you need RFID tags for this kind of implementation, i doubt they implement for all items.

Clothes or electronics maybe, but if you see how decathlon implement their RFID tags in the label itself, you gotta pass the item through a machine to mark it as purchased.

Doubt lotus have such tech for now.
I'm not encouraging people to steal in any way, just curious on the business decisions they made to implement such feature. Was the risk calculated?
I agree that they should combine it, but maybe its better to keep it separate for now until it reaches a certain level of maturity and fine tuning before merging them. Not too sure whats the reasoning from the developers and management.
