[Urgent] What is the most unreadable string which can be translated to a barcode (lemmy.world)

submitted 1 year ago by [email protected] to c/[email protected]

The reason I'm asking this is the company I work for develops an application which has a barcode reader functionality. The device we develop these softwares for has a very limited resolution camera (2MP). Now they want me to set a benchmark for the maximum length barcode pattern which is scannable. So what I'm trying to do is use an online barcode generator of CODE-128 and then feed various length strings to it. If I knew what pattern results in the most dense/unreadable barcode I'd be able to create different patterns using that.

It's been a long time since I looked at bar codes, but this link is to an old printer manual that has some useful information in its appendix: https://www.cognitivetpg.com//assets/downloads/105-008-02_Programming_Manual-HTML_revC2.pdf

Code 128 has three modes, which are described on wikipedia

try finding a sequence that makes it switch modes as often as possible, that'll make it harder for the software.
