The worst part of all is that no one would think of the fact that a vending machine is performing facial recognition techniques, because in general it is assumed that a vending machine is a mechanical device, as it has been in the past. There is not any user benefit in that.
I researched the manufacuter and in their brochure (see page 6) of a similar vending machine it is revealed what data can be processed:
Among the worst data sets are:
- product demographics
- measuring of foot traffic
- gender/ age/ etc.
Bonus: on page 7 of the product brochure they introduce an app which allows the customer to make purchases directly from their smatphone, with features like
- consumer engagement through gamification, interactive marketing, gifting, scratch-and-win receipts, product sampling and cross selling
"What do customers get?"
- a fun and engaging payment process
Finally! I always thought that payment is not fun enough. What a time to be alive.
