This is a product of the extremely close ties between the Disney & Apple Corporations, as originally forged by Steve Jobs.
Like anything else it's both beneficial & nefarious. (pros & cons)
Guests of the Park, or Resort, are given the "warm & fuzzy story". It's for your convenience, your child's safety, blah...blah...blah.
Yet Reality runs far deeper, as the data collected about you, complete with facial recognition & full length pictures collected via thousands of surveillance cameras hidden at all heights, angles & positions around the resort are combined with your credit card data, and biometric data gleaned from sensors deployed in various touch points (think bracelet).
This is neither a gloom & doom, nor "big brothers watching post" it's simply someone very close to the project, sharing whats really happening "for your safety".
It's high tech at its finest
