Amazon has its own unique set of QR codes charmingly called “SmileCodes.” You might even have come across a SmileCode in your day-to-day routine. To access these SmileCodes, you just need to open the Amazon app, tap the Camera icon and select SmileCode.
These codes can be used to unlock contextual “Amazon experiences,” which can range from useful functionality to exclusive promotions and deals. But they can also come in handy. If you use an Amazon locker, for example, you just need to scan the SmileCode to instantly bring up your unique package unlock code.
