Yesterday, I received a flyer in my mailbox at the C21 office from a local lendor with the title “Protecting Your Credit”. It listed some things to watch out for to protect your credit card. One of the items said that hotel card keys contain your personal info on it (including credit card numbers) and the recommendation was not to turn these back to the hotel/motel but destroy them.
Unfortunately, this is incorrect and is one of those Internet e-rumors that has been going around since 2003. See this page:
