Comment on Walmart's use of digital price tags signal the future of retail shopping, but consumers are worried

AFAIK, they use RFID now so they must be changed manually but maybe someday, they will devise a price-gouging scheme involving face detection and tracking people with security cameras.
“Here comes this lady that always buys four cans of dog food despite the last price increase! Let’s notch it up it by another 20%!”

No they are wifi controlled

They are also IR controlled. A lot of them have a little window on the front of the unit, and an array of transmitters in the ceiling.

Probably different models for different sets. The set I work with are purely wifi. They have a light on them to blink is the only extra thing they do
IR on them does sound stupid though, in a store environment that can be blocked rather easily

In the Czech Republic, BILLA uses them and they respond to the RFID reader on my phone. It’s a different kind though, most have black-white-red displays.
