Single Chip Device
Traditional Payment Terminals have a single Microprocessor Microcontrollers (or Microprocessors) on which both the L3 Level 3 Payment Application and Agnos are can both coexisting:
...
In this type of architecture, the Level 3 Payment Application (Level 3) may is able to call Agnos Services directly through the Agnos Rich API (Agnos Rich 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, the Level 3 Payment Application doesn’t have direct access to the Agnos Rich API.
AgnosSP will provide such access regardless of the type of serial interface (ex: USB, I2C, UART, SPI, RS232…):
