title: Secure Credit Card transactions in app
body: <p>I want to be able to sell products (via credit card) to people using my app. It's easy enough to put some EditTexts in and get them to give me their details but the issue is security of course. What is a good way to go about doing secure credit card transactions in app?</p>
  
  <p><strong>My Big Concern</strong> - Someone else makes a fake app that looks the same, with the same icon and app name and gets potential users to download their fake app and steal their credit card information. (Can people maybe even have the same developer account name?)</p>
  
  <p><strong>What I know so far</strong> - The package names of apps served off Google Play are unique so a user could identify if the package name is not what it should be. This isn't a good solution for the typical user though.</p>
  
  <p>I'm not planning on storing the credit card details or anything. I just want to be able to do once-off card transactions securely. Any advice would be super welcome and receive much upvoting.</p>
