My debit card does not give that kind of detail at all. And sometimes it will say "signature purchase" when there was no signature involved.
Your online banking app/website doesn't show a difference between an ATM withdrawal and a merchant sale??? Do you have a credit union? I have 3 different banks and they all state if it's an ATM withdrawal (and the details of the actual ATM itself) and if it's a purchase it shows the merchant. Granted all 3 banks are bigger banks so maybe they have more capabilities than smaller banks, im not sure.
