Some jurisdictions outlaw payday lending entirely, and some have very few restrictions on payday lenders. Due to the extremely short-term nature of payday loans, the difference between nominal APR and effective APR (EAR) can be substantial, because EAR takes compounding into account.
Payday loans carry substantial risk to the lender; they have 10-20% default rate, and according to one study, defaults cost payday lenders around a quarter of their annual revenue.
In the traditional retail model, borrowers visit a payday lending store and secure a small cash loan, with payment due in full at the borrower's next paycheck. The borrower writes a postdated check to the lender in the full amount of the loan plus fees.
A cash advance is a service provided by most credit card and charge card issuers. The service allows cardholders to withdraw cash, either through an ATM or over the counter at a bank or other financial agency, up to a certain limit.
