lol ok you got me, I had to look up whether they had designed it so badly
Yeah, but will that last 20% require exponentially increasing amounts of co2 production until life on the planet is destroyed and thus ensuring the supply won’t be exhausted?
Has anyone actually used a qr code for anything useful?
When they were first becoming a thing, i used them to buy bus tickets but it was more of a novelty than anything
I think they’re awesome. They’re an optical, better version of barcodes. I’m sure there’s a bunch of specific industrial use cases. What’s cool about them is the error correction so you can do stuff like this where the middle is carved out. There’s also a standard way of sharing Wi-Fi networks as QR codes, so you could have a QR code of your home Wi-Fi network SSID/password to share with guests instead of having to dictate it to them.
if anything they seem to be getting more popular recently. Restaurants have QR codes on the tables now for accessing menus, many countries use QR codes for Covid passes, lots of countries use a QR code digital signature for government form authenticity. Seems like they might have gotten their start for making purchases in Asia or a gimmick on a bus stop poster but they’re used for a bunch of things now.
Sharing multi-factor authentication secrets and transmitting small bits of information from a computer to a smartphone are their primary use cases for me.
SQRL (Secure Quick Reliable Login) is a password-less authentication protocol developed by GRC that’s awesome and uses QR codes if you use a smartphone SQRL client, but it’ll probably never catch on.
depleted qranium :kelly:
that’s a functioning QR code by the way, I’m doing my part.
