You know, it might be worthwhile to discuss what a "Magic Band" (MB) does, and does NOT do.....
First off - it doesn't hold anything but a wireless "key"
. It is not huge, and has little of what would be referred to as memory.
Focus on the KEY part..... just as your house key does not contain your kitchen, bedroom, garage or bathroom(s), an MB is nothing but a TOKEN that gets you access to something.... That "something" is a far LARGER WDW Database - a vast array of information likely contained in house sized mainframe computers from 1971
.
Why does this matter? Because while KEYS may change shape, or even how they work..... all they do is unlock the house. The REAL work is done far away, on far larger machines. That's why this development is trivial.
A REAL development would involve back end DataBase Work.... including:
1) Pulling up a PHOTO of the band holder. This would solve a LOT of Security and monetary issues at WDW. Before anyone yells..... does your driver's license hold a photo of you?
2) Full integration of WDW dataBASES. You see, they have SEVERAL, on different machines, and they don't communicate all that well
. Think "ONE House, ONE key".
3) The KEY may change.... but all "keys" will be sub optimum until WDW gets a real, modern, FAST, and MAINTAINED back end database. You are seeing "cute glitz".... the equivalent of painting a rusted 1953 Chevy bright red
. It's cute, but it's still a 1953 Chevy with 487,000 miles on it
.
All personal opinion - I'm not necessarily right, no one else is necessarily wrong.
