This depends on the agreement that you have with your bank. If you have an agreed overdraft then yes, you can technically use your debit card when you have no money in your account as you will be going into your overdraft.
If you don’t have an agreed overdraft then no, you cannot use your debit card to pay for goods and/or services if you have no money in your account.
Please note Suits Me do not offer overdrafts. You can only spend what you have in your account.
