I would love for there to be a legal requirement/warning posted on shop entrances saying "This facility uses CCTV/Facial Tracking/Phone Tracking/etc"
It would be great if this was posted, boldly, clearly. As long as there are data protection limits (only 3 month's history can be maintained, data is unrecoverably disposed of) and accommodations for those who do not consent. (If every grocery store adopts the tech, how will you buy groceries if you do not accept these practices?)
