Integrating Agnos - or Developing a payment application (L3) relies on:

• A previous successful platform integration (DEVICE realization) validated from unit tests vectors execution

• A first L2 qualification demonstrating that the system is mature enough to start L3 development (i.e. a full L2 TA is not required to start as long as significant use cases can be executed)

Agnos programmation paridigm is systematic:

1. Set pre-conditions

2. Trigger a transaction

3. Get post-conditions

Agnos provides a rich API. The following gives some hints to built from scratch a first application integrating Agnos.

Set pre-conditions

System Initialization

This level of initialization shall be performed only once usually at system’s start-up time.

• gpiMain

• gpiInitializeHSM

• gpiInitializeDisplay

• gpiInitPolling

Transaction Initialization

Trigger a transaction
