Presumably "easier and cheaper" implies "easier to fake" too. I guess the NFC solution has enough cost attached to it to make replicating it impractical for counterfitters?
E.g. in web system you can assign owner to barcode (product). Different scenarios if owner is known before purchase or assigned later. All other trials to validate product id as unique should fail and client might request return of money.
this requires a mean to identify where the unique good is (if it exists at all). would rfid fix this? hmmm shrug
