Virtual Supermarket

Quick Response codes are a type of matrix barcode (or two-dimensional code) designed to be read by smartphones. The smartphone train left the station without me, as I continue to use a cell phone with little intelligence (as I recently described it, an abandoned caboose on a spur line no longer in use). QR codes are everywhere, with a recent and explosive 1200% increase in their use in North America alone.

There is literally no end to how they can be used, including shopping for groceries in the subway. Since I found this article, China has also added this technology in cities such as Shanghai and Beijing.

Not quite shopping in your jammies, but still pretty convenient. This week, a look at Virtual Supermarkets.

TTFN, Fred.
