...
A payment application detects whether a contact or contactless application will be triggerred
A payment application implements the logic to select a final application based on OLA services
A payment application configures the EMV parameters based on the final selection
...
Interfaces
Interface | Description |
|---|---|
ola.h | This interface presents different administrative services |
ola_emv.h | This interface presents common services required to support contact and contactless card processing |
ola_publickey.h | This interface allows a payment application to intialize a L2 stack with a set of public keys required to execute an EMV transaction flow (contact and contactless) |
ola_contact.h | This interface is meant to support contact transaction flow |
ola_contactless.h | This interface is meant to support contactless transaction flow |
ola_tags_dictionary.h | This header lists all the tags that are specific to Nexo Fast and consequently subject to a translation for further indexation in the L2 stack |
