What happens when you swipe a debit card as credit?

Consequently, what happens if I swipe my debit card as credit?
When you run your transaction as credit using your debit card, you are still authorizing a debit from your checking account. You will never be charged interest or receive a bill for doing this. Of course, choosing credit at the point-of-sale will not help you build your credit.
Similarly, how do I use my debit card as credit? Select “credit” on the customer card terminal's screen or, if there is no customer card terminal, inform your cashier that you'd like to run the card as a credit purchase rather than a debit purchase. Unlike a debit purchase, you will not need to input your PIN when using your debit card as a credit card.
Also question is, can I use my debit card as credit with insufficient funds?
Many banks allow credit and debit card transactions to go through, even if the card user is over their credit limit or has insufficient funds in their checking account. Add in any additional over-limit fee or continued NSF fee to that cost and you've got yourself one very expensive latte!
Can debit card be swiped?
Also, here's how to select each option. If you want to sign for a debit card transaction, you generally swipe your card through the reader and choose "credit" — even though you are authorizing a debit (withdrawal) from your account, not a credit card transaction. To use your PIN instead of signing, select "debit."
