🔧 Hardware Check

📱 Device details

Run this on the machine the gun is plugged into — every till, every tablet, every time you move a gun. A gun is never right or wrong on its own, only relative to the machine it is talking to.

1 · Scan a test code

Tap the box, then scan a code below straight off the screen. Paper works too — anything with a hyphen in it.

TAM-21796
A real SKU — the hyphen is what catches a wrong keyboard layout
BANCO-TEST-01
Two hyphens, so a single stray character can't pass by luck
7640183261763
A real EAN-13 — digits only, so this one passes even when the layout is wrong

3 · Can this machine take dictation?

Speaking a product name instead of typing it on the glass. Press, say something, wait. The answer is the same on every device of this model, so this only has to be done once — but it has to be done on the machine, because nothing else can answer it.

🔴 ANSWERED 2026-09-17 — and the answer is no. network on the shop tablet (Debian Chromium 152) and on the desktop (Google Chrome 152), with both machines verified online at the time — the tablet reached google.com and the shop, 200 each, minutes before. Two different builds, two different key sets, same refusal. Free browser dictation is not available to us. Dictation, if we ever want it, is a small model on our own server. The button still works: press it on a NEW device before assuming the same, because that is the one thing this card was ever for.

⚠️ This sends the audio to Google. The browser's built-in speech recognition is not offline — it uploads what you say. Fine for reading a product name off a packet; not a thing to use near a customer conversation. If this test works, that is the trade to decide: free and instant, versus a small model on our own server.

More checks

  • 🔫 Full scanner test sheet — a ladder of QR codes from 30 mm down to 10 mm, so you also learn the smallest label this gun can read.
  • 📱 Device & browser report — everything the till needs, measured, with a copy button.
  • 🏷️ Label printer: the guide lives with the repo at onboarding/08-label-printer.md, including the five faults that all look like broken hardware and aren't.

Connecting a gun: use the USB dongle, not Bluetooth. It is the manufacturer's default, needs no driver or pairing, and — the real reason — there is nothing to re-pair when it drops mid-sale.
