Something like half of the supermarkets in Denmark scan all money bills they receive supposedly with the purpose of defeating counterfeit money. However it could easily do OCR on the serial as well. Combine that with CCTV records, and and it does not offer much more privacy than credit card payments.
Ironically I started to appreciate it, after I received a fake bill from a different store.
