      * @param activity        The activity on top of which the UI should be displayed.
      * @param client          The consumer of the PaymentRequest UI.
      * @param requestShipping Whether the UI should show the shipping address and option selection.
-     * @param requestContact  Whether the UI should show the email address and phone number
-     *                        selection.
+     * @param requestContact  Whether the UI should show the payer name, email address and
+     *                        phone number selection.
      * @param canAddCards     Whether the UI should show the [+ADD CARD] button. This can be false,
      *                        for example, when the merchant does not accept credit cards, so
      *                        there's no point in adding cards within PaymentRequest UI.
      * @param title           The title to show at the top of the UI. This can be, for example, the
      *                        <title> of the merchant website. If the string is too long for
      *                        UI, it elides at the end.
      * @param origin          The origin (part of URL) to show under the title. For example,
      *                        "https://shop.momandpop.com". If the origin is too long for the UI, it
      *                        should elide according to:
