Is there anything similar to a QR code that works offline?
Say I have a flyer that I want to discreetly distribute and there is no internet.
Is there something like a QR code that contains the data itself and not just a URL?
This way someone with no data plan could scan the icon/code with an app and the unrecognizable bits and bytes from the icon/code would show up on their screen as a .JPEG of a flyer or something.
An NFC/RFID tag can apparently hold up to a megabyte. Also I think some devices can store the data in a different way and just transmit through RFID, meaning much more data could be accessed offline that way.
That is something I had not considered.
QR codes could be deployed on stickers cheaply. This sounds like a more expensive endeavor, albiet an interesting one.
I don’t know much about in NFC or RFID. I’ll have to look into it. Thanks for the idea.
NFC or RFID requires specific hardware (badges) whereas QR codes can be hand drawn, printed…
Absolutely. That’s what I was getting at.
Being able to run down to my local postal Service and print out QR codes on stickers for next to nothing is much more realistic.
Whereas NFC or RFID would be more expensive, not as easy or convenient to replicate and the average person knows what to do when they see a QR code and that’s not necessarily true of RFID or NFC.
