It did deliver the message to Garcia.

Hi HN! Collecting form responses is one thing, but once you try to use them, a lot of them turn out to be unusable. Some are missing critical information or answering the wrong que…

Hey HN, I built something I've been wanting for years: a way to access the power of Google Apps Script inside Sheets on demand, without having to switch to the code editor and reme…

This is the fundamental weakness of every self-check-in system. QR codes are just information, and information can already be transmitted instantly and faked (GPS, etc.) if needed.…

Ah, I was assuming numeric data rendered as hex, like UUIDs. Decimal works wonders for those, because the numeric mode of QR codes is the most efficient.

Hex is worse, see here [1] for UUIDs [1] https://news.ycombinator.com/item?id=39094251

This is particularly useful for numeric data that is usually displayed in hex, like UUIDs [1] I used this for digital QR code tickets [2], and it made the codes so much easier to s…

I'm building a point/credit/voucher tracking tool for QR code member cards. https://workspace.google.com/marketplace/app/qr_code_loyalty... You create a new member by filling a Goo…

That's neat, especially for arbitrary binary data!

Physically bigger pixels help a lot indeed. The encoding mode also helps make pixels bigger. This is very convenient when you control the QR reader and need to represent long numer…

Thanks, please get in touch when you do try it!

Thanks, please don't hesitate to get in touch when you do try it!

Thanks tchalé ;) Btw, my parents never managed to decide if they were Togolese or Ghanaian

Mostly nation by nation, but key hubs like Nigeria/Ghana (English) and Senegal/Ivory Coast (French) draw other countries in, due to the presence of a larger pool of investors.

Spot on. Fortunately, the underlying platform itself is independent of Google. The Forms and Sheets add-ons are just customer acquisition channels, just like our Zapier integration…

Indeed; I didn't expect this level of interest, to be honest. The HN demographics didn't seem to match my target market.

It depends on which app you are using to scan the codes. For Trak [1], the main use case is to scan QR codes you made yourself (or someone from your company made). The scanner simp…

Wow, happy to find another QR code enthusiast here! They simplify a lot of things, indeed. Great use case! I did a tool inventory management use case once, with the underlying plat…

Thank you! I stole [1] this structure from "Obviously awesome" by April Dunford. [1] https://news.ycombinator.com/item?id=38786113

Thank you! The main platform is currently used by national post offices (physical mail tracking), health organizations (biological samples), banks (fixed assets tracking), manufact…

Thanks! I stole this structure from Obviously Awesome [1] by April Dunford, highly recommended. I just noticed the main submission link goes to the Google Sheets add-on, instead of…

Ah indeed ;)

Indeed. This happens when the form is configured to collect "verified" emails. A form can use a custom field (doesn't require login), user input managed by Google Forms (named "Ema…

Busted! Curious what gave it away, my username?

Hi HN! I made a no-code platform for creating physical data collection apps, using QR codes [1]. It does not yet have a self-service config UI though, which limits adoption. That's…
