Store membership card or loyalty cards must be banned at stores with physical locations for many reasons:
1. Too many cards in customers' pocket can INJURE the back.
2. Customers giving personal information at checkout can cause ID theft by other customers or store employees.
3. Customers having to use membership card passwords or other id numbers often be confused with debit or credit card PIN numbers, causing more mistakes or data to fall in the wrong hands.
4. Stores often can change their membership rules to exploit the customer. For example the store may change the rules break the promis they made to not use phone numbers for marketing purposes.
5. Defamation or Loss of privacy. For example, if you buy cigaretts for a friend, you may find your health insurance gets cancelled.
6. Sick of the hassle of so many membership cards.
7. Nearly every grocery store in some towns ask customers to sign up for another membership card. Customers who refuse end up paying more.
