I think there should be legislation against requiring consumers to enter their phone number or club card for sales. At the very least it should be disallowed to record all your purchases with your identifying information since all of this data from all different stores is being collected and analyzed to give a very personal picture of a particular person. I understand the business needs of understanding what is bought--but targeting to an individual rather than general demographics of a store is way to "Big Brother" and is an invasion of privacy.
