Apple and buy now, pay later (BNPL) payment provider Klarna are joining forces to offer customers the option to lease a new Apple device in the U.S. The tech giant announced the program, called Apple Upgrade, on Tuesday, and said that customers will be able to lease eligible iPhone, iPad, Mac and Apple Watch devices. Apple Upgrade offers 12- and 24-month leasing options for iPhone and Apple Watch, and 24- and 36-month leasing options for Mac and iPad. While Klarna is best known as a BNPL provider, Apple Upgrade is structured as a lease rather than a traditional BNPL loan. Apple Upgrade is available through Apple's website and U.S. Apple Store locations.
