Try making a travel reserveration for tranportation, lodging, car, etc. without one.
Never had an issue. I have a debit card, they accept it at car rental places, they take it at Hotels, I buy plane tickets.
I don’t need credit.
I have NO CREDIT SCORE, a credit score is a score on how good you are at paying back debt. I got rid of debt, I got rid of Credit cards, I own my future, I am not in debt to it.
You can pay cash for a car, you can rent, you can buy anything. Credit is not needed.
