No, it is not necessary to have a credit card in order to use Affirm. Affirm is designed to provide financing options for consumers at the point of sale of various products and services. Instead of relying on traditional credit cards, Affirm allows users to make purchases by offering loans that can be paid back over time in installments. This means that individuals without a credit card can still take advantage of Affirm's buy now, pay later services. However, users will need to provide some personal information, such as their financial status, during the application process. This information helps Affirm determine eligibility for financing options. For more specific guidance or details, please consider visiting the relevant section on the affirm.com website.
