Overview

The goal of the AgnosSP library is to address dual processor architectures where Agnos is only accessible through a serial interface, for exemple Agnos integrated in the Secure Element of a Device.

NOTE: This guide focuses on communication between the L2 Certification Application (Kizis) and the Agnos Services

Single Chip Device

Traditional Payment Terminals have single Microcontrollers (or Microprocessors) on which Applications and Agnos can both coexisting:

Open

Single Chip Device

Integration of Agnos with this type of Architecture may be done either through the API described in Merchant/Operator Application Integration or through the OLA API.

Dual Chip Device

New Payment Terminals (such as Android Devices) may require presence of a Secure Elements (or additional Microcontrollers) to prevent access of sensitive data from rogue Application (PCI compliance)

In such architectures, Kizis doesn’t have direct access to the Agnos Rich API, AgnosSP allows such access regardless of the type of serial interface (ex: USB, I²C, UART, SPI, RS232…):
