When Disney announced the MagicBand in January 2013, they outlined goals for a piece of tech that they claim would enhance and simplify the experience for park and resort guests.

Although few companies can successfully force mass adoption of a new product or service, what Disney has created with the MagicBand will most likely cause an eventual mindset where people look back and joke about a time when they had to use credit card-like park tickets, or stand in line for a paper line skipping pass.

Of course, the MagicBand has its critics, with reasons like privacy and overt commercialism at the top of the list. An article by Ian Bogost addresses some of those points, but the standards for privacy will keep adjusting as technology changes so this article won’t get into that debate. Disney is in a unique position to make data logging and user tracking seem fun (to the extent it means you get to ride Splash Mountain sooner, or meet Mickey before your dinner reservation). The experience outweighs most people’s concerns.

Ask most anyone that has been to a Disney park and you’re likely to get an earful on their favorite experiences and best memories. Many adults remember going as a kid and, now as parents, hope their kids will develop their own fond memories. It’s that aspect of a trip to Disney that the MagicBand should address. Nostalgia is a powerful feeling and Disney knows this already. That’s partly why some things in a Disney Park look the same as they did 30 years ago. People can return time and time again and have a similar experience to the one they remember from past visits.

While the MagicBand is positioned to use technology to bring “the future” to a Disney experience, it also has the opportunity to commemorate that experience and make the memories even greater.

Maybe 30 years from now, a grandparent can share a digital retelling of his first Disney experience with his grandchild, thanks to the MagicBand. The technology already exists inside the device, so Disney most likely wouldn’t have to modify anything to make this a reality.

The blog AtDisneyAgain posted a teardown of the MagicBand and showed the hardware essentially consists of a RFID chip, long-range antenna and battery. All of these components are gathering and logging data on each of the MagicBand wearers, even if only anonymously as Disney currently claims. As an example, the long-range antenna can provide GPS-like location tracking of the wearer within Disney property. While that’s nice for allowing a server to deliver a food order easily or helping a cast member reunite a parent with their lost child, perhaps more people could benefit from the data they are creating with the MagicBand.

Why not give the collected data a second purpose and provide the guest with a nicely cataloged digital keepsake? A Disney Digital Diary.
