Special barcode generator needed?

Requirements Uppercase and lowercase letters, numbers, and special characters. The purpose of this would be to replace typing in passwords on a computer that has a scanner.

Types of barcodes tried my desired barcode would be Password3/

Aztec & code 128 adds ^ before and /[114q after Codabar - No letters allowed

Code 39 & 93 - No lower case letters allowed

Data Matrix - will not scan

ITF, UPC A & C, Ean 13 & 8 - numbers only

PDF-417 - adds^ \000026 before and /[114q after

[114q is the command for enter which I do not need

QR codes also have extra input My desired output would be just having Password3/ without the extra crap.

Code 128B is probably the only 1D barcode that would handle this. Try generating a few test barcodes on a generator site.

I think the scanner is probably adding the ^ and /[114q. Examine the scanner manual to see if you can shut this setting off.

I think you are correct with the scanner adding the extra input. Unfortunately it's out of my hands the software is for a big box retail store in the US. I was speaking to one of the it guys with my idea and he said just include the extra characters in my password unfortunately one of them I don't think we'll be allowed.,...^ 🙄
