collecting data from a payment

Use this link https://ardfertmedicalcentre.ie/private-perscriptions/

The client wants to marry up the data collected with the data from the card user online. The ‘online services’ section uses ninja forms and the conditional logic plugin to allow for payments.

The issue they are having is Mary might need a prescription, but John might have paid for it. Is there any means by which the card users id within stripe for example can be shown on the automated receipt the client and/or user receives?

Thanks in advance as this has my head in a spin.
