x.com, twitter.com and why the QR outlives both
X changed domains, changed its logo, and changed how links preview — but a profile URL built on the handle has survived all of it, because twitter.com still redirects to x.com. Encoding x.com/yourhandle gives you the address that works today and the one people expect tomorrow.
QR codes solve a specific X problem: handles are short, which sounds easy to remember, but underscores and lookalike characters get mistyped constantly, and X search will happily show someone a parody account instead. A scan removes both failure modes.
The most common placements are conference badges, the last slide of a talk, and stream or video overlays. All three are read at a distance, so keep the code chunky: a handle URL is short enough to fit in a small, low-density code that scans from several steps back.
Every X (Twitter) code made here is static: the link lives in the pattern itself, with no redirect service in the middle that can expire, start charging or go down. There's no account, no watermark and no scan limit — download it once and it keeps working for as long as the X (Twitter) link behind it does.
