Boosting an individual’s credit score may be done by adding them as an authorized user on a credit card account (tradeline) with a faultless payment history and low use.
When the credit card reports to the credit bureaus each month, the positive credit history is duplicated in the authorized user’s credit report, and the consequence is a rise in credit score. Authorized users never have the ability to spend money on
credit card account. They are paying simply for the advantage of your credit card’s payment history showing on their credit report. They don’t know who you are, where you live, or anything about you.
