An electronic receipt needs a contact to send it to: an email address or a phone number. Identity documents, home addresses and similar details are not part of a receipt — there is no reason to collect them just in case.
What to collect
- A contact for delivering the receipt — email or phone.
- The order contents: item names, quantities and prices.
- The settlement type: sale, refund, prepayment or its offset.
What not to collect
- Identity documents and addresses — they are not part of a receipt.
- Card details: you never receive them and cannot store them.
- Extra form fields lower conversion and increase your data responsibility.
What the receipt itself must contain is covered separately.
