Google Wallet first launched in 2011 as Google's tap to pay app for Android phones, later folded into Google Pay before the Wallet name returned in 2022 for payment cards, passes and IDs.

It works much like a ding sound effect for a completed action, which is why it still reads instantly even outside a real store.
