Fast-Food Chains Are Adopting Technology to Track License Plate Numbers | Eater
"Already using license-plate recognition technology in South Korea, this chain is experimenting with drive-thru systems that can identify repeat customers to speed service or increase revenue by surfacing personalized menus and potentially storing payment details. Trials in North America have been reported, and participation would most likely require customer opt-in (for example via the chain's app); however, it remains unclear what happens to images of people who don’t want to take part, raising privacy and data-retention concerns." - Tim Forster
