I suggested that this might be happening and had someone pretty quickly dismissing that the Chinese ATM maker here (oddly specifically, and happens to be my bank ATM here in Wyoming which I never stated), would put in the extra hardware for that. The hardware is mostly there already for imaging (how does the machine verify it's valid cash?) and it analyzes digits with a small neuronet for cheques (decades old tech). It's all there, just write some back-end stuff, and process bill images at a colocation if the ATMs don't have the horsepower to get the serial number locally.
