Is there a fee if you used your debit card as credit card?
I see people recommending to always run debit card transactions as credit.
There is a similar question here as well: What does it mean to run my debit card as credit?
This seems to me like a safe and easy way - as there is no need to enter your PIN and only sometimes might have to sign for the transaction.
Is this a convenience feature or manated by law?
I tried this method out at Walmart and CVS recently and I didn't even have to sign.
Is it true that then you are protected by visa or mastercard for the purchases you make - like if someone gets your number and pin or steals your card or something?
My debit card has cash back only at select online stores, so it would benefit me a lot if I could continue using it as credit card as it is then protected "like" a credit card: I can dispute a transaction if I am not satisfied with a purchase and my money is protected in case of fraud?
I was also wondering if Chase or BofA or Wells Fargo or maybe even MasterCard or VISA imposes any extra fee for a purchase if you are using the debit card as credit card?
This new way of doing things would give me some extra security and save me some money (A Vietnamese grocery shop deducts 50 cents extra everytime I use my card as debit but waives the fee for people with credit cards)
