Apple's yearly developer conference should see iOS 8, OS X 10.10, and likely some hardware.
Walmart Testing iPhone-Based Self-Checkout System for Retail Stores
We are conducting a study to assess the usability of the Walmart iPhone app's new Scan & Go feature. Scan & Go enables you to scan products with your phone and bag them while shopping in a Walmart retail store, and then use the Self-Checkout at the front of the store. This survey includes questions to help us determine if you qualify for an interview session. We are simply trying to get feedback from real people on whether this new system is user-friendly, and we think you will find participating in this study fun!
Walmart's test sessions were held earlier this week, with participants being compensated with a $100 payment and a $25 Walmart gift card for the one-hour sessions.
Details on how exactly the purchasing process works remain scant, but allowing users to scan their entire orders before approaching the checkout stand could in many cases result in significant time savings during busy shopping periods.
