Apple Pay launched in the United States in October 2014 as Apple's contactless payment service for iPhone and Apple Watch, letting users pay by tapping a device instead of using a card. Its short success chime became familiar from shops, transit gates and online checkouts. As phone-payment videos grew on social media, editors lifted the sound and reused it out of context as a shorthand for spending money, showing off a purchase or pretending a tap had just cost someone a lot.
