Show HN: Scan QR codes to check in guests registered via Google Forms

The overview is one of the best descriptions I have ever seen for what an app does and why I should use it. Well done.

Just a reminder to anyone using Google forms that you may exclude non-Google customers.<p>My child’s school uses them and it often the forms ask for a login. Google doesn’t necessarily respect your choice to make a form public.

What&#x27;s cool also is that this is from the West African tech scene.

The issue is, at least for me, I consider all QR codes as unsafe. Unfortunately, you don&#x27;t know where the QR code leads you before you scan it and then it is already too late. So you can&#x27;t do the equivalent of inspecting the link before you click it.<p>Recently we were in a restaurant which required scanning a QR code to get served (for some reason asian restaurants like doing this). The codes were labels attached to the menu. I told the waitress &quot;I can&#x27;t scan the codes because I don&#x27;t know who put the QR codes there&quot;. She told &quot;the codes lead to their website&quot;. I told her &quot;I don&#x27;t know that, it takes a moment to print a label that looks exactly the same to my eye&quot;. She told me &quot;it would then not point to their website&quot;. I respond if she knows what MITM attack is. She responded &quot;if you can&#x27;t afford a phone we should leave and go somewhere else&quot;.<p>The funniest is those QR codes left at random in public. I imagine scanning these is like finding a random pendrive and putting it in your computer.

Hopefully, the Googster doesn&#x27;t pull the rug out from under your feet and decide to deprecate whatever product(s) you are using of theirs. It is always something to keep in mind with using anything from G as a central part of your offerings.

I love the README&#x2F;Overview on the linked page. It&#x27;s really clear what this is for, why it&#x27;s better than other solutions etc.

I like this for the “sum is greater than the parts” aesthetic, which keeps the door open to so many applications.

Kudos for the simplicity and efficacy of your solution

I like this

This is awesome!

This is WONDERFUL.<p>EDIT: nto &quot;But for use for&quot; -- I meant &quot;But in ADDITION&quot; --<p>But - for tool&#x2F;item&#x2F;inventory management in a garage.<p>Get a cheap label printer [0], create a form of your tools&#x2F;inventory with a matched set (code on tool, code on location of tool home) - Tool home has a QR code that leads to a tab in the sheet with all the tools that live in that location, container.<p>Put airtags on the high-value tools, with links in the sheet to those.<p>but scan a code on a tool - and it tells you tool details, including owner, home, whatever data properties you like.<p>If you like barcodes&#x2F;QR codes and GIMP - You will love BarTender (seagull Software [1])<p>It allows you to make ANY type of barcode you want, QR code, badge, etc etc.<p>Its AMAZING [Free*] software. (You only pay a cheapo $500 lic if you have a high volume printer for printing thousands of product labels fast - eles; its a super powerful free program with an utterly amazing and knowledgable supprt staf f (no affiliation)<p>Here is a test I did making &quot;Card Carrying Conspiracy Theorist&quot; badges based on a comment from someone saying they were one. THe QRs go to the &#x2F;r&#x2F; profile - as does the bar code.<p>The image can be set as a template then do a merge for pics and employee data from a sheet....<p><a href="https:&#x2F;&#x2F;imgur.com&#x2F;a&#x2F;eyAxpcb" rel="nofollow">https:&#x2F;&#x2F;imgur.com&#x2F;a&#x2F;eyAxpcb</a><p>(I like Guilloche designs (the swirly woven bits you see on money)) and so I used that motif - but the QR code placement and calc is automatic via Bartender.<p>I made a bunch of labels for a cannabis company - and I tied the QRs through a tinyURL which did all the geocoding of the QR scanning so that we could send product to a particular place, and then track where and how many people scanned the QR (the QR went directly to the lab test reports for the makup of the cannibis, CBD, etc...<p>So, then you could measure which market the CBD or THC were drawing most interest - and see how sales were vs scanning.<p>anyway - QR codes get a bad wrap. They are lame for menues - but a goot idea is to scan a QR code, then just have a folder of scanned links for purusal later - as opposed to launching safari when I clearly dont ue safari. :)<p>[0] <a href="https:&#x2F;&#x2F;www.amazon.com&#x2F;qr-code-printer&#x2F;s?k=qr+code+printer&amp;page=5" rel="nofollow">https:&#x2F;&#x2F;www.amazon.com&#x2F;qr-code-printer&#x2F;s?k=qr+code+printer&amp;p...</a><p>[1] <a href="https:&#x2F;&#x2F;portal.seagullscientific.com&#x2F;downloads&#x2F;bartender" rel="nofollow">https:&#x2F;&#x2F;portal.seagullscientific.com&#x2F;downloads&#x2F;bartender</a><p>---<p>&gt;&gt;&gt;<i>scan a QR code, then just have a folder of scanned links for purusal later</i><p>These get submitted to a personal GPT and it develops a learning module for you on your home portal which then gives you the run-down of all it has learned from that location QR or Context QR or Porduct QR.<p>But without a sticker - it will use either:<p>1. handheld laser engraver of the QR<p>2. an AI derived location based on meta data<p>3. an AI location based on image analysis<p>(forgive me if I am snowballing too much on HN, but I truly believe we are at an inflection point with a velocity that is being masked from us - SAs and his Ilk are not giving the fold the truth.)
