I'd like to build a machine for counting bills and during the counting process, I want to check whether the paper money is counterfeit or not.
Is the Raspberry Pi capable of doing this or would I be better off using a different board?
Thank you for your answers; after some testing with arduino, raspberry pi and beaglebone black, it seems that beaglebone black or zynq like platform be my choice. I need faster ADC processing for contact image sensor and this cannot be done with arduino or raspberry pi.
