title: Saving credit card information in MySQL database?
body: <p>I want to allow my customer users to enter their credit card information so that I can charge them every month.</p>
  
  <p>I wonder how one should save this information?</p>
  
  <p>Should it be saved in the MySQL database ("user" table) or is this kind of information too sensitive and need to be stored in another place?</p>
  
  <p>I have no experience of this and would be glad if someone could advice me how to accomplish this.</p>
  
  <p>Thanks.</p>
