Me Card provides you a tool to make an inventory of every campaign you no longer want to be a part of and helps you to withdraw your details from their database.
Me Card also will help you to register at the do-not-call-me register so you no longer suffer of companies who persistently phone you for marketing of products you are not interested in.

By doing so you will be able to offer your data to companies who have your permission to contact you, if they have an offer you are interested in. And they will pay you for your permission to call. That is a great Me Card advantage!
