Open L2 API interface is an abstraction of the card processing (alias L2), for EMV contact and EMV contactless systems. It is based on a simple set of primitives to ease L2 integration onto a payment application (alias L3).
That set of primitives supports Nexo Fast’s structures and dynamics.
What is not covered by OLA interface is:
Pin pad management: refer to manufacturer’s SDK to integrated use cases related to pin entry. Most of the time, proprietary callbacks must be defined using specific software signatures
Transit features: use manufacturer’s SDK to realize transit use cases. For example, if using Agnos Framework, refer to Callbacks API.
