New blog post! Inspired by my recent trip to China, I dive into 16 examples of how QR codes bridge the online/offline divide and enable a whole new set of mobile experiences. Thread 👇a16z.com/2019/10/30/the…
Here in the US we’ve been slow to adopt QR codes outside of messaging apps. But they’re full of potential; camera-based solutions like QR codes can give instant fixes to clunky user experiences, while also enabling us to log in to physical locations.
Logging in to physical spaces allows brands to learn user identity/preferences, while customers gain a more tailored and social experience, as well as perks like automatic loyalty programs built into every transaction.
Take, for instance, my favorite bar in Nanjing. In the video, you can see live posts on the bar's app. I scanned a QR code to log in to the bar and could instantly see profiles of who was there. Those looking to pick up dates can even dm online before making moves irl.
Shared power banks for charging phones are now extremely common. Because QR codes link to identity on WeChat/Alipay, over 95% don't require deposits. They’re everywhere, even near Mt. Tai’s peak, 6,000 steps up, to ensure hikers have enough juice for the all-important selfie. 
Vending machines for fresh-cut flowers are certainly possible in the US with credit card payments, but by linking to WeChat via QR codes, the retailer gets access to customer information and can easily build loyalty programs and retarget buyers.
I detail these and other examples, from sample vending machines to capsule gyms. Final notes:
1) Tech evolves fast in China -- most of these products were nonexistent when I lived there just 3 years ago.
2) These examples are by no means ‘magical’ in China; they are the norm.

As the saying goes, 一个好汉三个帮; thanks to @conniechan, @laurenmurrow, and 夏秋雨 for help with this post!
To those curious, this was the inside of the capsule gym in Beijing I worked out in. Limited equipment, just a treadmill, pull up bar, and dumbbells. Comes equipped with air filter, AC, and views of the nearby hand-pulled noodle restaurant 🤤
