Rule summary

Be Respectful: Harassment, hate-speech, bullying, personal attacks, slurs, or threats are never allowed. Treat everyone like a real human.
Stay On-Topic: Content must focus on QR codes: creation, scanning, troubleshooting, design, use-cases, standards, art, security, etc. Tangential “tech news” or memes that don’t feature a scannable code will be removed.
No Illegal Content: State clearly that illegal content, including pirated materials and illegal activities, is not allowed.
No Misinformation: If applicable, you might want to include a rule against spreading false or misleading information, especially if your subreddit deals with sensitive or factual topics.
Quality & Functionality Required: Codes (or screenshots of them) must be readable and actually scan. If sharing AI-generated/arty codes, prove they still resolve correctly (gif/video or decode screenshot). Blurry, low-effort, or broken images may be removed.
No Self-Promotion: r/qrcode is a learning and discussion space, not a billboard—posts or comments that plug your own product, service, social profile, affiliate link, Kickstarter, or any QR code leading to them will be removed. If you think your open-source tool or research genuinely benefits the community, get mod approval before posting. Violations lead to removals, warnings, and eventual bans.
No Malicious or Unsafe QR Codes: Do not post QR codes that link to malware, phishing pages, credential harvesters, payment scams, or anything illegal. Always include plain-text disclosure (the exact URL/text the code resolves to). QR-code scams have spiked in the past year, so zero-tolerance here.

Works well

Show off a clever or well-designed QR code use case, with a working code and a plain-text note of the URL it resolves to
Post an artistic or AI-generated QR code together with a video or decode screenshot proving it still scans
Ask a genuine troubleshooting question about why a code will not scan, with a readable image attached
Post a code and invite people to test that it scans, which the community description explicitly welcomes
Ask a real question about QR standards, security, or design practice
Get moderator approval first, then share an open-source tool or research that genuinely helps the community

Avoid

Posting any link, comment, or QR code that plugs your own product, service, social profile, or affiliate link, since “No Self-Promotion” removes these and repeated violations lead to bans
Sharing a QR code without a plain-text disclosure of the exact URL or text it resolves to
Posting blurry, low-effort, or broken QR code images that fail “Quality & Functionality Required”
Sharing an artistic or AI-generated code without proof that it still scans, like a video or decode screenshot
Posting memes or tech news that do not feature a scannable code, which “Stay On-Topic” removes
Linking to anything malicious or illegal, which gets zero tolerance under “No Malicious or Unsafe QR Codes” and “No Illegal Content”

What r/qrcode Is For

This is a community for people who make, scan, and think about QR codes. The public description says it is a place to share, scan, and discuss them, whether you are showing off a cool use, asking for help, or troubleshooting a problem. The rules list the topics that count: creation, scanning, troubleshooting, design, use-cases, standards, art, and security. The people posting here are hobbyists, designers, and people who use QR codes in real projects, and the description even invites you to post a code so someone can test that it scans.

Rules That Matter Before Posting

The rule that decides most things here is “No Self-Promotion”. It says the subreddit is a learning and discussion space, not a billboard, and it removes posts or comments that plug your own product, service, social profile, affiliate link, or any QR code leading to them. There is one exception worth knowing: if you built an open-source tool or did research that genuinely benefits the community, you can post it, but only after you get moderator approval. “Quality & Functionality Required” means any code you share must be readable and actually scan, and artistic or AI-generated codes need proof they still resolve, like a gif, video, or decode screenshot. “No Malicious or Unsafe QR Codes” requires a plain-text disclosure of the exact URL or text your code resolves to, and it has zero tolerance for anything shady. “Stay On-Topic” keeps content focused on QR codes, so tangential tech news or memes without a scannable code get removed. Finally, “Be Respectful” covers how you treat people in comments and replies.

What To Post

The safest and most welcome post here is a working QR code with a story. Share a cool or clever use of a QR code, make sure it scans, and include the plain-text URL it resolves to. If you made something visually interesting, like an artistic or AI-generated code, show it working with a video or a decode screenshot. You can also ask genuine questions about creation, scanning, troubleshooting, design, standards, or security, and the description says you can post a code and someone will scan it for you. If you have an open-source tool or real research to share, message the moderators first and get approval before posting. Notice that none of these require you to pitch anything. You earn attention here by being useful.

What To Avoid

The fastest way to get removed here is self-promotion. Do not post your product, service, social profile, or affiliate link, and do not post a QR code that leads to any of them. Do not post your open-source tool or research without moderator approval first, even if you think it helps the community. Do not share a code without a plain-text disclosure of where it points. Do not post blurry, low-effort, or broken images, and if your code is artistic or AI-generated, prove it still scans. Do not post memes or tech news that do not feature a scannable code. And never post a code linking to malware, phishing, scams, or anything illegal, because that gets zero tolerance.

Common questions about r/qrcode

Can I post my open-source QR code tool?

Yes, but only with moderator approval first. The rule says open-source tools or research that genuinely benefit the community need approval before you post.

Can I share a QR code that links to my landing page?

No. The rule bans any QR code leading to your own product, and posts or comments that plug your product get removed.

Can I show off an AI-generated QR code design?

Yes, AI-generated and arty codes are allowed, but you must prove they still resolve correctly with a gif, video, or decode screenshot.

What should I include when I post a QR code for testing?

Include a plain-text disclosure of the exact URL or text the code resolves to, and make sure the code is readable and actually scans.

Can I ask for help with a QR code problem?

Yes, the description says you can show off a cool use, ask for help, or troubleshoot, as long as the content stays focused on QR codes.
