The Upside—and Downsides—of QR Codes

Why advertise your site when you can send someone directly there?

You probably recognize the weird box of pixels at the top of this article. It’s called a QR Code—quick response—and it’s a way to box up some information, often a link to online content, and put it on the printed page. You scan it with your mobile phone, and suddenly you’ve got a wealth of information.


The codes do double duty: They make some things easier (like let you put your airline’s boarding pass on your smartphone rather than scramble to find a printer), but they are becoming ubiquitous in advertising. QR codes are billed as a way for advertisers to increase engagement and gain useful metrics—the codes can indicate exactly how many people thought an ad merited further investigation.

Anyone can make a simple QR code that links to a website or relays information. In a world where we’re using cellphones to make plans and track our schedules, it only makes sense to stick a QR code on the flier for your band’s next show: Potential fans will not only be taken in by the compelling visuals (nice dragon, man) but can snap the code and save the venue and date automatically.

We’re still figuring out QR codes. They’re not quite as ubiquitous as their proponents would like them to be, and educating people to take advantage of them will take time. But as our augmented-reality future draws ever closer and we use technology to gather and sort more and more pertinent information from the world around us, QR codes are another way of lowering the barrier between the analog world and the digital one.

We no longer have to get up to turn on the lights or set the thermostat, we can find the fastest route to work with a click, and, most importantly, tag our friends in pictures. But interacting with the world isn't the only thing AI is making easier – now we can use it save the world, too.

The anonymous staffer says that Trump once feigned a Hispanic accent and made fun of women attempting to immigrate to the U.S.

The 63-year-old Oakland-Alameda Coliseum, currently branded the RingCentral Coliseum, is one of the most decrepit sports venues in America.

The home to the the NFL's Oakland Raiders (until they move to Las Vegas next season) and MLB's A's, is notoriously known as the Black Hole and has made headlines for its frequent flooding and sewage issues.

One of the stadium's few positive aspects is its connection to public transportation.

Yad Vashem

Since 1992, the Jewish Foundation for the Righteous has been holding reunion ceremonies between Holocaust survivors and rescuers once a year. But the tradition is coming to an end, as many have died or are too frail to travel. What might be the last reunion of its kind took place when a 92-year-old woman met up with the two surviving family members that she helped hide during the Holocaust, and their descendants.

Sarah Yanai and Yossi Mor introduced Melpomeni Dina (nee Gianopoulou) to their almost 40 family members, all decedents of the Mordechai family, the family of seven that Dina and her two sisters hid during WWII. "There are no words to describe this feeling," Dina told the Jeruselum Post. "It is very emotional for us to be together again."
