| The best camera for barcode reading |

As TopLoser said that the very expensive equipment had problems with the further away picture I saw this as a small challenge. Not printing, but on a Laptop-screen (1:1 zoom factor) and a P9 Lite with the app 'Barcode Scanner' from Cognex Corp. (not related to that). No big problems (2-4 search rounds) to read the code from the screen. It seems that some software is better to guesstimate that a light gray area is probably two thin lines. And because of this there's no need for the full resolution. But how they do that exactly I don't know. |

It would seem to me that buying a commercial bar code scanner would be the easy way to get the data. Lighting isn't an issue, rarely does orientation matter and, apparently, these devices look like a keyboard. I haven't played with one but it seems pretty easy to integrate. At least one states that it works on Mac OS, Windows and Linux (Raspberry Pi?) and talks to popular productivity software. https://www.amazon.com/s?k=barcode+scanner&ref=nb_sb_noss_2 |
