It's probably worth distinguishing between QR Codes used for advertising, vs other uses.
For example, I print QR codes on the back of my business cards containing a VCard record, to make it easier to import them into an address book if needed. Or at home, I have a QR code that automatically populates credentials for my WiFi network when guests come over. It's also the easiest way to add a TOTP code to Authy or Google Authenticator.
I like to think these are reasonable uses.
- mojuba 11y agoShouldn't the uses you mentioned be covered by NFC and iBeacon in this day and age?
- TeMPOraL 11y agoGetting an NFC tag inside a business card requires special effort, while QR code is just different pixels for the printer. Even if you opt for NFC stickers, it still costs lots of money (if you want to do hundreds of cards) and effort (you have to stick and program them). iBeacon is bullshit. I sincerely hope it'll turn into something useful with time, but for now, it's just a toy for advertisers. Also, solutions add up. In our local Hackerspace, we often used a combination of QR code, plaintext credentials and an NFC sticker for things like Wi-Fi access and switching lights on/off wirelessly.
- MichaelGG 11y ago>QR codes on the back of my business cards containing a VCard record Isn't this almost certainly done better with a link to a vcard file?
- TeMPOraL 11y agoQR code can store the entire vCard, thus enabling you to read it off-line.
- MichaelGG 11y agoIs this a real concern? Someone might be on a flight without WiFi and need a digital version of your contact info because the card isn't enough?
- TeMPOraL 11y agoIt's very real. People nowadays increasingly use their smartphones as rolodexes. QR code is a quick way to enter contact details into one's address book. On the other hand, you can't expect everyone to have a mobile connection. Some people don't have a data plan at all, others may be saving their batteries at the moment. Often there may be no reception at the place where cards are exchanged (think of conferences that are in underground venues). Not to mention that giving someone a business card with a link to download contact data is just wrong on many different levels. It's using a very wrong tool for the job. To put a contact file on-line you have to host it somewhere. Then the person you gave the card to has to retype the URL. URL that, like with most of the Internet, will probably be dead in six months. Generally, the solution to the problem of digitizing the data you have physically in your hand should not involve sending packets around half of the globe.
