The customer would have to be identified first and submit his own fingerprints, as well as register credit cards with the grocery store. But then a Pay By Touch system became quite popular among the store regulars. According to CNET, "one man even drove 400 miles to use the technology". The store also reports 0% of such transactions being fraudulent."
