By now you’ve probably seen one of those odd-looking white squares with a bunch of smaller square dots that make up a random pattern inside–that’s a QR code. QR stands for “Quick Response,” and a QR code is a form of barcode, just like on the packaging of nearly everything you buy.

Usually QR codes are used to store Web links–URLs–so an ad can display just the QR code instead an unwieldy and hard-to-type web address. But QR codes aren’t just for ads. They’ve appeared on business cards, in magazines and books, on coins and bills, and even on tombstones–any place it would be nice to help someone load a Web link into a smartphone but where there isn’t enough room for a URL or in situations where viewers won’t remember the URL later. And the links? They can display anything that can appear on the Web: text, photos, videos, games, and more.

Only one built-in iPhone app can scan QR codes–the Wallet app in iOS 9–but it can scan only QR codes that are associated with Wallet passes, things like airline boarding passes, concert tickets, and iTunes gift cards. For QR codes that encode any other sort of data, Wallet shows an error. It would be nice if Apple would add general QR scanning capabilities to Wallet or the Camera app, but until that happens, you’ll need another app.
There are numerous QR code scanning apps in the App Store, but if you need a recommendation, give TapMedia’s QR Reader for iPhone a try. It’s free with ads (remove them with a $1.99 in-app purchase), scans both QR codes and traditional barcodes on most commercial products, and displays the associated information within the app. It can even help you create your own QR codes.

To use a QR code scanner, launch the app, allow it to access the camera when it asks, and then point it at the QR code. Good apps will scan nearly instantly, but if not, move the camera so the QR code is centered between the guides. If even that doesn’t work, move forward or back so the camera can focus on the centered code.

Once the code has been scanned, the app will usually bring up an in-app Web browser to display whatever was encoded. For certain kinds of data, like books or grocery items, the app may go right to Amazon or a price comparison site. Good apps will also keep a record of sites you’ve scanned, so you can go back to them later, even if you can no longer scan the QR code.

So download a QR code scanning app and keep an eye out for QR codes. Once you start looking, you’ll find them everywhere–it’s a modern-day treasure hunt!

I talked a bit about the big Consumer Electronics Show last week and it is rapidly fading in the rearview mirror. I have gone to this show every year for the past decade or more. We actually exhibited our Chill Pill speakers and Hammerhead products at one CES but mostly I have come as a “buyer” to look for new products and trends.

The Las Vegas convention center is a gigantic venue and the CES show spills out into the parking lot in front but also into some of the surrounding hotels and resorts. The Sands convention center was the second largest and housed some of the more interesting booths. This was the location for 3D printing, health care, fitness, home automation, robots and drones. There were sophisticated baby monitors, constant reporting thermometers, implanted blood glucose monitors and even a company that sold wireless sensors that monitor your soil’s nutrients and moisture. Home automation was huge with several competing standards vying to challenge Apple’s HomeKit. This year more companies were showing HomeKit compatible products so I think that Apple’s vision of your interconnected home is not far off.

There are lots of ways to move from the Sands over to the LVCC but the best way is the free buses offered by CES. Cabs and the monorail are possible but the buses seem to be the fastest and they are free and comfortable. For me it was a great way to rest my weary feet for a few minutes before going to the other venue to continue walking through the crowds. At the convention center there are three main halls and the international pavilion over at the Westgate (formerly, Hilton). The Center hall is dominated by the big guys with gigantic booths for Samsung, Intel, LG and others. Those booths are usually mobbed so I quickly walked through to check out the TVs and moved on. The North Hall is where the iLounge was born and products for iPad and iPhone dominate that section. The biggest part of the North Hall, however, was the Auto section with concept cars being shown my several manufacturers including Ford, Audi, Mercedes and new electric car upstart Faraday.

In the past several years the iLounge area and the international area were dominated by all sorts of cases for iPhones and iPads. This year there were a few in each section but cases were definitely not the dominate category. Over at the international pavilion there were lots of hover boards but unlike previous years, demos of the scooters were restricted to the booth area. Nevertheless, all sorts of scooters were being shown. I searched for interesting USB-C products and found some hubs that were not quite ready for prime time and a bunch of cables. I did see the USB-C displays that incorporate a hub and that could be the real solution for the office set-up for the USB-C equipped MacBook.

I never seem to be able to coordinate my meetings by hall. It seems that I’ll have one meeting in the North Hall, the next in the South Hall and then another back at the hotel. I rode the buses a lot and got to see the whole show floor that way.

I did find some interesting products that we may add to our offerings, and had some great meetings so it was worthwhile to visit this show that is a window on future technology.

My daughter Autumn and her husband Ismael are coming to visit next week which should be fun. Then we pack up and head back to Vermont. Hopefully the weather will cooperate but it seems like warmer weather is in the forecast for the Green Mountains.
