Who cares about QR Codes?

ByDon

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!

    Last week we talked about how to activate and use dictation to write emails and documents but there is a lot more that you can do. I keep thinking about Scotty from Star Trek when he went back in time and was “**confronted with a Mac Plus**”:https://youtu.be/LkqiDu1BQXY?t=1m8s. He picked up the mouse as natural as can be and said “computer…”. That time is coming and Dictation Commands are already built into your operating system.

    Once you have dictation activated you can activate dictation commands by going to the Accessibility system preference.

    * Choose Accessibility from System Preferences.

    * Choose Dictation from the list on the left side of the Accessibility pane.

    * Click the Dictation Commands button. You can see a list of available commands in the Dictation Commands sheet.

    * A starting set of commands are enabled by default. Additional speakable items like “Open document” and “Click item” are available by enabling advanced commands using these next steps:

    * Select (check) the option to “Enable advanced commands” in the Dictation Commands sheet that appears.

    * Click Done.

    After you have enabled advanced commands, you can also create your own commands by clicking the Add Command (+) button. This lets you link a spoken phrase to an app, a menu item, a keyboard shortcut, or an Automator workflow.

    You have enabled Dictation Commands and now you can speak any of the items in this list to perform the related action. Press the Fn key twice, then say a command to make it happen, such as “Search Spotlight for the Cubs score” or “select sentence” or “new document”. Give it a try and pretty soon you will be just like Scotty and the Mac Plus.

    As a shortcut, you can speak the command “Show commands” to see a list of the commands you can say.
