Usually when a credit (yes credit and not debit - I didn't mistype) card has too little available credit, some of the card balance needs to be paid off. The available credit is increased by the amount paid up to the maximum approved limit when card was issued. 

My question is: Can I also only pay with a DEBIT card exactly the maximum amount which is at that exact time in the checking/saving account to which debit card is linked? 

Basically I am asking if is possible to pay on debit card to increase the potential spending amount.
