[rpsypwkz] Pictures at an amusement park

At the entrance, you have the opportunity to associate your face with an e-mail address.

Then, cameras both automatic (e.g., on roller coasters) and park staff, take pictures of you, and e-mail them to you using face recognition.

A slightly lower tech solution is a sticker or temporary tattoo with a barcode (e.g., QR code).  If a temporary tattoo, the service can helpfully edit out the barcode and replace it with skin tone.

Pictures from fun times can help encourage repeat visits, helping pay for the capital investment.
