Huh. Now you've got me wondering... Could you leave a device hidden in store that receives the IR signals that program the tags, capture that information, then parse it out later? You could literally log prices changes at the shelves, in real time.
I don't think they're IR. Something similar to wifi. Surely encrypted.
Looks like there are two varieties - IR or Bluetooth Low-Energy (BLE).
