SW Overview
The software (SW) for the embedded products consists of two separate programs that
coexist in flash memory:
The boot loader, which is started at power on, is not field upgradable. It is
programmed into flash when the module is manufactured.
The application firmware, which implements the actual reader functionality, is field
upgradable.
