Overview

The Arkos Framework is defined at a global level so that there is no hypothesis made on the type of platforms running it. Basically, Arkos provides a set of interfaces that facilated the build and the integration of a card payment acceptance application on any platform.

...

  • Arkos API, Arkos' Payment API : a set of services driving the Payment as an extension of a Sale function

  • Arkos CallBacks, Arkos' Payment CallBacks : a set of callbacks extending Arkos' behavior so it can be ported onto a specific platform

  • Open L2 API, OLA API : a set of services driving the card processing

For more information about the Arkos API, please go to the https://teamamadis.atlassian.net/wiki/spaces/ADG .

Component

Description

MerchantApp

The Merchant Application is responsible for:

  • UI Interface

  • Input of Amount, service and additionnal payment parameters to start a transaction

  • Printing

  • Configuration of the merchant application

  • Input of TMS Host information for configuration

Arkos Inteface

The Arkos interface provides a set of JNI functions and callbacks between the MerchantApp and the Arkos Framework.

Arkos Framework

The Arkos Framework includes the Arkos Payment Core library coded in C/C++. It is responsible for:

  • Communicating with TMS Host to get payment configuration

  • Receiving Transaction Request from Merchant Application

  • Execute Payment transaction according to local schemes requirements (based on nexo-FAST)

  • Card detection and interaction with L2 EMV

  • Communicating with the Acquirer Host for authorization

Platform

Physical device on which the payment application is installed.
