Your debit card does not contribute to your credit history as it provides access to your funds, not borrowed credit.Checking your own credit report does not lower your credit score as it is considered a 'soft inquiry.'Contrary to popular belief, your income does not determine your credit score; it is based on repayments, credit usage, and debt management.Having zero credit history can be worse than poor credit as lenders have no data to assess your repayment behavior.
