Here are 7 cards, each printed with a different Chinese character that is pronounced “ài,” just like “eye” in English. The pronunciation is identical to that of the word for love in Mandarin Chinese, but only one of the characters truly means love.
If you don’t know Chinese, can you take a wild guess and see if you get it right?
The iPhone camera has a build-in QR code reader. So just point your camera to the QR code under the Chinese character on the card as if you’re going to take a picture. You’ll then see a prompt on your phone that shows you the meaning in English. The message is embedded in the QR code and your phone doesn’t need to go online to retrieve it.
