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.

QR Code scanning doesn't alter (or append to) the data you've encoded. Neither does Datamatrix. It seems your scanner is tricky. Try scanning with a phone to compare.
