Instagram launched its QR codes globally on Wednesday, The Verge reported. It means businesses can easily direct users to their profile on the photosharing app.

Users can now generate QR codes that’ll be scannable from any supporting, third-party camera apps. It first launched the product in Japan last year. The idea is that businesses can print their QR code and have customers scan it to open their Instagram account easily. From there, people can see store hours, buy items, or just follow the account. To generate your QR code, go to the settings menu on your profile and tap QR code. You might still see Nametag there, but eventually, it’ll become QR code. You can then save or share the image. Instagram previously deployed a similar system called Nametags, which were internal QR-like codes that could only be scanned from the Instagram camera. It’s now deprecating the feature entirely.

Tim Cook’s leadership style, and the contrast with that of Steve Jobs, is much discussed. Inc picked up on an email from the Apple CEO responding to the complaints of a developer that was made public as part of recent antitrust hearings and rather summed up his style and emotional intelligence. The email only contained one word.

How would Cook respond to the lengthy message?  He forwarded the email to three of Apple’s highest decision makers, senior vice presidents Eddie Cue, Phil Schiller, and Craig Federighi, with a one-word question: “Thoughts?” On the surface, you may think there’s nothing special about that type of email. After all, it’s a single word.  But let’s break it down. First, Cook, the CEO of one of the most valuable companies in the world, could have dismissed the original message as a small-time complaint coming from a programmer who didn’t understand Apple’s overarching goals and strategy. But he didn’t.
