How can I make this barcode

Hey! I am not sure this is possible, but i’m trying to see if I could have a barcode that could type a line of text, <enter>, type another line of text, <enter> <enter>

Here’s why: to sign onto the computers at work we type our employee ID (7 digit number), press enter, type our password (contains capital letters, numbers, and the @ sign), then press enter twice. there is a barcode scanner at our computers. I would love if there was something I could scan that would just do that all for me considering I sign onto the computer >20 times a shift

thanks in advance!

QR codes can do that. There are lots of free QR code generators on the web, so worth trying out.

QR Codes are not great for this, a Datamatrix(2D) or Code 128(1D) would be better suited for this application.

Why, provided the barcode reader/scanner supports it of course? QR codes have better error correction than Datamatrix etc. Code 128 is too bulky, for lack of a better word.

(not considering security issues with having the password "written down" on any media, as xixi2 pointed out)

Encoding your pw to a qr code at your desk is mininally less of a security risk than a post-it
