What is one key feature of non-installment credit?

Non-installment credit is characterized by the ability to access funds without needing to apply for credit each time a transaction occurs. This is typically in the form of a revolving line of credit, where the borrower has a pre-approved limit. This means that once the credit is established, the borrower can use it up to the limit as needed without going through a new application process or credit check for each purchase.

This type of credit is commonly seen in credit cards and lines of credit, where customers can borrow, pay back, and borrow again, all under the same initial approval. Hence, the correct answer highlights the convenience and flexibility of pre-approved credit extensions that non-installment credit provides.
