These are transactions where you don’t physically see your customer’s card, such as when you’re taking payments over the phone.
These transactions can be risky, because you won’t be able to check the card or see your customer – so it’s easier for people to commit fraud. If the transaction turns out to be fraudulent or invalid, you could be financially liable and you might not be able to defend any chargeback claims you receive.
For this reason, you should enter your customer's full address and CVV, your card machine will then check that these are valid entries. Also make sure you never write down or record the CVV or any of your customer's card details
You should also ensure your customer has a clear understanding of what it is they are paying for by phone, particularly if they are not able to see the goods and these will now be delivered to them some time following payment. Cardholders who do not receive what they are expecting may well raise chargebacks or seek to return the items.
You should also keep proof of dispatch and delivery of the goods or services you have provided.
