The sound comes from Apple Pay, the contactless payment service launched by Apple in 2014 for iPhone and later Apple Watch. Its brief success tone became familiar through everyday tap to pay use in shops, apps and online checkouts. As short form video grew, creators lifted the chime as a standalone meme effect, dropping it over purchases, luxury flexes and ironic spending moments. It remains popular because the meaning is understood instantly without dialogue, making even a low value buy feel like a completed, premium transaction.
