If a signature line appears on the Merchant copy of a receipt, the cardholder must sign the receipt.
If NO SIGNATURE REQUIRED or VERIFIED BY PIN appears on the Merchant copy of a receipt, a signature is not required.
If a signature line appears on the Customer copy of a receipt, you (the merchant) must sign the receipt.
A "signatureless" transaction is a swiped or tapped Purchase for which a cardholder signature is not required because the Purchase amount is at or below the card's maximum Signatureless Dollar Value ( SDV). Depending on the card type and how your terminal is configured, receipts may or may not print for a signatureless transaction.
To configure receipt printing, see Configuring Receipt Printing.
Note: Signatureless transactions for swiped purchases apply only when a customer uses a swipe-only card, not when the customer is instructed to swipe a chip or contactless card.
