Okay so does that limit one person at a time in the store ? Does the door only open to them once they have input their card details ? I understand the sensors that identify when someone takes say a bottle of sauce off a shelf and then charges to customer or deletes it if they put in back on shelf but what about fruit and veg - if someone picks up an apple ? Or do they not sell fresh fruit and veg in these capsules ? Maybe just prepackaged?
