title: How does Chrome detect Credit Card fields?
body: <p>In some forms, Chrome autofill prompts with Credit card autofill.</p>
  
  <p>EDIT:Adding screenshot. This is not the same as browser autocomplete. You need not have entered the value in the same form before.</p>

  <p>How should I write my HTML form so the browser detects these as Credit card fields and triggers this behavior?</p>
  
  <p>An example of it working with a Stripe form would be ideal.</p>
