A credit system is an arrangement in which purchases made by a customer are recorded and the customer can pay back the amount due over a period of time. There are several synonyms for a credit system, including credit score, credit rating, credit report, credit limit, and creditworthiness. A credit score is a numerical value that reflects a person's creditworthiness and the likelihood of repaying debt. A credit report is a detailed summary of a person's credit history, listing all credit accounts, payment history, and outstanding balances. A credit limit is the maximum amount a borrower can borrow, while creditworthiness refers to a borrower's ability to repay debt.
