Credit or debit: who was never in doubt when choosing which one to use to pay for a purchase?

Both are forms of payment that have their advantages and disadvantages – and the choice depends on your financial planning. Credit and debit are different payment methods. So it is important to keep in mind how each of them works: using the debit or credit at the wrong time can bring problems to your budget at the end of the month. It is important to plan when using debit if you also use your credit card on a daily basis: after all, close to the expiration date of your invoice, you need to have enough balance to pay for purchases made on credit.


The Debit Card is the simplest and safest way to pay for your day-to-day purchases, be it a simple newspaper, bakery or even the supermarket in the month. You have the peace of mind of not having to withdraw or carry money in your wallet and don’t waste time waiting for change.

It is also possible to use your debit card for online purchases at selected stores and a secure virtual environment.

You can pay for all your purchases without withdrawing money. The purchase price is debited directly from your checking account. The debit card, you make purchases using the security devices and passwords offered by your bank. The debit card uses your current account balance – or digital account, depending on the financial institution where you have an account – to pay for your purchase. In other words: the money comes out of your account on the spot, like a withdrawal. Why do I need to have a plan to use the debt? If your balance is less than the purchase amount, it may not be approved – or, if you have a credit limit at the bank, making a debit purchase can leave your account balance negative. For this you need proper planning for financial managementIf there is no planning, paying in debt can also result in debt. It all depends on your financial planning: you can choose, for example, not to have a credit card and concentrate all expenses on the debit, just as you can also spend only on the credit card – and any other combination that is more appropriate for you.


The debit card works differently than a credit card – and it impacts how you use your debit. Debit cards are often called “plastic money” since, to make a purchase with it, just insert the card into the machine, enter a password and that’s it: payment approved. But in practice, how does a debit card work?

To make a purchase using a debit card, you need to have the balance in your checking account, savings account or any other type of account you have – NuConta, for example, is a media account payments that have a debit card. 

If the user does not have the necessary balance to pay for the purchase, there are two consequences:

  • The payment is not approved;
  • The payment is approved, but the user enters the overdraft , if he has a credit limit;

To make a purchase on the debit card, it is necessary to verify the transaction with a password of four or six digits, depending on the bank that issued the card – and hardly any cards that only have the debit function are defrauded; this is more common with cards that also have a credit function. Therefore, the debit card is considered more secure than physical money.

But there is a care to be taken when making purchases on the debit card: ensure that you have enough balance for the purchase. The big problem is not the purchase being denied, but having a negative balance: daily interest is applied to it. Depending on your bank, the interest rate on overdraft can reach more than 14% per month or 400% per year; the Central Bank has an updated table of fees that each bank charges for overdraft. In addition to interest, if the customer overflows the overdraft limit or does not have the money on account on the day of payment, the bank may charge a fine on the debt.
