1000 bytes is also a huge QR code. Sure, you can do it, but I'd bet that scanning it will be very hard and impossible with some apps where that usecase hasn't been tested.

I tried to find one, but failed; did find this HN comment: https://news.ycombinator.com/item?id=18498434

It says a QR code is specified as being up to 177 pixels wide (and high I presume, because square), where they can have 2 kB of data with medium error correction.

It's a bit of a chore, but manageable to do if the data is important enough. Plus, with error correction built in, you can make some mistakes.
