Line, which operates Japan’s most popular smartphone messaging app, is moving quickly to expand Line Pay, a mobile-payment system it launched in December. The Japanese unit of Korean Internet giant Naver said Tuesday it has signed an agreement with CyberSource, a U.S.-based global e-commerce payment company owned by Visa, to work together as strategic partners. Line said the alliance with CyberSource, whose payment management and security services are used by over 400,000 businesses worldwide, is aimed at accelerating Line Pay’s growth outside Japan, but declined to share details of their planned cooperation. Line Pay’s success is far from guaranteed, especially outside Japan. Just about all of the major players in mobile technology and services, from Google and Apple to Samsung Electronics, are trying to gain control over payments.
