QR codes can be re­ally handy. A grid of seem­ingly ran­dom black-and-white squares can hold enough in­for­ma­tion to store web­site URLS, con­tact in­for­ma­tion, email ad­dresses, pre-de­fined SMS text mes­sages, and even your Wi-fi SSID and pass­word.

Put a QR code on your busi­ness card, and peo­ple can copy all your con­tact info into their phone in a heart­beat. Post a QR code some­where in your house, and guests can use it to in­stantly sign on to your Wi-fi net­work.

You used to need a third-party app to scan QR codes, but, with IOS 11, Ap­ple built

it right into the cam­era app. It couldn’t be eas­ier to use.

HOW TO SCAN A QR CODE

1. First, open the Cam­era app. 2. Then, point the cam­era at a QR code so it can see it clearly.

That’s it! A no­ti­fi­ca­tion should pop up with an ac­tion based on the QR code scanned. If it con­tains a Wi-fi SSID and pass­code, you can join the net­work with just a tap with­out the need for typ­ing or tin­ker­ing with the Set­tings menu. If it con­tains con­tact info, you’ll be prompted to add the per­son to your iphone’s Con­tacts.

If you’re not see­ing a no­ti­fi­ca­tion pop-up even though the QR code is well-lit and clearly in view, check to make sure the fea­ture is en­abled. Head to Set­tings, then Cam­era. Make sure Scan QR Codes is en­abled (and it should be on by de­fault).

MAK­ING QR CODES

Scan­ning QR codes is only half the fun. Once you see how con­ve­nient and pow­er­ful they can be, you may want to make a few of your own. Next time some­one comes over and asks what your Wi-fi pass­word is, imag­ine point­ing them to an in­con­spic­u­ous spot on the wall and say­ing, “Just point your cam­era at that!”

Many web­sites can quickly make QR codes for you, which you can then down­load as an im­age, print out, or just save for later re­trieval from your Pho­tos app.

A few of our fa­vorites are goqr.me ( go. mac­world.com/goqr), The QR Code Gen­er­a­tor ( go.mac­world.com/qrgn), and Qr­code­mon­key ( go.mac­world.com/qrcm). The en­cod­ing for­mat for QR codes is stan­dard­ized, so it re­ally doesn’t mat­ter which site you use, just pick the one with the fea­tures and in­ter­face you like best. ■

QR codes won’t scan? Make sure it’s en­abled in your Cam­era set­tings.
