This is incorrect.You cannot decide when to take the secured deposit back-only the credit card issuer can do this.Also, shredding a card is a bad move as creditors will lower your credit limit or even cancel your card if it is not used somewhat regularly.The end result of this will be one less line of credit and a lower credit limit (which can make it harder to keep your utilization low),thus resulting in a lower credit score.
If your teen is ready for their own card, a secured credit card is a good place to start. A secured card is similar to a traditional “unsecured” card, except it requires a security deposit to access credit. Your teen can build credit by charging a small amount each month to their secured card and paying it off in full and on time each month. They can eventually upgrade to an unsecured card, and we’ll explain how below.
With poor credit, you may not be able to get approved for new credit products like credit cards. Although you may still be able to take out an auto loan or a mortgage, you’ll pay a much higher interest rate because of your low credit score. Compared to a borrower with good credit, someone with poor credit can pay $50,000 more in interest on a mortgage. Over an entire lifetime, you could end up paying over $200,000 more in unnecessary interest just because of bad credit.
