QRay | Editable QR codes @qrayLink

A QR tip from the print side: Leave a blank margin around the code. The spec asks for a quiet zone about 4 modules wide on every side. Tucked tight into a corner or dropped on a busy photo, a code that looked fine in the design file can take three tries to scan.

@oyfyby 宛名ラベル用のシールにQRを刷って貼るのがきれいだと思います。糊だとチラシの紙が波打ちがちなので

@vnowqd ランダム表示いいですね。新着順だと出した翌日にはもう埋もれるので、個人開発にはありがたいです

@hackaday the error correction is the wild part. you can cover a big chunk of it and it still scans

@HungLee billy's been sold since 1979. the page behind the qr has to survive that long too

@krishna2311998 yeah, in japan it's mostly LINE. people scan qr codes from inside LINE all the time

Day 2 of building QRay in public. The first reply on our launch post: "Printing a QR code and then spotting a typo is such a common pain." Good to know it's not just me. What's the worst thing you've ever had to reprint? #buildinpublic

チラシを5,000枚刷ったあとで、URLの誤字に気づく。 あの瞬間の血の気の引き方、経験ある人いますか。 QRayは、そんな事故のあとでもQRのリンク先だけ直せるサービスを一人で作っています。今日から日本語でもゆるく発信します。よろしくお願いします！

@Joi2James editable qr codes. print once, change where it points later. building it solo from japan qray.link/en?ref=x

@_RoadTo10M @X qr codes you can edit after printing. typo on the flyer, change the link, no reprint. solo dev in japan

@kylegawley and somehow the $150 customers send fewer support emails than the $9 ones.

A QR code tip nobody tells you: Test-scan it on the actual print proof, not on your screen. Glossy paper, a tiny size, or light-gray-on-white can turn a perfect code into a dud. Scan it from arm's length with an older phone. That's how your customers will scan it.

@vamshi_builds ctrl+F is undefeated

画質が粗いとQRってほんとに読めなくなりますよね…刷る前に、実物で一回スキャンしてほしい。 それともQR自体架空のものだったのかな笑

@EDMaumbauer And half the time the QR leads to a dead page because the place changed websites in 2021. At least the waitress never 404'd.

@cgcorporation Agree. For us, the very first reply on our launch post was someone saying the typo-after-printing pain is common. One line like that beats a week of guessing.

@Anoyroyc Agree. Nobody remembers your changelog. Everyone remembers the time you printed a typo on a thousand flyers.

@rishabhnasa Thanks Rishabh! It's always the one character nobody double-checked 😅 Good luck with Übungszeit too.

Hi, this is QRay 👋 You print a QR code. Then the link changes, or you spot a typo. Usually that means a reprint. With QRay you just edit where the code points. The print stays the same. Try it, no sign-up: qray.link/en?ref=x Solo dev in Japan. #buildinpublic
