Click to Pay may recognize the payer using cookies.

If the payer has been recognized using cookies by Click to Pay you must show the payer's email address and provide a "Not you?" link.

When payer clicks on the "Not you?" link, use this function to disassociate the payer's application/device from the payer's SRC profile.

On onStateChange callback display the card entry form and proceed with guest checkout.

Ensure to not use cookie recognition for the rest of the session.

Note that we recommend that you do not show the "Not you?" link when the payer is recognized using their email address.
