Technically, these digital tags are being developed to automatically update price from a database, so there is a computer somewhere.

I think they’re just e-reader technology that accepts input by RF or something. Probably has an RFID on it, so a control node just (1) scans the RFID, (2) looks up price of product for that RFID, (3) send signal back to update the display. Because I’ve looked at these things. I don’t see any modules for wireless communication over lan, Bluetooth, or anything like that.
