I noticed that while I was working at cvs if I take someones debit card and swipe it on my screen then it charges to either MasterCard/Visa $$$$ on the receipt but when they swipe it in front it asks for a pin and on the receipt it says Debit $$$$
i have a citibank debit card and i was wondering when i use it at mcdonalds or wendys does it charge to credit if even possible? because i have a debit card with only a checkings account.
Because at fast food places whenever i swipe my card its all set doesnt ask for a pin or anything, does it directly take off money from my checkings?
Or is it because at cvs they can give you cash back and thats why you need a pin
