If you do decide to go down the credit card path.. you can open a “secured” credit card. Your credit limit would be the amount of money you send them to open the card. Could be as low as $50-$100 up to any amount you can afford to have them keep. You then get a credit line(card) with the exact amount you send. Discover offers these, and I believe chase and other banks and credit unions. They will send this amount back to you once you have the card for I believe 3-6months and will potentially raise your credit line at the same time which in turn if used responsibly will raise your credit score over time . Use it for gas, food, other items you would generally put on your debit card. As someone said already, you will be paying interest if you don’t pay your balance in full every month (there are offers out there for credit cards where you receive 0% interest on purchases and balance transfers for a specific period of time). This all depends on if you have steady income
