Which payment method would you use if you want purchases to come straight from your checking account so that you always know how much you have in the bank?

Answer: A Debit Card

A debit card is a payment that deducts the amount directly from a person's checking account.

It is gives the holder the advantage of paying directly from his bank account while making purchases and removes the need for carrying large amounts of cash.

There are no interest payments that accrue on withdrawing the money since these are not borrowed funds. Since purchases are made from own funds, there maybe a limit imposed on the quantum of daily purchases

Debit cards allow the holder to withdraw funds from ATMs of the issuing banks and a network of banks.

All the transactions made through a debit form a part of the bank statement. This enables a holder to keep track of how much is available in the checking account.
