The buy now, pay later system could help drive Apple Pay adoption and convince more users to use their iPhone to pay for items instead of standard credit cards. Apple receives a percentage of transactions made with Apple Pay, driving additional revenue to the company’s more than $50 billion per year services business. The service is currently planned to work as follows: When a user makes a purchase via Apple Pay on their Apple device, they will have the option to pay for it either across four interest-free payments made every two weeks, or across several months with interest, one of the people said. The plan with four payments is called “Apple Pay in 4” internally, while the longer-term payment plans are dubbed “Apple Pay Monthly Installments.”
