I second qrencode. It is notoriously used by the password-store [0]. Theirs qr function is perfect to extract as a separate script and put them into the $PATH (especially useful when it is needed to generate and save some QR codes). The opposite tool to qrencode is zbarimg, which accepts first parameter to image file containing the QR code and prints out the encoded content.
