All sorts of 'verify by Visa' rely on 3DS (Three Domain Security) and were designed specifically for online transactions. They do not really exist for offline transactions as there is an assumption a seller will either verify the signature (not really used any longer) or cardholder will authenticate via PIN.

Showing a card at product pick-up is a reliable and cheap fraud check method
