Digital Signs or AR? What becomes mainstream first? You can see digital price tags in Big Camera (Best Buy equiv.) in Japan. These digital signs could introduce interesting economics in physical stores, like dynamic pricing, personalization markets, etc https://bloom.bg/3CXBSqv
Digital price tags are widespread in supermarkets (low-cost and high-end) across Australia and Asia. Not the same in the US?
Dynamic pricing likely to be gamed by consumers, possibly leading to regulation (as with insurance) — consider daigou wrt baby formula and luxury goods: https://www.bloomberg.com/news/articles/2021-07-21/china-s-daigou-shoppers-who-buy-goods-overseas-get-grounded-by-pandemic
Owning a store and controlling the price tags seems different to owning a car and gov’t controlling the plates. Would be like the store giving up control of the price tag to the brands they displayed. On a car it feels like one step away from a publicly displayed social score.
Practically; digital signs make sense when you want to broadcast controlled information, and AR makes sense when you simply want to validate it when required (like QR). Far less infrastructure required for the latter too.
