The amazing internet infrastructure in Korea caused them to develop many service that relied on Internet Explorer, preventing them to pick up new standard as easily as countries that were later to the party. That's probably the same kind of stuff here. The US did develop a universal non-cash system decades before other countries and now is stuck with its quirks. Europe started later and is slightly better. China started even later and could just use the fact that even poor people had an internet connected computer with them at all times except in the shower.
