Show HN: A Hand-Drawn QR Code Alternative
Unfortunately, and unlike a QR code, the data is not encoded in the drawing itself, which means an Internet connection is always needed. For URL sharing the Internet connection requirement is not so much of a problem (you'd always need that connection for browsing to the URL, unless it's a local or data URL), for everything else it may be.<p>Also, once the Meshtag service goes down or closes for good, all tags become impossible to read, which pretty much puts me off of using this for any permanent purposes. I suppose it will also have to deal with copyright infringement issues (and there would need to be a mechanism for submitting DMCA notices), but don't take my word for it. Related: it's easier to censor.<p>Whether these disadvantages are enough to make up for the fact that the codes can be drawn by hand, and can expire, only time can tell.<p>By the way, if this could be made to use squares instead of triangles, I guess it would be easier to draw on grid paper.
