactless only. This call is performed when requested kernel ID cannot be determined by the entry point. That callback can be use to map an undertermined kernel ID to a supported kernel ID.

AgnosMW
emvcallback (dataxchng.h)
Name
emvCallback
Scope
Contactless only. That callback can be used to control EMV contactless transaction flows. It is a normalized data exchange mechanism.
Description
This callback shall may be defined to control the contactless transaction flow from a payment application. It enables Data Exchange (DE) / Data Storage (DS) feature accross all contactless kernels in a normalized way. Use DF12 - Tags to Read - to define which tag(s) shall be looked up to give back control to the payment application.
Setter
Set tPaymentContext the field mDataExchange.mCallback defined by tPaymentContext. To enable DE/DS:
...
Set tPaymentContext mDataExchange.mDEList with the adress to an instance of
...
tDataExchangeList.
