title: Parse Credit Card input from Magnetic Stripe
body: <p>Does anyone know how to parse a credit card string input from a Magnetic Card Swiper?</p>
  
  <p>I tried a JavaScript parser but never got it to work.  This is what the input looks like.</p>
  
  <pre><code>%BNNNNNNNNNNNNNNNN^DOE/JOHN
  ^1210201901000101000100061000000?;NNNNNNNNNNNNNNNN=12102019010106111001?
  </code></pre>
  
  <p>The N's are the credit card number.</p>
